Fishery dependent data--length distributions, sex ratios, maturity schedules, and
species composition of landed catches--are necessary for stock assessments.
These data are currently collected by state port biologists using a sampling design
that randomly selects samples from a small percentage of a very large target
population. Sampling programs may need to increase the sample size and
possibly expand data collection times into evenings and weekends. This must
also be accomplished in an economically reasonable manner, which is a
significant challenge. Working cooperatively with the seafood processing plants is
one way to meet these challenges.
This study explored the feasibility of implementing a cooperative sampling program
for Pacific West Coast groundfish, with the goal of improving the precision and
accuracy of estimates derived from the fishery dependent samples. The study
was a cooperative project utilizing seafood processing plant workers to collect fish
length frequency data. There is evidence that the seafood plant workers can
measure fish with reasonable accuracy. This cooperative effort has the potential
to dramatically increase the sample size and the coverage of sampled catch
landings. / Graduation date: 2001
