Twenty-seven comparison tows were made between a 2-seam otter trawl with 6 loops of 13 link, 4.8-mm chain attached to the leadline (original net) and an identical trawl with additional chain loops attached every 25.4 cm across the entire leadline (heavily chained net) during June-August 1988 in tributaries of the Neuse River, N.C. Objectives were to determine the effect of the heavily chained net on the juvenile finfish, crab, and shrimp catch-per-unit-effort (CPUE) estimates and the feasibility of developing conversion factors to convert CPUE estimates from one net type to the other.

Fourteen radio-tagged adult hybrid striped bass (female Morone saxatilis x male M. chrysops) were tracked from February to November 1987 in Ross Barnett Reservoir, Mississippi. Radio-tagged hybrids moved into the Pearl River in early March and remained upstream until water temperatures exceeded 27° C and dissolved oxygen decreased below 4 mg/liter at which time all except 2 fish returned to the main lake. These 2 fish, remaining in a well-aerated refuge at a lowhead dam, died in July when water temperatures exceeded 30° C. The fish which returned to the main lake showed decreased movements...
