Abstract

Trained National Marine Fisheries Service observers collected information on catch rates of shrimp and finfish aboard commercial shrimp vessels. Data from March 1988 through July 1989 comparing TED-equipped nets (Georgia TEDs with and without accelerator funnels) and standard shrimp nets were reported in May 1990 (Phase I). Data from September 1989 through August 1990 comparing TED-equipped nets (Super Shooter TEDs and Georgia TEDs, both with accelerator funnels) and standard shrimp nets are presented in this report (Phase 2). Specific objectives of the TED evaluation program were to: 1) Compare catch rates of shrimp from TED-equipped trawls and from standard trawls without TEDs in representative shrimp fishing areas of the Gulf and Atlantic coasts of the U.S. by season, 2) Provide data, results and analytical methods utilized in the study to the NMFS Economics Analysis Branch for use in an economic evaluation of impacts of TEDs.
