NOAA Technical Memorandum NMFS 

The National Oceanic and Atmospheric Administration (NOAA) was organized in 1970. It has 

evolved into an agency which establishes national policies and manages and conserves our oceanic 

coastal, and atmospheric resources. It provides managerial, research, and technical expertise to 

produce practical services and essential information for the programs concerned with such resources. 

The National Marine Fisheries Service (NMFS) provides the United States with an integrated 

program of management, research, and services concerned about the protection and rational use of 

living marine resources for their aesthetic, economic, and recreational value. NMFS determines the 

consequences of the naturally varying environment and human activities on living marine resources. 

NMFS provides knowledge and services to foster the efficient and judicious use of those 

resources. NMFS provides for domestic and for international management and conservation of these 

living resources of the sea. 

To carry out its mission, the organization also provides for communication of NMFS information. 

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

informal scientific and technical publications. These documents are specialized reports that require 

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

The management and control of Technical Memorandums has been delegated to the Research Centers, 

Regional Offices, and corresponding staff offices within NMFS. Therefore, requests for copies of 

Technical Memorandums should be sent to the author or to the originating office for the material.

INTRODUCTION

* 

Since passage of the Fishery Conservation and Management Act (FCMA), 

there has been an increasing need for information on the fishing activity 

of foreign vessels in the U.S. Fishery Conservation Zone (PCZ) and other 

areas of U.S. interest. A knowledge of foreign catch and fishing effort 

is essential for analysis of management policies, for appraisal of fishery development potentials, and for planning of fishery surveillance and 

enforcement activities. 

In the case of billfishes, foreign catches in the FCZ are made by 

tuna longline vessels of Japan, Taiwan, and the Republic of Korea. The 

vessels usually direct their effort toward tunas and catch billfishes 

only incidenta1ly.l The primary purpose of this report is to summarize 

available information on the nominal effort and the catch of tunas and 

billfishes by these foreign longline fleets in the FCZ of the central and 

western Pacific during the period 1965-77. 

estimates of the effort and tuna catch by Japanese baitboats fishing around 

IIawaii, Guam, the Northern Marianas, and other U.S. possessions. 

In addition, the report presents 

In the following section the data sources and their characteristics 

and limitations are described. Then the data summarization and estimation 

procedures are discussed. Finally, the tables of resulting catch and 

effort statistics are presented, and suggestions are given for improving 

and updating the information.

Japanese Tuna Longline Statistics by 1" Square 

[Data Set Dl] 

This data set consists of records of Japanese tuna longline nominal 

effort (hooks fished and days fished) and associated catches of tuna and 

billfish species (number of fish) by month and 1' square. It covers only 

those lo squares in the central and western Pacific overlapping the FCZ in 

Hawaii, American Samoa, and Guam, and only the years 1971-75. The data 

are unpublished, and were made available to the National Marine Fisheries 

Service (NMFS) by the Fisheries Agency of Japan. The data were provided 

in unraised form; estimates of total catch and effort in each time-area 

stratum were made by multiplying the sample data by raising factors taken 

from appropriate issues of "Annual Report of Effort and Catch Statistics 

by Area on Japanese Tuna Longline Fishery" published by the Fisheries 

Agency of Japan. 

lUnder the FCMA, the U.S. claims jurisdiction over billfishes in the 

FCZ, but not over tunas.

Japanese Tuna Longline Statistics by 5" Square 

[Data Set D2] 

This data set consists of the well-known published statistics of 

monthly catch and effort by Japanese tuna longliners in 5" square areas. 

It is available throughout the range of the Japanese fleet in the Pacific 

for 1962-77. The data are published in the reference cited above. The 

catch and effort totals for a 5" square are equal to the sum of these 

statistics over all 1" squares in the 5" block, i.e., data set D2 may be 

considered an aggregation of data set D1. 

in raised form since 1967, and unraised form for the earlier years. 

The statistics are published 

Taiwanese Tuna Longline Statistics by 5" Square 

[Data Set D3] 

This data set contains monthly statistics on catch of tunas and 

billfishes (number of fish and weight of fish) and effort (hooks fished) 

of Taiwanese high-seas longliners by 5" square throughout the range of 

the fleet. Data for 1967 through 1977 are available, provided to us by 

the Taiwan Fisheries Bureau. Unraised sample statistics were provided 

by Taiwan and then raised. Annual summaries of the unraised statistics 

and raising factors are published by the Taiwan Fisheries Bureau in 

"Annual Catch Statistics of Taiwan's Tuna Longline Fishery.'' 

American Samoa Tuna Longline Statistics 

[Data Set D4] 

This unpublished data set contains the catch (number of fish) and 

effort (hooks fished and days fished) by sampled Taiwanese, Korean, and 

Japanesri longliners based at Pago Pago and operating primarily in the 

South Pacific. The statistics are extracted from logbooks of daily fishing 

activity submitted by vessel captains to the Office of Marine Resources of 

the Government of American Samoa, and are available for the period 1960 

through 1976.2 The logbook records give daily effort and catch by species 

along with the midday position of the vessel. Not all vessels submit logbooks, so raising factors are necessary to project the sample catch and 

effort to the entire fleet. Computation of raising factors is facilitated 

by a second set of data €or vessels based at Pago Pago. These are the. 

records of cannery landings made available to us by Star-Kist Samoa, Inc. 

and Van Camp Sea Food Co. They provide direct estimates of the tonnage of 

fish landed by all vessels, those appearing in the logbook statistics and 

those not covered in the catch and effort sampling. 

Japanese Baitboat Statistics 

[Data Set D5] 

This data set consists of catch and effort records of the Japanese 

baitboat fleet operating in the central and western Pacific. Catch (in 

metric tons) and nominal effort (vessel days) are published annually by 

2Data for 1977 and 1978 are available, but are incomplete, so catch 

and effort estimates are possible only through 1976.

the Fisheries Agency of Japan in "Annual Report of Effort and Catch 

Statistics by Area, Japanese Skipjack Baitboat Fishery." The published 

records are given by 1" square and 10-day interval. In our analys.is we 

used summaries by month and 1" square for the years 1970-77. On the 

average, the baitboat statistics cover about 80% of the actual catch 

and effort, so we raised the statistics by a factor of 1.25. 

PROCEDURES AND ASSUMPTIONS 

Boundaries 

Figure.1 shows the boundaries we used for computing catch and effort 

within the FCZ around the Hawaiian Islands, American Samoa, Guam, the 

Northern Mariana Islands, and the various minor U.S. possessions, e.g., 

Wake Island, Johnston Atoll, Howland Island, Baker Island, Kingman Reef, 

Palmyra Island, and Jarvis Island. Boundaries are essentially as given 

in the Federal Register (vol. 42(44)-7 March 1977; vol. 43(7)-11 January 

1978), except that we included Kingman Reef as a U.S. territory, and we 

assumed straight-line closures around parts of Jarvis Island, Howland 

Island, and Baker Island. Similarly, we drew a provisional boundary 

(dashed line) around the northern and northeastern part of the American 

Samoa FCZ (including Swains Island) and assumed a median-line separation 

between American Samoa and the Tokelau Islands. 

The provisional boundaries drawn here were adopted to provide a basis 

for catch computations only. 

nor do they prejudice any U.S. position regarding disputed claims or 

jurisdictional conflicts in the Pacific. 

They are not to be construed as legal limits, 

In addition to computing catches of tunas and billfishes and nominal 

effort within each of the 200-mile zones, or within the entire FCZ areas, 

we also computed these statistics for other more restricted zones around 

Hawaii, American Samoa, Guam, and the Northern Mariana Islands (Figures 2, 

3, and 4). The boundaries adopted in these cases were selected primarily 

for illustrative purposes, and are not intended to reflect any preference 

with respect to fishery management policy. For the Hawaiian Islands, the 

chain was split into the main Hawaiian Islands and the Northwestern Hawaiian Islands ("HI), with the dividing line at 161"W longitude (between 

Niihau Island and Nihoa Island). 

50 miles, 100 miles, and 200 miles of the islands in each sector (Figure 2). 

Catches and effort were computed within 

In the case of Guam, the Northern Mariana Islands, and American Samoa, 

a 50-mile zone was drawn and catches and effort were estimated for these 

zones as well as for the entire FCZ (Figures 3 and 4). 

Apportioning 

Estimates of nominal effort and the catch of tunas and billfishes were 

made by adding up the appropriate statistics for all 1" squares or 5" 

squares, or parts thereof, falling within the boundaries of the area of 

interest. In instances where the boundary of an area cut through a square, 

the distribution of catch and effort within the square was assumed to be 

homogeneous, and a part of the square's catch and effort was added to the 

area totals according to the proportion of the square falling within the 

area boundaries. 
4 

One-degree square statistics (D5) were used to estimate effort and 

catch of Japanese baitboat vessels around the Hawaiian Islands, Guam, and 

the Northern Marianas, and other U.S. possessions. One-degree square data 

were also used for Japanese longline catch and effort around Hawaii and 

Guam during 1971-75 (Dl), and for all of the American Samoa longline catch 

and effort estimates (D4).

Coverage of Taiwanese vessels is very low, being generally 

For vessels based at Pago Pago, coverage is variable. From 50 to 95% 

of the vessels landing at Pago Pago submit logbooks containing detailed 

statistics on catch and effort. Since 1970 Korean vessels have been 

covered more completely than longliners from Taiwan, and for vessels of 

both flags the coverage rate has decreased considerably from the levels 

maintained during the 1960's. 

In our initial analyses we computed raising factors for American Samoa 

as the product of (1) estimated average weight, taken from Taiwanese longline data for the area, and (2) ratio of landings by all vessels to landings by those vessels included in the logbook sampling.

adjustment was made assuming the ratio of billfish landings to tuna landings 

was the same at the two canneries. It was done separately for each vessel 

nationality. Next, the adjusted landings were multiplied by other correction 

factors to convert from dressed weights to round weights. These correction 

factors were 1.15 for yellowfin tuna, 1.16 for bigeye tuna, 1.2 for billfishes, and 1.0 for albacore and wahoo. Then,final correction factors were

computed by year, species (except billfishes were combined), nationality, 

and cannery as the ratios of total landings (adjusted as indicated above) 

to the corresponding total numbers of fish caught by the sampled vessels. 

These final factors were multiplied by the individual monthly catches in 

1' cells (D4) and, after apportioning in the manner described above, the 

products were summed within each zone of interest. This procedure was 

followed for billfishes, albacore, yellowfin, bigeye, and wahoo. Thus 

for these species we assumed the total adjusted cannery landings were 

accurate and accounted for all fish caught. The remaining species are 

skipjack and bluefin tunas. These are very minor constituents of the 

catch and are neglected i n t h e canneries' summary statistics. Therefore, 

for these species we estimated total catches in weight by simply multiplying the observed catches in number of fish by estimated average weights of 

6.0 kg (skipjack tuna) and 52.6 kg (bluefin tuna). 

The cannery statistics should account for virtually all tuna and 

billfish taken by the longliners based at Pago Pago, although small amounts 

which are not landed there may go unrecorded. 

Adjustment factors were also used to estimate the total nominal fishing effort by American Samoa longliners. These were computed by nation, 

cannery, and year as the ratio of total vessel days of fishing by all 

vessels covered in the statistics of cannery landings to the number of 

vessel days fished by longliners appearing in the logbook sampling. 

As mentioned in an earlier section, a raising factor of 1.25 was used 

to expand the sample Japanese baitboat catch and effort statistics.

The average weight statistics. 

(1) Average weights for catches in the Hawaiian FCZ and around Johnston 

Atoll were based on annual statistics from the Hawaiian domestic 

longline fleet, provided by the United Fishing Agency, Ltd. of 

Honolulu, Hawaii and the Hawaii Division of Fish and Game (Table 4). P 

(2) The average weights of tunas and billfishes taken elsewhere by 

longliners of Taiwan and Japan were estimated from data obtained 

from the Fisheries Agency of Japan and from publications of the 

Taiwan Fisheries Bureau (Table 5).

Accuracy 

Assuming the basic statistics we used are correct, the accurdcy and 

reliability of our catch and effort estimates depend on two main conditions: 

(1) homogeneity of catch and effort distribution within the smallest spacetime stratum under consideration, and (2) uniformity of sample coverage in 

time and space. 

The first condition does not generally hold, as may be demonstrated by 

comparing estimates based on 5" square data with corresponding estimates 

based on 1' square statistics. 

tics is simply too coarse for an accurate, detailed spatial analysis of 

fishing activity within the FCZ. 

should therefore be viewed circumspectly. 

A 5' breakdown of catch and effort statisEstimates based solely on 5' square data 

Even greater problems are created by departures from the second 

condition. The use of a common ocean-wide raising factor may be perfectly 

adequate for ocean-wide estimates, but may lead to serious distortion in 

estimates of catch and fishing effort in small subareas of the ocean. 

Steps have recently been taken by the Taiwan Fisheries Bureau to improve 

their sampling system so that individual raising factors are available by 

month and 5O square. 

Considering these factors, it is obvious that one cannot put a great 

deal of confidence in some of the catch and effort estimates. Nevertheless, 

these estimates are the best currently available. 

THE CATCH AND EFFORT TABLES 

The estimated nominal effort and catch statistics are presented in 

Tables 6 through 91. Catches are stated in metric tons (mt). Effort is 

given in vessel days. In the case of Taiwan longline effort outside the 

American Samoa area, the effort figures were estimated by dividing the 

number of hooks fished by 2,000, which is approximately the average number 

of hooks fished per vessel day. In other cases effort was computed directly.

than 1 vessel day.

spearfish, since these species are not separated in the records submitted 

by either Japanese or Taiwanese longline fishermen, or in the logbook 

records of foreign vessels based at American Samoa. 

The Japanese baitboat catch estimates are given for albacore, 

yellowfin, bigeye, bluefin, and skipjack. In addition, catches of frigate 

tuna, Auxis thazard, and miscellaneous species (others) are estimated. 

IMPROVING ESTIMATES

We have identified several possible shortcomings in the estimates of 

catch and effort within specified geographical areas. 

be improved by (1) using more detailed longline statistics than the usual 

5" square summaries which are now generally available. 

longline vessels based at Pago Pago daily fishing logs are available to 

us. But the official, published longline statistics of Taiwan, Japan, and 

Korea are only by 5" square. More detailed Japanese data are available in 

unpublished form; (2) using more detailed raising factors, instead of the 

Pacific-wide factors now employed. Taiwan has taken steps to refine this 

aspect of their longline catch estimation--it would be useful if other 

nations also instituted such improvements; (3) using more accurate statistics on average weight. 

into account, and better size statistics should be sought from unpublished 

sources; (4) a more complete analysis of the American Samoa-based fishery. 

The estimates given here reflect only the landings reported by t.he two tuna 

canneries operating in Pago Pago. The records available to us do not take 

into account small amounts of fish landed and sold through other channels. 

A more extensive study of American Samoa fishery statistics should be undertaken so that a complete accounting can be made of all fish caught or landed 

in that area of the FCZ.

fore 

The estimates reported here do not present a complete picture of 

gn tuna and bAlfish catches in the FCZ, since except for American 

Samoa-based vessels no Morean statistics were considered. Koreanotuna 

longliners (mostly sashimi boats) are known to fish in all areas of the 

FCZ, and while extensive catch and effort data are available, we are not 

yet able to answer key questions about appropriate raising factors, sampling 

procedures, and reliability. Until such considerations can be dealt with, 

we will refrain from using the Korean longline statistics. 

In addition to problems with the Korean longline statistics we have 

been unable to evaluate poasible Korean baitboat catches in the FCZ. No 

information is available to us on this subject. 

Mention should be made of fishing inside the Hawaii FCZ by longline 

vessels based in American Samoa. Such catches, mainly by Korean boats, are 

minor, but the frequency of such visits has been increasing in recent years. 

Information on this subject is being compiled for publication in a separate 

report. 

A comment is also needed concerning the possibility that some small 

catch in the American Samoa FCZ is made by longliners not based in Pago 

Pago and therefore not monitored in the American Samoa logbook system. 

Catches by Japanese vessels can be ruled out, since Japanese Government 

statistics show no effort in that area by her vessels since 1971.

But the 

Finally, the published catch and effort records examined in this 

analysis do not cover any Japanese baitboats or longliners under 20 gross 

tons, or any Taiwanese longliners under 50 gross tons. This is of no 

consequence except around Guam and the Northern Marianas, where some small 

Taiwan-based Taiwanese longliners and small Japanese longliners may be 

operating.
