As a result, fish of a given species are absent from their geographic range and EFH for much of the year, ... individuals behave and select habitats in ways that maximize their fitness in the manner in which natural selection iteratively operated on their ancestors. WebIn 2011, an intensive, multiple-gear, fishery-independent survey was carried out in the northern Gulf of Mexico (GOM) to collect comprehensive age and length information on Red Snapper Lutjanus campechanus. Based on this synoptic survey, we produced a spatial map of Red Snapper relative abundance that integrates both gear selectivity effects and …
