ABSTRACT

This award
completed involvement of the Gulf and South Atlantic Fisheries
Development Foundation, Inc. in a multi-organizational
multi-year research program to address bycatch in the
shrimp fishery of the southeastern U.S. Primarily,
this award supported continued at-sea data collection
by observers and Foundation efforts to disseminate information
about bycatch and its reduction to interested and affected
parties. During this award, observers logged 589
sea-days on 36 sampling trips in southeast U.S. waters
aboard 10 different participating commercial shrimp trawlers.
The catch in 671 paired tows was evaluated for the exclusion
capability of various experimental devices, or the exclusion
of various TEDs; additionally a minimal 3 tows were sampled
characterizing the catch of the South Atlantic rock shrimp
fishery. This effort contributed to a 1993-1996 Foundation-generated
database of 3,166 tows (55% of the programmatic database).
Since the Bycatch Program began, a wide variety
of types and configurations of bycatch-reduction devices
(BRDs) have been tested by this organization, and others.
Previous research has documented that two general
categories of BRDs (fisheyes and expanded mesh) can be
used to excluded substantial numbers and weight of finfish
without concurrent substantial shrimp loss.
