Description:A literature review of bycatch in the US Gulf of Mexico menhaden fishery, the second largest commercial fishery in the continental US by weight, was conducted to determine the potential bycatch of red drum (Sciaenops ocellatus) in the fishery. Information regarding bycatch is patchy and sparse, both temporally and spatially, with the majority of studies suggesting a negligible amount of bycatch. In this paper, we review the available literature addressing species composition and magnitude of bycatch in the Gulf menhaden fishery and use this information to generate bycatch estimates for red drum using simplistic assumptions and minimal data. This analysis emphasizes the difficulty in trying to identify whether bycatch is a substantial issue for red drum and how to quantify appropriate estimates in the absence of data. At the very least, this analysis should highlight the possibility of bycatch in the menhaden fishery and the importance of investigating the potential impact on stock dynamics. In this working paper, we briefly review the various studies addressing bycatch in the Gulf menhaden fishery and summarize findings concerning red drum or similar species (i.e., other drums). The purpose of this study to highlight the need to consider the potential impact of bycatch in the Gulf menhaden fishery for economically important species such as red drum, or other species such as Spanish mackerel (Scomberomorus maculatus) (Harrington et al. 2005). We provide a preliminary estimate of red drum bycatch in the Gulf of Mexico menhaden fishery based on simplistic assumptions and minimal data. At the very least, this analysis should highlight the need to address the potential for bycatch in the menhaden fishery.
