The purpose of this study was to infer the possible impact of unmonitored discard of by-catch on a recreational fishery. We recorded by-catch of fishes at a recreational fishery in Northeast Texas, statistically analyzed them, and then projected estimates of mortality if our observations represent a general pattern of behavior. Anglers discarded nine species of fishes during our study. The most frequently discarded fish were Gizzard Shad and Freshwater Drum. Four species of game fish were among the discarded species, but only Channel Catfish and Hybrid Striped Bass composed a large portion of the discarded fishes. Based on our observations, recreational fishing can produce a large amount of by-catch throughout the year and potentially pose an important unmonitored source of fish mortality.
This is an interesting paper. You might want to take a look at Balon EK (2000) Defending fishes against recreational fishing: an old problem to be solved in the new millenium. Environ Biol Fishes 57:1–8. and Dionys de Leeuw (1996). Contemplating the interests of fish: The angler’s challenge. Env. Ethics 18:373-390. Classic papers that tackle some of the ethical issues around angling which might link quite well with the take home message that anglers need to treat their prey with respect and minimise needless waste.
