Commercial fisherman contend that large mesh gill nets can be used to catch black drum (Pogonias cromis), sheepshead (Archosargus probatocephalus), and southern flounder (Paralichthys lethostigma) without catching red drum (Sciaenops ocellatus) and spotted seatrout (Cynoscion nebulosus). The Texas Parks and Wildlife Department examined this contention in the Corpus Christi Bay and Laguna Madre systems during September - December 1981 with gill nets of 15.2-17.8 cm (6-7 inch) stretch mesh constructed of either monofilament or multifilament webbing. The results of this study, in addition to previous studies, indicate that gill nets cannot be used in Texas bays to select for some species of fish and simultaneously exclude red drum and spotted seatrout.
