Abstract

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.
