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,...

Simulation of a Commercial Saltwater Trotline Fishery

The commercial trotline fishery in the Laguna Madre, Texas, was simulated using fishery-independent sampling data to estimate landings of black drum (Pogonias cromis). Simulation of a commercial fishery can provide landings estimates and more precise estimates of confidence intervals. It can also provide information (i.e., by catch) not available through self-reported systems.

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...
