  • Description:
    As long as fishermen specialize their efforts in trying to harvest only a few select species, there will almost always be the problem of unwanted fish in a catch. Such is the case in the shrimp fishery, where the amount of fish caught incidental to trawling often exceeds by three or four times the amount of shrimp caught. In the past, and today, these fish are simply thrown back into the sea. However, because of growing national and international demands for protein and a slow expansion of current protein sources, the prospect of utilizing the incidental fish caught during trawling operations is being investigated. This study evaluates the nature of the markets potentially available for trawl fish and estimates potential volumes which could be marketed through these channels. Identification of potential markets was accomplished by determining the magnitude and composition of trawl fish. Through interviews and a review of biological studies it was found that most trawl fish were less than one pound live weight and the majority of them belonged to the sciaenid family (black drum, croaker, and seatrouts); longspine porgy was the most numerous species. As yet there is no precise estimate on the amount of fish discarded in the Western Gulf of Mexico, but it lies somewhere between 52 and 368 million pounds
