Onboard Observing

In 2001, ADF&G shellfish biologists observed onboard several commercial beam trawl shrimp fishing vessels. The objectives of observing onboard beam trawl vessels were to:

  • gain a better understanding operating conditions and constraints of the beam trawl shrimp fishery;
  • investigate species composition of beam trawl catch and bycatch;
  • describe the size and species composition of unsorted raw beam trawl shrimp catch;
  • improve documentation of the distribution of commercial grounds for northern and sidestripe shrimp; and to
  • begin to formulate ideas about how best to assess this fishery.

The beam trawl onboard observer program was curtailed in 2004 due to insufficient Department resources and sharp declines in beam trawl effort in response to very poor market conditions.

Dockside sampling

Due to the current small fishing effort there is currently no dockside sampling program for the trawl shrimp fishery. However, in the past data collected during dockside sampling was used to generate catch size frequencies. This data was used in the management plan for the fishery, and is useful for evaluating year class cohorts.
