AFSC/RACE/SAP/Foy: Effects of ocean acidification on larval Tanner crab: Kodiak Island, Alaska.

To study the effects of ocean acidification we examined the effects of ocean acidification on the larval stages of the economically important southern Tanner crab, Chionoecetes bairdi. 
                Ovigerous females were reared in one of 3 treatments: control (ambient pH ~8.1), pH 7.8, and pH 7.5 for 2 years. Larvae in year 1 were from oocytes developed in the field whereas larvae in year 
                2 were from oocytes developed under acidified conditions. Larvae hatched each year, were also exposed to 3 pH treatments to examine starvation-survival, morphology, condition, and calcium/magnesium 
                content. Approximately 300 larvae were stocked in multiple treatments for testing the effect of pH. Hatching success was measured as the total % of larval hatched from a full clutch while duration 
                was the number of days over which hatching occurred. Hatching success did not differ among treatments in 2012 but varied between 46 to 87% in 2013 dependent on pH treatment. Larval mass was highest 
                in pH 7.8 in 2012 and lowest in the control, however in 2013 the highest larval mass was in the control water. There were only small (not significant) changes in magnesium or calcium content among 
                treatments in 2012 however, the reduction in both minerals at higher pH was greater in 2013. There was higher percent carbon and nitrogen contents in pH 7.5 larvae in 2013. The morphology of Tanner 
                crab larval was assessed from 200 larvae stocked in multiple 2 L beakers. There was no effect of treatment on larval morphometrics. In 2012 and 2013, we examined if embryos developed under acidified 
                conditions affected larval morphology by assessing 15 newly hatched larvae from each treatment. There was again no effect of treatment on larval morphometrics. Starvation survival experiments 
                were performed in 1 L sized PVC inserts. In both years larvae from embryos that developed in pH 7.5 water survived about 3 days longer than those that developed in control water. However, in 2012 
                larvae from embryos that had developed in pH 7.8 water were similar to control larvae whereas in 2013 they were intermediate between the control and pH 7.5 larvae.  The overall effects of treatment 
                at the larval stage appeared to be better condition and initial survival at lower pH, however multiple years of treatment led to lower survival.

AFSC/RACE/GAP/McConnaughey:USBL Proof of Concept-1998-USBL pole drawings

The trials were conducted in Dabob Bay, Washington, in May 1998. The main objective of these trials was to determine an accurate and reliable system to track a fishing trawl. Three USBL vendors were invited and agreed to participate in the trials. Nautronix Ltd. (Nautronix) provided their ATS II system, Simrad Subsea A/S (Simrad) provided their ITI system, and Ocean Research Equipment, Inc. (ORE) submitted their Trackpoint II Plus system. A local ORE distributor, MECCO, Inc. (MECCO), provided and operated the Trackpoint II Plus system. The U.S. Navy?s fixed, underwater tracking range in Dabob Bay, operated by the Naval Undersea Warfare Center (NUWC) Division ? Keyport, Washington, was also used in these trials. The range was used to provide simultaneous sub-sea positioning of the fishing trawl and to serve as a benchmark for system evaluations. The U.S. Navy also provided surface navigation support for the fishing vessel during these trials. The vessel selected by AFSC to conduct these trawls was the F/V Vesteraalen. It is 124 feet long, has a beam of 32 feet, and a draft of 18 feet. The F/V VESTERAALEN has a single, fixed-pitch propeller with a nozzle. By design, the vessel is like most in-shore trawlers and has, in fact, operated in Alaska in the past. The tests were conducted using NMFS otter trawls, typically used in Alaskan waters. A trial schedule was developed that would provide each vendor with three days to mobilize and test their systems. Each vendor?s equipment was attached to the fishing trawl, along with the U.S. Navy tracking gear. Both the U.S. Navy and the USBL vendor collected simultaneous trawl position data as determined by their respective equipment, with the trawl being dragged on the bottom along a predetermined track. The main objective of these trials was to assess the accuracy of each vendor?s equipment. This was accomplished using a statistical comparison between each vendor?s data and the U.S. Navy?s data that were observed simultaneously. This report details the results of these trials and summarizes the comparison results. It also contains details of the equipment and the methodologies used to collect and analyze the data. As a result of the data analysis, conclusions were drawn and recommendations have been included in this report.

AFSC/RACE/GAP/McConnaughey: Fishpac Projects-2008-Seaboss-Stills

The broad scope of the Essential Fish Habitat (EFH) mandate requires an efficient process for describing and mapping the habitat needs of federally managed species.  For example, research indicates surficial sediments affect the distribution and abundance of many groundfish species, yet traditional sampling with grabs and cores is impractical over areas as large as the Bering Sea shelf.  Acoustic tools are suitable for large-scale surveying and show great promise as a substitute for direct-sampling methods, but they have not been proven useful for EFH purposes.

AFSC/NMML: Known human-caused marine mammal injury and mortalities from 2007 to present

The National Marine Fisheries Service (NMFS) is required under the MMPA to estimate the annual human-caused mortality and serious injury of marine mammal stocks by source. Data from documented interactions between humans and Alaska pinnipeds and cetaceans under the jurisdiction of the NMFS are compiled in this data set and details regarding each human/marine mammal interaction are reviewed for evidence of human-caused injury or mortality.  Criteria are applied in order to assign injuries to categories and determine the severity (serious or non-serious). Injury determination details regarding the injury source, type, and severity are included, along with the injury category and criteria supporting the determination. Mortality and injury values are assigned (0, 1, or prorated) to each event for comparison with the calculated Potential Biological Removal levels for each stock.

Description of Specimens in the Marine Mammal Osteology Reference Collection

The NMFS Alaska Fisheries Science Center National Marine Mammal Laboratory (NMML) Marine Mammal Osteology Collection consists of approximately 2500 specimens (skulls and post-cranial skeletons) from 43 species of marine mammals from around the world. Specimens have been collected for life history studies over the past 60 years on projects ranging from pelagic sealing in the 1950s, to collections of marine mammals taken incidentally in commercial fisheries, and those found dead on beaches and rookeries from Alaska to the Antarctic.

The NMML Osteology Collection also houses vast numbers of teeth, primarily from northern fur seals taken during the commercial and subsistence harvests on the Pribilof Islands, Steller sea lions taken incidentally in the Alaska fisheries, and sperm whales collected from Pacific coast whaling stations in the 1950s and 60s. The majority of these teeth were initially collected for aging, but many have been used in recent years in stable isotope, nursing and growth layer\growth index studies.

This database is an inventory of specimens and associated data contained within the osteological collection.

Marine Mammal Food Habits Reference Collection, 1995-2018

The Marine Mammal Laboratory (MML) Food Habits Reference Collection, containing over 1000 specimens of cephalopod beaks and fish bones and otoliths, is used to identify undigested prey remains found in scats or stomachs of stranded or incidentally taken pinnipeds and cetaceans. Marine mammal food habits data are used in conjunction with satellite telemetry and dive records to better understand foraging behavior and prey selection. This information is critical to understanding how commercial fisheries and changing environmental conditions impact these animals.

The Food Habits Collection includes fish and cephalopod species that are commonly consumed by pinnipeds along the Pacific Northwest coast and in Alaska, but we are in the process of adding other potential prey species and specimens to fill unrepresented size ranges.  We are very appreciative of NMFS/AFSC/RACE fisheries biologists, the Alaska Department of Fish and Game and the University of Washington for their ongoing donations to our collection.  With the help and cooperation of researchers such as these, our collection continues to grow in size and usefulness.

The Marine Mammal Food Habits Reference Collection is an important research tool within NMML, and is also used several times a year by graduate students and researchers from universities, government agencies and private institutions.  These collections have contributed to food habits research on Magister armhook squid, Northern fulmar, Newells shearwater, Hawaiian petrel, river otters and marine mammals.  The collections are also used by archeologists to identify fish and mammal bones found in Native American middens from Alaska to Mexico. 

The database is comprised of a table detailing specimens and associated data and measurements for fish and cephalopod soft tissue and hard parts contained within the reference collection.

AFSC/MML/CCEP: Pup production of the California Stock of northern fur seals from 1969 - 2023

The Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) in collaboration with Point Blue Conservation Science initiated long-term studies to determine pup abundance of the California Stock of northern fur seals. The California Stock is comprised of northern fur seals inhabiting San Miguel Island (and Castle Rock, and islet ~1 km northwest) and the Farallon Islands (specifically, Southeast Island) off California. Pup production is the sum of the numbers of live pups and dead pups for a given pupping season. This in turn is used as index to estimate total population abundance. Population abundance is vital to knowing the status of a particular stock or the entire species, as well as knowing what factors are driving population trends. Metadata and datasets corresponding to these studies are reported in Stock Assessment Reports (SAR) for the U.S. Congress and other stakeholders.

AFSC/RACE/GAP/Prescott: Norton Sound Shoreline

We assembled approximately 230,000 National Ocean Service (NOS) bathymetric soundings from 39 lead-line and single-beam echosounder hydrographic surveys conducted from 1896 to 2005 in Norton Sound, Alaska. These bathymetry data are available from the National Geophysical Data Center (NGDC: http://www.ngdc.noaa.gov), which archives and distributes data that were originally collected by the NOS and others. While various bathymetry data have been downloaded previously from NGDC, compiled, and used for a variety of projects, our effort differed in that we compared and corrected the digital bathymetry by studying the original analog source documents - digital versions of the original survey maps, called smooth sheets. Our editing included deleting erroneous and superseded values, digitizing missing values, and properly aligning all data sets to a common, modern datum. We incorporated 3 multibeam surveys, and added an additional 6,992 single-beam soundings from the 2010 Northern Bering Sea bottom trawl survey to fill in where smooth sheet data was lacking. We proofed and digitized 312 cartographic features, comprised mostly of rocks and islets and also digitized 4,305 verbal sediment descriptors, and digitized or adapted 2,142 km of mainland and 837 km of island shoreline.

AFSC/REFM: Isolation by distance (IBD) Alaskan fish stock structure modeling

There is no established management protocol for stocks subject to isolation-by-distance (IBD) stock structure. This study examines several management strategies for two marine fish species subject to IBD using simulation, Pacific cod in the Aleutian Islands (AI) and northern rockfish in the Eastern Bering Sea (EBS) and Aleutian Islands. A one-dimensional stepping stone model was used to model isolation by distance, and was intended to mimic regions where marine species are exploited along a continental shelf. The performance of spatial assessment and management methods depended on how the range was split. Splitting anywhere within the managed area led to fewer demes falling below target and threshold biomass levels and higher yield than managing the entire area as a single unit. Equilibrium yield was maximized when each deme was assessed and managed separately and under catch cascading, in which harvest quotas within a management unit are spatially allocated based upon the distribution of survey biomass. The longer-lived rockfish declined more slowly than Pacific cod, and experienced greater depletion in biomass under disproportionate fishing effort due to lower productivity. Overall, splitting a management area of the size simulated in the model improved performance measures, and the optimal management strategy grouped management units by demes with similar relative fishing effort.
