from Canada, Oregon, and California.
Summaries have now been received
Washington reported difficulty in
finding time to compile the results of a large number of tagging cruises,
but a report on completed tagging studies will be submitted by the end of
August.
Considerable discussion was heard concerning the usefulness of
the tagging summaries.
It was generally agreed that the summaries would
be of much value in analyzing the results of each agency's tagging studies.
b.
Status Reports
Tabulated catch data (Appendix B) was received for the trawl
fisheries of California, Oregon, and British Columbia.
Washington reported
that no historical data was readily available but that a submission may be
made next year.
There may be some minor revisions necessary in some of
the catch statistics for earlier years in the California trawl fishery.
These submissions will complete the request for historical data and need
not be resubmitted each year.
c.
Data Series
A suggestion was made to publish catch statistics in the PMFC
trawl data series in metric tons rather than pounds.
Consideration was given to the fact that the fishing industry
is not likely to change to the metric system in the foreseeable future.
Therefore, data in pounds will still be required when dealing with industry.
On the other hand, PMFC and Canadian trawl catch statistics are now
being converted to metric tons for use by INPFC.
It was agreed that it
would be advantageous to publish the series (bottomfish section) in the
metric system but that this action will be deferred until the data input
can be computerized.

PL 88-309:
The Shellfish and Bottomfish Data Analysis Project was
hampered by staff vacancies and problems with availability of suitable cornputers during 1970.
At present, a major undertaking of the project is a co-
operative systems analysis of the Bottomfish program.
National Marine Fisheries Service
Work continued in 1970 on the development of efficient sablefish
"pots," a synopsis of sablefish stocks, survey techniques for spotting
saury, and a pelagic egg and larvae assessment program.
A theoretical yield/recruit study on Pacific ocean perch was undertaken during 1970 to tie in with studies done by Mr. S. Chikuni of the
Fisheries Agency of Japan.
International Pacific Halibut Commission
Because of changes in the trawl fishery, the Halibut Commission
initiated a study to estimate the magnitude of the incidental trawl catch
of halibut off British Columbia.
Results indicated that few halibut were
caught when trawlers were fishing for Pacific ocean perch and that most of
the incidental catch occurred when the trawlers were fishing for lingcod,
Pacific cod, and sole.
Also, catches were largest from May through August--
very few halibut were caught during the winter.
The total amount of halibut
taken incidentally by trawls was estimated to be 3.2 million pounds, split
equally among the three subareas (west coast of Vancouver Island, Queen
Charlotte Sound, and Hecate Strait).
Approximately 30% of the halibut taken
incidentally were below the minimum length of 26 inches.
A special study was initiated during 1970 to obtain information on the
mortality suffered by halibut after they are caught and released by trawlers.
Approximately 16% of the halibut observed were dead when examined and undoubt-

The Canadian catch from the southern stock off the lower
west coast of Vancouver Island (Area 3C) was 318,000 pounds, which was
almost three times the amount taken in 1969 but about the same as the mean
for the 1960-69 period.
Average catch per effort was 108 pounds/hour,
almost twice that in 1969 but still 22% less than the mean for the previous
10 years.

Landings
from the Cape Flattery Spit region within Area 3C (February to April fishery
on deep-water spawning populations) accounted for 165,000 pounds.
