The National Oceanic and Atmospheric Administration (NOAA), organized in 

1970, has evolved into an agency that establishes national policies and manages 

and conserves our oceanic, coastal, and atmospheric resources. An 

organizational element within NOAA, the Office of Fisheries, is responsible for 

fisheries policy and the direction of the National Marine Fisheries Service (NMFS).

In addition to its formal publications, the NMFS uses the NOAA Technical 

Memorandum series to issue informal scientific and technical publications when 

complete formal review and editorial processing are not appropriate or feasible. 

Documents within this series, however, reflect sound professional work and may 

be referenced in the formal scientific and technical literature.

Summary

The Marine Mammal Protection Act (MMPA) requires the National Oceanic and 

Atmospheric Administration (NOAA), National Marine Fisheries Service (NMFS), to document 

human-caused mortality, non-serious injury (NSI), and serious injury (SI) of marine mammals as 

part of assessing marine mammal stocks and to evaluate human-caused injury and mortality 

levels in the context of potential biological removal (PBR) levels calculated under the MMPA 

(Wade 1998). NMFS defines SI as “any injury that will likely result in mortality.” While 

documenting mortality is straightforward, distinguishing NSI from SI requires reliable data on 

injury severity and animal condition, often in challenging environments where thorough 

examination of injuries is not possible. NMFS updated its SI designation and reporting process, 

which uses guidance from previous SI workshops (Angliss and DeMaster 1998, Andersen et al. 

2008), expert opinion, and analysis of historic injury cases to develop new criteria for 

distinguishing SI from NSI (NMFS 2012a, 2012b; NOAA 2012; Moore et al. 2013). 

This report contains updated records of human-caused injury and mortality to pinnipeds 

and cetaceans from 2008 to 2012, for marine mammal populations that occur in U.S. west coast 

waters and which are evaluated in Pacific region marine mammal stock assessment reports 

(SARs) (Carretta et al. 2013a, 2013b). Mortality records, while included in this report, were not 

evaluated for SI/NSI status. Subsistence and directed takes (i.e., gray whales taken by Russian 

natives) are not reported here but are reported in SARs published by NMFS. Previous records, 

including cases from 2007 reported in Carretta et al. (2013a), are archived online together with 

2008-2012 records from the current report. These are available at swfsc.noaa.gov/Bycatch.aspx. 

Sources of injury data include strandings, disentanglement networks, and fishery observer 

programs. Stranding network data includes records of injured marine mammals at sea and 

ashore reported by the public, as well as researchers. Injury sources include, but are not limited 

to, vessel strikes, gillnet entanglement, pot and trap gear entanglement, shootings, marine debris 

entanglement, research-related injuries/deaths, hook and line fishery interactions, and power 

plant water intake entrainment. This report covers the 5-year period from 2008 to 2012, which 

includes injury and mortality data used in preparation of Pacific marine mammal stock 

assessments. Most records originate from stranding networks in California, Oregon, and 

Washington, though a few Alaska records of Eastern North Pacific gray whales (Eschrichtius 

robustus) are included, because this population is assessed in the Pacific region SARs and occurs 

along the U.S. west coast. Other marine mammals such as Steller sea lions (Eumetopias jubatus) 

occur in California, Oregon, and Washington waters, but they are assessed in Alaska region 

SARs and are not included in this report (Allen and Angliss 2013). Injury determinations for 

Pacific region species/stocks in the central Pacific from Hawaii westward are also included in 

separate reports.

Methods

 The assessment of marine mammals for signs of human interaction, whether alive or 

dead, requires application of systematic forensic protocols, combined with expertise in 

diagnosing trauma (Moore et al. 2013). Stranding network personnel may have varying regional 

standards for assessing the causes of death and injury in marine mammals, which often involve 

examination of carcasses in challenging environments that makes thorough examination difficult 

or impossible. With respect to the uncertainties in determining whether injuries or deaths are 

human-related, we reviewed stranding records, including at-sea sightings, from NMFS 

Southwest, Northwest, and Alaska regional stranding networks. Those records with humanrelated causes of injury were evaluated using the new SI criteria. Animals whose initial 

reporting condition was ‘dead’ were not evaluated for SI and their records are included in NMFS 

stranding databases, bycatch reports (Carretta and Enriquez 2009a, 2009b, 2010, 2012a, 2012b; 

Jannot et al. 2011; Breiwick 2013), human-caused mortality sections of SARs, and Appendix 4 

of this report. Different criteria for injury assessment are used for three taxonomic groups: 

pinnipeds, large whales, and small cetaceans (NMFS 2012b and Appendices 1-3). Injury 

determinations include 846 records for the period from 2008 to 2012. Both initial and final

injury determinations are given for each record. For example, a pinniped entangled in gillnet 

that is constricting or impeding movement is considered seriously injured. This animal may be 

captured, taken to a rehabilitation center, treated for injuries, and released back into the wild 

without serious injuries. In the context of categorizing commercial fisheries (based on levels of 

SI and mortality) for the NMFS List of Fisheries (LOF), this pinniped is considered seriously 

injured. This allows evaluation of fishery-specific risk to marine mammals, even though the 

pinniped was released back into the wild with non-serious injuries. Similar cases involve large 

whales entangled in fishing gear and subsequent disentanglement efforts. The whale’s injuries 

may initially be considered serious, especially if the entanglement restricts movement. 

Successful disentanglement of all gear from a whale without lingering evidence of an 

entanglement-related health decline or SI may be designated as a NSI. For purposes of the LOF, 

initial injury assessments are used in evaluating individual fisheries. In the context of assessing 

SI and mortality against PBR levels, the final injury assessment or condition is used. Special 

cases involve injured pinnipeds transferred to public display facilities (aquaria) or U.S. Navy 

marine mammal programs following treatment, because their survival in the wild is questionable. 

In these cases, the final injury determination is termed ‘captivity’, as the animal is permanently 

removed from the wild population. This is equivalent to a SI for the purposes of evaluating 

injuries against PBR. 

 Most records contain a single anthropogenic source as the cause of injury or death, but 

animals may show signs of trauma from multiple sources. For example, injured pinnipeds may 

be entangled in gillnets and also show evidence of gunshot wounds. Where multiple causes of 

injury or death are reported by stranding coordinators and the primary cause of death (i.e., 

gunshot or gillnet entanglement) is unknown, we have reported a combined cause in tabular and 

descriptive summaries. 

Prorating of serious injuries (large whales only)

 Large whales may provide the opportunity to track outcomes of human-caused injuries, 

due to the ability to recognize and resight individuals over time. In addition to ‘NSI’ and ‘SI’ 

categories, a third category of prorated serious injury (‘SI prorate’) is used for large whales. 

Prorated SI categories are determined from large whale records where the outcome is known, 

based on a review of historical large whale injury cases (NMFS 2012b). For example, 25 large 

whale cases with vessel-strike lacerations with known outcomes were reviewed and 13 (52%) 

resulted in a decline in health status or death of the animal (NMFS 2012b). These data are used 

to inform decision-making on current vessel-strike lacerations where the severity of the 

2
laceration (superficial versus deep) is unknown and the vessel’s size and speed are unknown. 

For these cases, SI is prorated by 0.52 to reflect the known outcomes of the 25 cases with vesselstrike lacerations. For cases where sufficient detail is available on the severity of the vesselstrike laceration, other SI codes are applied. If a laceration is superficial and does not extend 

below the blubber layer, this is considered a NSI. If the laceration extends below the blubber 

layer (deep), the whale is considered seriously injured (equivalent to an SI prorate value of 1.0). 

An example of calculating annual human-caused SI and mortality for large whales as part of the 

SAR process might include 10 documented vessel-strike lacerations of large whales of unknown 

severity, where the vessel’s size and speed are unknown. Ten large whales with lacerations of 

unknown severity are counted as 10 x 0.52 = 5.2 cases of SI. If one of these cases were 

confirmed as a deep laceration, then the calculation would be 9 x 0.52 = 4.7 + 1.0 = 5.7 cases of 

SI. 

Results

 A total of 1,501 human-related injury and mortality records are summarized by 

anthropogenic source in Table 1 and Appendix 4. Approximately 80% of all records represent 

opportunistic reports of animals stranded on beaches or at-sea sightings. Only 273 records were 

derived from systematic observations, either fishery observer programs (n=136), monitored 

research-related activities (n=83), or removals of pinnipeds from the Bonneville Dam area under 

MMPA Section 120 (n=54). Approximately 60% of all records involved animals initially found 

dead (Table 2). Pinnipeds (n=1,211) were most commonly injured or killed by human-related 

activities, followed by large whales (n=117) and small cetaceans (n=173) (Tables 3-5). The 

primary cause of documented serious injury or mortality for pinnipeds was hook and line fishery 

interactions (Table 6). Large whale serious injury and mortality was most commonly linked to 

vessel strikes (Table 6). Serious injury and mortality of small cetaceans was documented most 

frequently in scientific research trawls (Table 6). Live animals accounted for 843 records, 

which were evaluated and assigned SI/NSI determinations, including 750 pinnipeds, 82 large 

whales, and 11 small cetaceans (Tables 7a-c). 

The primary causes of pinniped injury and mortality were hook and line fishery 

interactions (n=297), shootings (n=212), and entrainment into power plant water intakes (n=142) 

(Tables 3 and 6, Appendix 4). Pinniped injury and mortality records included California sea 

lions (Zalophus californianus) (n=891), harbor seals (Phoca vitulina) (n=230), northern elephant 

seals (Mirounga angustirostris) (n=40), Guadalupe fur seals (Arctocephalus townsendi) (n=20), 

northern fur seals (Callorhinus ursinus) (n=17), and unidentified pinnipeds (n=13) (Table 2). 

Most pinniped injury cases involved human intervention and treatment, either in the field or 

through capture and subsequent care at a rehabilitation facility. Many pinnipeds (n=245) were 

successfully treated and released from rehabilitation facilities, and it is assumed that they 

survived following treatment. Therefore their final injury assessments were NSI. Some 

pinnipeds were treated and released on site, and their final injury status was case-specific. A 

number of pinnipeds were euthanized as a result of their injuries (n=81), while others were sent 

to public display facilities (n=17) because their existing post-treatment condition made survival 

in the wild unlikely or they were individuals targeted for removal to protect endangered salmon. 

Including the 81 euthanized pinnipeds, 290 died of their injuries and another 98 were released 

with serious injuries. Pinniped records lacking detail regarding whether the animal was released 

following rehabilitation facility care were determined to be seriously injured. Initial NSI 

determinations were made for 154 pinnipeds; of these, 19 (12%) later died (Table 7a), which 

reflects that some pinniped injuries are misclassified because the severity of injuries are not fully 

realized until post-mortem examination (see Discussion). 

 A total of 117 large whale injury and mortality records were reviewed (Tables 2 and 4). 

Of these, 35 were dead and the remaining 82 records were assessed for NSI/SI (Table 7b). 

Vessel strikes were the most common form of injury to gray, blue (Balaenoptera musculus), and 

3
fin (Balaenoptera physalus) whales, while entanglement in pot/trap fisheries was the most 

common source of injury to humpback whales (Megaptera novaeangliae) (Table 6). Injured 

large whales included humpback whales (n=22), gray whales (n=31), unidentified whales 

(n=17), fin whales (n=4), minke whales (Balaenoptera acutorostrata) (n=2), sperm whales 

(Physeter macrocephalus) (n=1), and blue whales (n=1) (Table 2), with vessel strikes and 

entanglement-related injuries as the most common causes of SI and mortality (Table 6). Of 82 

large whales evaluated for NSI/SI, 65 cases were fishery-related entanglements, 15 cases 

involved vessel strikes, and 2 cases involved entanglement in marine debris. Only a small 

fraction of the large whale injury cases (n=17) involved human intervention to remove gear. 

This reflects that many entangled whales are seen only once or that weather conditions prevent 

safe disentanglement attempts. Four large whale records that were initially designated as SI 

resulted in a final injury status of NSI, as a result of successful disentanglement efforts or the 

animal becoming free of gear over time. Thirty-seven other large whale records with initial SI 

designations retained final injury designations of SI and three whales were later found dead 

(Table 7b). One gray whale initially seen in July 2009 with constricting gillnet and rope cutting 

into its caudal peduncle was assigned an SI status and was resighted in 2010 and 2011, still 

entangled. This whale was resighted in 2013, free of gear and in apparent good health, thus the 

final injury determination for this case was non-serious. 

 Small cetaceans were rarely assessed for SI (n=11) because most were initially reported 

as dead (n=162). Mortality in gillnets and unidentified net fisheries accounted for approximately 

half of the small cetacean records (n=82), with about half of all entanglement records derived 

from fishery observer programs (n=38). Research-related entanglements in scientific trawls or 

nets accounted for 46 small cetacean records. Small cetaceans assessed for injury severity 

included Pacific white-sided dolphins (Lagenorhynchus obliquidens) (n=6), bottlenose dolphins 

(Tursiops truncatus) (n=2), harbor porpoise (Phocoena phocoena) (n=2) and long-beaked 

common dolphin (Delphinus capensis) (n=1). (Table 2). Entanglement-related injuries were 

responsible for all small cetacean injuries, with research-related activities accounting for all the 

Pacific white-sided dolphin injuries. Human intervention resulted in one Pacific white-sided 

dolphin being freed from survey equipment without serious injuries, and one harbor porpoise 

was released from a research net without serious injuries. Of the 11 small cetacean records 

assessed for injuries, 2 animals died, 2 were considered non-serious injuries, and the remaining 7 

records were determined to be serious injuries (Table 7c). Four deaths of long-beaked common 

dolphins were documented in 2011, as a result of exposure to underwater detonation exercises 

(Danil and St. Leger 2011). 

Discussion

Most records of human-related marine mammal injuries and deaths represent 

opportunistic reports obtained through stranding networks and at-sea sightings. Stranding 

network data should be considered as a minimum measure of human-related injury and mortality 

because not all carcasses come ashore or are detected. Where evaluated, estimates of detection 

rates of cetacean carcasses are consistently quite low across different regions and species (<1% 

to 17%), highlighting that observed numbers are not representative of true impacts (Kraus et al. 

2005, Perrin et al. 2011, Williams et al. 2011, Prado et al. 2013). Not all human-related impacts 

are considered here, such as military sonars and other anthropogenic sounds that may impact 

beaked whales and whose effects would be difficult to recognize unless affected animals 

stranded (Cox et al. 2006). 

Variability in the assessment and determination of human-related injuries and mortality 

by responder or region is an unavoidable situation because data-recording standards may differ 

and the ability to thoroughly examine animals may be compromised by weather or accessibility 

to carcasses (Moore et al. 2013). We have made an effort to choose only records that have 

4
unequivocal or probable human-related causes and recognize that some cases may be missed 

because of a failure to recognize human-caused injuries and deaths. 

Many serious injuries and deaths attributed to marine debris involve derelict fishing gear 

that cannot be associated with a specific fishery, or in some cases, gear originates from outside of 

U.S. waters (three northern fur seals were found dead in netting of Chinese origin in 2009). 

Impacts of commercial fisheries that utilize nets, pots, and traps are likely greater than the 

number of observations because derelict gear can entangle animals for long periods. Explicit 

examples include ghost netting that contained harbor seal carcasses of varying states of 

decomposition, demonstrating that the net had entangled animals over a long period of time. 

A small percentage of pinnipeds (12%) died after an initial injury assessment of NSI. 

Nearly all of these animals died during treatment in rehabilitation facilities, with hook-related 

injuries that appeared superficial (hooks in flippers and/or lip). Post-mortem examinations often 

revealed causes of death that were unrelated to the visible injury. For example, a California sea 

lion with a hook in its back was found during necropsy to have sharp fragments of plastic in its 

stomach. Other cases involved embedded bullets found post-mortem or hooks in the 

esophagus/stomach, which were not suspected during initial examination of the animal.

TABLE 3: Summary of Pinniped1 Injury Categories and Criteria

Instructions: Each pinniped injury event is recorded to the appropriate injury/information category using all available 

information and scientific judgment, as described in the Procedural Directive. For a single injury event to which several 

categories apply, the injury determination with the highest level of severity is assigned. More detailed information or 

extended observation on an individual case/animal may justify a determination differing from the guidance of this table. Any 

injury leading to apparent significant health decline (e.g., skin discoloration, fat loss) is a serious injury.

Category Injury/Information Injury 

Determination2

Additional factors for evaluating 

whether “case specific” injuries are 

serious or non-serious (additional 

factors at end of table) *

P1

P5c Hook(s) in any body part, but hook(s) is 

removed or pulls out Case specific 

Prolonged restraint or struggle that could 

lead to capture myopathy, location of 

hooking on the body, depth of hook, hook 

pulls out cleanly vs. causes further injury 

during dehooking, method used to remove

1 For the purposes of this table, pinnipeds include all pinniped species except walrus.

2

 This table includes on only those criteria determined to be serious injuries or case specific based on expert opinion at the 2007 Workshop 

(Andersen et al., 2008) and by pinniped experts on the NMFS Determination Staff working group. For the purposes of streamlining the 

information for the reader, criteria determined to be non-serious injuries are not included in this table. 3 SI = serious injury. 4 For the purposes of this table, gear is defined as any portion of fishing gear excluding the hook, which is considered separately. Lures are 

considered gear. Gear also generally refers to any type of debris entangling or attached to the animal.

5 Case specific = Could be a serious or non-serious injury, but either 1) there insufficient information about the impact of a particular injury, 

or 2) additional factors must be considered on a case-by-case basis to determine the severity.

Appendix 1. Pinniped Injury Criteria (NOAA 2012) 15
P5d

Hook(s) in appendage or body (excluding 

criteria P5a-c and P12), without trailing 

gear or with trailing gear that does not

object or body cavity exposure

6 For the purposes of this table, potential as it relates to criterion P5d indicates that the trailing gear IS NOT capable of leading to any of the 

situations listed.

7 NSI = non-serious injury. 8 For the purposes of this table, potential as it relates to criterion P6 indicates that the trailing gear IS capable of leading to any of the 

situations listed.

9 For the purposes of this table, “trauma” is defined as a wound or bodily harm caused by an extrinsic agent. Blunt trauma is an injury 

(abrasion, laceration, contusion or skeletal fracture) produced by a blunt object striking the body or impact of the body against a blunt object 

or surface. Sharp force trauma is an injury caused by a sharp or pointed object or a bullet from a gunshot creating a penetrating (stab, chop or 

incision) wound. Laceration is defined as a ragged incision or a tearing of the skin. Lacerations are caused by blunt trauma that results in 

stretching, tearing, crushing, shearing, or avulsion of the tissue. 10 For the purposes of this table, “penetration” is defined as a wound occurring when a foreign object punctures the body, such as a bullet 

from a gunshot. Penetrating wounds can be characterized as one of three types: stab (small external wound that is greater in length into the 

body than is apparent on the skin surface), incised (clean cuts into the skin which are longer on the skin surface than they are deep), or chop 

wounds (incised wounds that penetrate deep to the bone, leaving a groove or cut in the bone). 

Appendix 1. Pinniped Injury Criteria (NOAA 2012) 16
P13 Partially severed or fractured flipper(s) Case specific

Cleanliness (clean cut vs. tear), nature of 

injury causing the loss, extent of fin or 

flipper loss, opened or closed fracture, 

dislocation, amount/duration of blood loss

P14

Dependent animal (i.e., pup, juvenile) 

released alone post-interaction or 

dependent animal left with a seriously 

injured or dead mother

SI

P15 Observed or reported collision with vessel Case specific

Speed of vessel, size of vessel, hull shape, 

part of vessel to strike the animal (e.g., 

propeller, hull), size of animal compared to 

size of vessel, location of strike on animal’s 

body, extent and location of wound(s) to 

animal

* Factors listed in the far right column of Table 3 are unique to the associated injury type. In addition to those listed in this column, the 

factors that should be considered, if available, when reviewing all case specific injury events in Table 3 include, but are not limited to: 

- Species

- Age or age class (e.g., calf, juvenile, 

adult)

- Sex

- Size of animal

- Overall health (e.g., nutritional 

status, body condition, pre-existing 

disease state, pre-existing injuries)

- Behavior during and/or after injurycausing interaction (e.g., listlessness)

- Reproductive status (e.g., pregnant, 

lactating, has dependant pup)

- Natural history (e.g., small home 

range, large home range)

- Location of injury (e.g., mouth, 

head, body, flipper/fin, internal)

- Size of injury

- Duration of injury (e.g., single event, 

repeated, chronic)

- Depth of injury (e.g., superficial or 

to the bone, penetrating muscle or 

organs)

- Cleanliness of injury (e.g., 

compression, tearing)

- Environmental condition (e.g., 

individuals out of their normal 

habitat, environmental stressors)

- Social stressors (e.g., social structure 

of species, separation of social 

individuals from the group, 

mother/pup separation)

- Cumulative effects of repeated 

exposures

- Compounding effects of multiple 

injuries obtained during a single 

event

- Availability of data on multiple 

sequential events involving the same 

individual over time

- Susceptibility of the species to 

capture myopathy (some sensitive, 

others robust, some unknown)

- Ability of rehabilitated animal to be 

released

- Relative effect of blood loss on 

different species

In addition to those factors listed above, the factors that apply to all fishery or marine-debris interaction related case specific injuries include, 

but are not limited to:

- Entanglement type (e.g., hooked, 

anchored, entrapment)

- Amount and size of gear(e.g., size, 

length and number of lines; number 

of buoys, traps or anchors; volume 

of netting; material of gear) 

- Entanglement constriction (e.g., 

tight, loose, multiple wraps)

- Habitat where animal is located 

(e.g., an animal with trailing gear in 

areas of dense gear or an area with 

vegetation or on shore is more likely 

to risk snagging the gear and 

becoming anchored)

- Entanglement duration

- Existence, type and amount of any 

trailing gear

- Method of handling the animal 

during disentanglement

Appendix 1. Pinniped Injury Criteria (NOAA 2012) 17
TABLE 1: Summary of Large Cetacean1 Injury Categories and Criteria

Instructions: Each large cetacean injury event is recorded to the appropriate injury/information category using all 

available information and scientific judgment, as described in the Procedural Directive. Criteria L10 - L12 

accommodate events that lack details necessary for assignment to a more specific category. For a single injury 

event to which several categories apply, the injury determination with the highest level of severity is assigned. More 

detailed information or extended observation on an individual case/animal may justify a determination differing 

from the guidance of this table. An animal that is fully disentangled would generally be considered not seriously 

injured, unless there is additional evidence of a serious injury. Any injury leading to apparent significant health 

decline (e.g., skin discoloration, lesions near the nares, fat loss, increased cyamid loads) is a serious injury.

Category Injury/ Information Injury 

Determination Criteria

L1 Ingested gear2 or hook(s) SI3 Swallowed, not simply draped through 

mouth

L2 Constricting wrap SI

Tightly wrapped line anywhere on body that 

indents the skin or does not shift with 

whale's movement, or line that is likely to 

become constricting as the whale grows. 

Indication that a whale that is heavily 

weighted, anchored or has a discolored 

appendage is sufficient evidence of 

constricting gear

L3 Loose wrap, bridled or draped gear NSI4

Loosely wrapped gear that moves or shifts 

freely with whale's movement. Absence of 

constricting gear must be confirmed

L4 External hook NSI Fishing hook of any size on any part of the 

body (i.e., not ingested)

L5a Deep laceration5 SI

Laceration with the potential to affect major 

artery (e.g., laceration or severing at 

insertion of flipper/fluke), penetrating body 

cavity, or cutting bone

L5b Superficial laceration NSI Laceration not deeper than blubber layer, 

does not affect major artery, or cut bone

L6a Vessel much greater in size than 

whale or vessel ≥65' and >10 knots SI

Struck by vessel much greater in size than 

the whale and traveling greater than 10 

knots, or struck by vessel equal or greater 

than 65' and traveling greater than 10 knots,

and no information on injury to the whale

L6b Vessel smaller in size than whale 

or vessel <65' and >10 knots Prorate6

Struck by vessel smaller in size than the 

whale and traveling greater than 10 knots, or 

struck by vessel less than 65' and traveling 

greater than 10 knots, and no information on 

injury to the whale. A strike to a calf by a 

vessel of any size and traveling greater than 

10 knots will be considered a serious injury 

: 0.20

1 For the purposes of this table, “large cetaceans” include all mysticetes and sperm whales.

2 For the purposes of this table, “gear” is defined as any portion of fishing gear excluding the hook, which is considered separately. 3 SI = Serious Injury. 4 NSI = Non-Serious Injury. 5 For the purposes of this table, “laceration” is defined as a ragged incision or a tearing of the skin. Lacerations are caused by trauma that 

results in stretching, tearing, crushing, shearing, or avulsion of the tissue. Trauma, including blunt and sharp force trauma, includes a wound 

or bodily harm caused by an extrinsic agent. 6

 “Prorate” means the number of events assigned to a given category within the assessment period is multiplied by the prorate number 

provided for that category.

certainty

L11 Vessel strike laceration Prorate: 0.52

Whale confirmed with non-entanglement 

related laceration but lacking details to place 

in either criteria L5a or L5b with a high 

degree of certainty. Includes observation of 

blood in water

L12 Vessel strike observed Prorate: 0.36

Confirmed vessel strike report where there 

is insufficient detail to assign event to 

criteriaL6a – L7b with a high degree of 

certainty. A strike to a calf by a vessel of 

unknown size traveling at an unknown 

speed will be considered a serious injury

7 “Dependent” for a large cetacean means a non-weaned calf. Weaned calves and juvenile large cetaceans are no longer dependent on their 

mothers.

TABLE 2: Summary of Small Cetacean1 Injury Categories and Criteria 

Instructions: Each small cetacean injury event is recorded to the appropriate injury/information category using all available 

information and scientific judgment, as described in the Procedural Directive. For a single injury event to which several 

categories apply, the injury determination with the highest level of severity is assigned. More detailed information or 

extended observation on an individual case/animal may justify a determination differing from the guidance of this table. 

Any injury leading to apparent significant health decline (e.g., skin discoloration, fat loss) is a serious injury.

Category Injury/Information Injury 

Determination2

Additional factors for evaluating 

whether “case specific” injuries are 

serious or non-serious (additional 

factors at end of table) *

S1

A free-swimming animal observed at a 

date later than its human interaction, 

exhibiting signs of declining health 

believed to be resulting from initial injury 

(e.g., a marked skin discoloration, fat loss)

SI3

S2 Ingested gear4 or hook(s) SI

S3 Visible blood loss Case specific5 Amount of blood, location of the bleeding 

injury, duration of bleeding

S4

Animal brought on vessel deck following 

entanglement/entrapment (excluding 

scientific research targeting marine 

mammals and authorized as such under a 

NMFS scientific research permit, where 

the animal is brought on and placed on the 

vessel deck in a controlled manner)

SI 

S5a 

Hook(s) in head (excluding criterion S5b), 

regardless of the presence of gear SI 

S5b Hook(s) confirmed in lip only, external 

tissue outside of teeth, no trailing gear Case specific

Prolonged restraint or struggle that could 

lead to capture myopathy, size of hook, 

depth of hooking, impairing ability to feed, 

presence of other injuries

S5c Hook(s) in any body part, but hook(s) is 

removed or pulls out Case specific

Prolonged restraint or struggle that could 

lead to capture myopathy, depth of hook, 

hook pulls out cleanly vs. causes further 

injury during dehooking, method used to 

remove hook, length of time hooked

S5d

Hook(s) in appendage or body (excluding 

criterion S5a), without trailing gear or with 

trailing gear that does not have the 

potential6

Case specific to: 1) become a constricting 

wrap on animal; 2) be ingested; 3) 

accumulate drag; or 4) become snagged 

on something in the environment, 

anchoring the animal

Prolonged restraint or struggle that could 

lead to capture myopathy, depth and 

location of hook, type and amount of gear 

attached

1 For the purposes of this table, small cetaceans include all odontocetes except sperm whales.

2

 This table includes on only those criteria determined to be serious injuries or case specific based on expert opinion at the 2007 Workshop 

(Andersen et al., 2008) and by small cetacean experts on the NMFS Determination Staff working group. For the purposes of streamlining the 

information for the reader, criteria determined to be non-serious injuries are not included in this table. 3 SI = serious injury. 4 For the purposes of this table, gear is defined as any portion of fishing gear excluding the hook, which is considered separately. Lures are 

considered gear. Gear also generally refers to any type of debris entangling or attached to the animal.

5

 Case specific = Could be a serious or non-serious injury, but either 1) there is insufficient information about the impact of a particular 

injury, or 2) additional factors must be considered on a case-by-case basis to determine the severity 6 For the purposes of this table, “potential” as it relates criterion S5d indicates that the trailing gear IS NOT capable of leading to any of the 

situations listed.

Appendix 3. Small cetacean injury criteria (NOAA 2012). 20
S6 

Gear attached to free-swimming animal 

with potential7

SI

to: 1) become a constricting 

wrap on animal; 2) be ingested; 3)

associated injury (i.e., where directly or 

indirectly caused by initial entanglement), 

response of individual animal, method 

used by human to remove gear from 

animal

S8a

Gear wrapped and constricting on any 

body part or is likely to become 

constricting as the animal moves or grows

SI

S8b Gear wrapped and loose on any body part Case specific

Gear type, amount of gear, potential for 

snag, potential to lead to criterion S8a, 

animal body size relative to gear (e.g., 

because of species or age), effect on 

animal movement, species sensitivity (e.g., 

frightens easily)

S9 Body trauma8

Case specific not covered by any other 

criteria

Location of wound, depth (e.g., superficial 

or to the bone, penetrating muscle or 

organs), length, number of lacerations, 

cleanliness (i.e., compression vs. tearing)

S10

Visible fracture(s), excluding pectoral fins 

(see criterion S13d for pectoral fin 

fractures)

SI

S11 Vertebral transection, including fully 

severed flukes SI 

S12 Body cavity penetration9

SI by foreign object 

or body cavity exposure 

S13a Loss or disfigurement of dorsal fin Case specific

Cleanliness (i.e., compression vs. tearing), 

nature of injury causing the loss, extent of 

fin loss (i.e., full or partial), amount and 

duration of blood loss

S13b Partially severed flukes, transecting 

midline SI 

7 For the purposes of this table, potential as it relates criterion S6 indicates that the trailing gear IS capable of leading to any of the situations 

listed.

8 For the purposes of this table, “trauma” is defined as a wound or bodily harm caused by an extrinsic agent. Blunt trauma is an injury 

(abrasion, laceration, contusion or skeletal fracture) produced by a blunt object striking the body or impact of the body against a blunt object 

or surface. Sharp force trauma is an injury caused by a sharp or pointed object creating a penetrating (stab, chop or incision) wound. 

Laceration is defined as a ragged incision or a tearing of the skin. Lacerations are caused by blunt trauma that results in stretching, tearing, 

crushing, shearing, or avulsion of the tissue. 

9 For the purposes of this table, “penetration” is defined as a wound occurring when a foreign object punctures the body. Penetrating wounds 

can be characterized as one of three types: stab (small external wound that is greater in length into the body than is apparent on the skin 

surface), incised (clean cuts into the skin which are longer on the skin surface than they are deep), or chop wounds (incised wounds that 

penetrate deep to the bone, leaving a groove or cut in the bone). 

Appendix 3. Small cetacean injury criteria (NOAA 2012). 21
S13c Partially severed flukes, not transecting 

midline Case specific

Cleanliness (i.e., compression vs. tearing), 

nature of injury causing the loss, amount 

and duration of blood loss

S13d Partially or completely severed or 

fractured pectoral fin(s) Case specific

Cleanliness (i.e., compression vs. tearing), 

nature of injury causing the loss, extent of 

fin loss (i.e., full or partial), amount and 

duration of blood loss, opened or closed 

fracture

S14

Social animal separated from group and/or 

released alone post-interaction (excluding 

criterion S15)

Case specific

Species (e.g., sensitivity, offshore vs. 

inshore), location of release (e.g., 

likelihood of animal locating its 

conspecifics) 

S15

Dependent animal (i.e., calf, juvenile) 

released alone post-interaction or 

dependent animal left with a seriously 

injured or dead mother

SI 

S16 Observed or reported collision with vessel Case specific

Speed of vessel, size of vessel, hull shape, 

part of vessel to strike the animal, size of 

animal compared to size of vessel, 

behavior of animal after collision, extent 

and location of wound(s) on animal

* Factors listed in the far right column of Table 2 are unique to the associated injury type. In addition to those listed in this column, the 

factors that should be considered, if available, when reviewing all case specific injury events in Table 2 include, but are not limited to: 

- Species

- Age or age class (e.g., calf, juvenile, 

adult)

- Sex

- Size of animal

- Overall health (e.g., nutritional 

status, body condition, pre-existing 

disease state, pre-existing injuries)

- Behavior during and/or after injurycausing interaction (e.g., dorsal 

arching, listlessness)

- Reproductive status (e.g., pregnant, 

lactating, has dependant calf)

- Natural history (e.g., indigenous, 

migratory)

- Location of injury (e.g., mouth, 

head, body, fin, tail, internal)

- Size of injury

- Duration of injury (e.g., single event, 

repeated, chronic)

- Depth of injury (e.g., superficial or 

to the bone, penetrating muscle or 

organs)

- Cleanliness of injury (e.g., 

compression, tearing) 

- Environmental condition (e.g., 

individuals out of their normal 

habitat, climate stressors)

- Social stressors (e.g., social structure 

of species, separation of social 

individuals from the group, cow/calf 

separation)

- Cumulative effects of repeated 

exposures

- Compounding effects of multiple 

injuries obtained during a single 

event

- Availability of data on multiple 

sequential events involving the same 

individual over time

- Susceptibility of the species to 

capture myopathy (spinner dolphins 

and porpoises notoriously sensitive; 

bottlenose dolphins robust; many

others fall in between, with some 

unknown)

- Ability of rehabilitated animal to be 

released

- Relative effect of blood loss on 

different species

In addition to those factors listed above, the factors that apply to all fishery-interaction related case specific injuries include, but are not 

limited to:

- Entanglement type (e.g., hooked, anchored, entrapment)

- Amount and size of gear (e.g., size, length and number of 

branches of line; number of buoys, traps or anchors; volume 

of netting)

- Entanglement constriction (e.g., tight, loose, multiple wraps)

- Habitat where animal is located (e.g., an animal with trailing 

gear areas of dense gear or an area with vegetation is more 

likely to risk snagging the gear and becoming anchored)

- Entanglement duration

- Existence, type and amount of any trailing gear

- Method of handling the animal during disentanglement

HOOKING OFFSHORE CA NSI

A CALIFORNIA SEA LION WAS HOOKED IN THE LIP DURING 

THE SHARK LONGLINE SURVEY AND WAS BROUGHT TO THE 

VESSEL IN EXCELLENT CONDITION. BECAUSE IT WAS VERY 

ACTIVE, FOR THE SAFETY OF THE CREW AND SCIENTISTS, 

THE ANIMAL WAS NOT RAISED OUT OF THE WATER ON THE 

SHARK CRADLE TO REMOVE THE HOOK. RATHER A LONG 

HANDLED CUTTER WAS USED TO CUT THE LEADER AS CLOSE 

TO THE ANIMAL AS POSSIBLE, WITHIN LESS THAN ONE 

FOOT FROM THE HOOK. THE TIME AT WHICH THE SEA LION 

WAS BROUGHT TO THE VESSEL AND RELEASED WAS 00:40 

GMT. THE SEA LION SWAM AWAY VIGOROUSLY. WHILE THE 

SEA LION DID NOT APPEAR TO BE OTHERWISE INJURED, THE 

INFORMATION ABOVE INDICATES IT WAS RELEASED 

INJURED DUE TO THE HOOK. THE HOOKS USED ARE NOT 

STAINLESS AND THE EYE WILL LIKELY RUST OUT WITHIN 

DAYS DROPPING THE LEADER IF THE HOOK DOES NOT FALL 

OUT FIRST. NSI P5B NA
