Abstract
Reduction of the by-catch in shrimp fishery is an important goal worldwide. In order to compare by-catch using the conventional trawling net and a newly designed short funnel net, nine cruises were carried out by the commercial fleet operating in the Gulf of Tehuantepec, Mexico. A total of 480 trawls were done (mean duration: 85 min). The experimental trawls using the modified net produced a 21.13-28.86 % by-catch reduction (confidence interval 95 %), a 3 % increase of shrimp catch, and a significant reduction on net recovery time. Rev. Biol. Trop. 55 (3-4): 889-897. Epub 2007 December, 28.
La reducción de la fauna de acompañamiento del camarón (FAC) es uno de los temas de discusión más importantes en la pesca mundial. Con la finalidad de contribuir en este tópico, se diseñó y utilizó una red de arrastre variando la longitud del túnel, y se comparó su efecto con el de una red tradicional; durante 9 cruceros de la flota comercial en el Golfo de Tehuantepec, México. Se realizó un total de 480 lances con promedio de 85 min cada uno. Los arrastres de la red modificada mostraron mejores resultados, con variación entre 21.13 a 28.86 %, con un 95 % de confianza de reducción de FAC, un incremento de 3 % en la captura de camarón, y una disminución del tiempo de recuperación, lo que sugiere un incremento en la eficiencia gracias al nuevo diseño.
