Mortality of Spotted Seatrout, Red Drum, and Black Drum Caught in Gill Nets

In-net mortality of spotted seatrout (Cynoscion nebulosus), red drum (Sciaenops ocellatus), and black drum (Pogonias cromis) caught in gill nets with 7.6,10.2, 12.7, and 15.2 cm stretch mesh was determined in Texas bays during 1985-87. Spotted seatrout had greatest mortality (74%) followed by red drum (55%) and black drum (28%). For each species, in-net mortality was significantly different among meshes, among bays and between seasons. Among these 3 factors, mesh size was the most important in predicting mortality variation. In-net mortality was generally inversely related to mesh size,...

Comparison of Bait Types Used by Saltwater Sport-boat Anglers in Texas

Using results from on-site creel interviews, the use and fishing success of 16 bait types for 8 game fishes were studied for bay and pass saltwater sport-boat anglers in Texas. The success of catching at least 1 fish was evaluated using percentage of successful fishing parties by fish species, bay system, and bait type. For all fish species, the use of different baits was not proportional to the success of these baits in catching fish; however, we could not determine whether this was caused by ineffectiveness of the investigated bait or anglers not directing this bait toward the...
