CALL TO ORDER
The seventh annual meeting of the Technical Sub-Committee was
called to order at 0900 hours on June 28, 1966, by Chairman J. Thomson

for the meeting.
-2III.
APPROVAL OF AGENDA
The agenda as circulated prior to the meeting .was approved and
each item discussed consecutively.
IV.
STATUS REPORTS
A change from the format of comparing current catch and effort
with that of the previous 5 years to one of comparison with data of the
previous 10 years was agreed upon by a majority of Sub-Committee members
prior to the meeting.
Therewas discussion on which years should constitute
the 10-year period and how the 10-year mean catch per effort should be
calculated.
The 10-year period, prior to 1965, was agreed. upon as was the
mean C/E of the 10 values for 1955-1964.
1..
Total Catch and Effort for the 1965 Trawl Fishery
The 1965 otter trawl catch by Canadian and United States
fishermen fromnortheastern Pacific waters was approximately 164.8 million
pounds.
This total includes catch from PMFC areas.4A and 4B, Puget Sound
and Strait of Georgia, respectively.
This catch was 21% greater than the
136 million pound catch of 1964 and 25% greater than the mean 10-year
catch of 131.5 million pounds (Table 1).
Total effort increased 2% from 163,012 hours in 1964 to
166,182 hours in 1965.
The catch/effort for all species increased to
992 pounds per hour from the 835 pounds per hour of 1964.
The 1965
catch/effort was also greater than the average for 1955-1964 of 814
pounds per hour (Table 1).
The Alaskan catch by Pacific coast fishermen was negligible
in 1965.
Canada and Washington had record catches of43.9 and 52.8
million pounds, respectively.
The Oregon catch of 33.2 million pounds was
the highest for the past decade, while the California catch of 34.8 million
-3pounds was the highest since 1959.
There were substantial increases in landings of Pacific cod
and Pacific ocean perch, the major individual species for the past few

The bulk of the catch, almost 19 million

In northern Hecate Strait (Area 50) the catch/effort of 1,951

catch/effort of 768 pounds per hour decreased from that of 1964 and was

Analysis of length composition and tag returns suggest that the
recent fishery has been supported principally by the exceptional strong
1962 year class.

Washington fishermen no longer expend enough effort in this area to

Pacific cod landings of 194,000 pounds were 3% lower

In 1965, Pacific ocean perch landings of 31.1 million pounds
increased 42% over those of 1964 and were two and one-half times greater

Oregon fishermen of 14.4 and 13.6 million pounds, respectively, comprised
most of the coastal landings.
The Canadian catch of 3.1 million pounds
and the California catch of 38,000 pounds formed the remainder.
The
recent upward trend in catch/effort established by Washington and Oregon
fishermen was continued.
Canada.
British Columbia trawlers landed a record catch of 3.1
million poutids of Pacific ocean perch.
The 1965 catch taken primarily
from PMFC Areas 5A and SB (Queen Charlotte Sound) was almost three times
that of 1964 and five times the mean catch for 1955-64.
Catch/effort in
1965 for Canadian vessels in Queen Charlotte Sound was about 2,800
pounds per hour.
Washington.
The 1965 Washington catch of 14.4 million pounds
was the highest on record and exceeded the 1964 catch of 11.3 million
pounds by 27%.
The improved catch was made because there were no market
limits imposed during l96E.

Pacific coast Dover sole landings of 16.2 million

Slight decreases in landings were reported by Canada and
Washington.
Oregon landings were down 34% from 1964, while California
landings increased 16% over those of 1964.

it is a major species in landings.

The Dover sole fishery by British Columbia trawlers
continues to be a small-scale operation with 1965 landings of about
0.4 million pounds.
Approximately 50% of the catch vas taken in the
Port San Juan area off the west coast of Vancouver Island (PMFC Area

Exchangof Market Sampling Data (sampj
inventory)
Inventories of market samples had been exchanged along
with status reports among agencies during the past two years.
There
were no problems in this exchange nor any anticipated in the exchange of
specific data on samples.
The exchange of Status Reports was also discussed.
At
Leon Verhoeven's suggestion, all agencies will label their data tables
to avoid confusion in compilations for the Data Series,
3.
Catch/Effort Analysis
The Sub-Committee agreed that the possibilities of
standardizing catch/effort were indeed remote; however, methods of
deriving such data should be clearly definable and similar trends in
catch/effort would be expected for different calculations on mutually
fished stocks.
It was emphasized that absolute values of catch/effort
data of different agencies must be used with caution in view of the
different calculating methods,
Methods in use by the different agencies
are defined in the 1963 Report of the Fourth Annual Meeting of the
Technical Sub-Committee,

otoliths from juvenile and adult ocean perch,
temporarily suspended in 1965 with the resignation of the scientist in
charge of this work0
In 1965, exploratory fishing was conducted in the western
portion of lower Hecate Strait and upper Queen Charlotte Sound (Areas
5C and 5B) with Industrial Development Service funds, which provide for
vessel charter, gear, and the addition of a summer technician and a fulltime term technician to the staff0
This special project was continued
in 1966 with explorations in the eastern portions of Areas SC and SB,
Washington.
The staff of three biologists and a fisheries
technician will be increased by the addition of two technicians with
funds made available under PL 88-309.

The four biologists engaged in flatfish project studies maintain a
constant surveillance of the fishery through market sampling and log

The sampling program affords meaning-

Market sampling emphasis is on Dover, English, and petrale
soles with animal food also receiving attention.
No tagging studies have been conducted since 1964, as
analyses and reporting of results of previous taggingwork and other
groundfish studies have priority.
English sole tagging off central

REVIEW OF JOINT PROJECTS
1.
glish Sole (PMFC Bulletin)
Leon Verhoeven, PMFC Executive Director, reported on
manuscript commitment and space assignments for Bulletin 7.
The major
part of this bulletin will be comprised of English sole papers contributed by member agencies of the Technical Sub-Committee.
2.
Petrale Sole
Discussion on petrale sole was culminated with the reaffirmation that a statement will be provided in 1967 on assessment of
fisheries with winter restrictions and on California's petrale fishery
which has no closures.

The increased use of synthetic materials and savings

The Shrimp Fishery
QJ O u l
Since the ocean shrimp fishery is apparently not within the present
terms of reference of the Joint Trawl Committee no exhaustive digest of
the regulations is herein presented.
It may be noted that California
sets over-all quotas on an area basis and has a winter closed season.
Oregon has a season but has no restrictions on the quantity of shrimp to
be taken and permits use of shrimp trawis" as well as beam trawls.
Washington has seasonal closures in certain inside waters of Puget Sound,
but permits year-round fishing with any suitable gear in coastal waters
and waters of the Pacific Ocean.
Washington regulations stipulate a
maximum distance between otterdoors and wings of shrimp trawl nets and
requires that undersized shrimp (described as unmarketable) must be
returned to the water with a 10% tolerance.
Canada apparently imposes
no restrictions on an ocean shrimp fishery.
However, the regulations
governing the retention of a fin-fish caught incidental to a lawful shrimp
fishery may be relevant to any study of the status of bottom fish stocks.
The existing provisions are cited below:
