AbstractPopulations of Red Snapper Lutjanus campechanus in the Gulf of Mexico remain overfished, but overfishing has been ended. Historically, rebuilding plans were based almost entirely on the reduction of shrimp trawl bycatch mortality, which was believed to account for 80% of the total juvenile Red Snapper mortality. This estimate was based on the assumption that juvenile Red Snapper had low rates of natural mortality. Bycatch reduction devices were believed to be capable of reducing bycatch mortality by more than 50%, which would enable the stock to rebuild without any other management actions. Over the years, new information has shown that natural mortality rates of juvenile Red Snapper are four times higher than originally estimated, and bycatch mortality is presently estimated to comprise only about 4% of the total juvenile mortality. Hence, bycatch reduction, regardless of the means by which it is achieved, will not be very effective for rebuilding the Red Snapper stock. Limits on the harvest of a...
