Captura, esfuerzo y captura incidental de la pesca con espinel en el centro de Perú

Abstract

El objetivo del presente trabajo es dar a conocer algunas características de los viajes de pesca, esfuerzo, captura, peces objetivos, áreas de pesca y captura incidental obtenida a partir de observadores a bordo y bitácoras de pesca. El 85% de los lances se produjeron en los primeros 574 Km de distancia a la costa (309 millas náuticas). El lance más distante estuvo a 1320 Km (712 millas náuticas). Se lanzaron 382000 anzuelos para perico, en 224 lances y 29 viajes de pesca, 94.6% de la captura en peso fue de perico, 2.7% de tiburón azul (Prionace glauca) y 1.3% de diamante (Isurus oxyrinchus). Además, 103790 anzuelos capturaron tiburón, en 109 lances y 12 viajes de pesca, 81,9% de la captura en peso fue de tiburón azul y 16.8% de diamante. La Captura por Unidad de Esfuerzo (CPUE) para perico mostró diferencias significativas entre estaciones, con un máximo entre noviembre y enero. En lo que refiere a tiburón, la CPUE por estaciones también mostró diferencias significativas, los meses con mayores capturas fueron setiembre y octubre. La tortuga verde, Chelonia mydas agassizii, fue la más capturada y dos de cada tres fueron juveniles. Todas las tortugas cabezonas, Caretta caretta, fueron juveniles. Se reporta la captura de un petrel y al parecer, la captura de mamíferos sería escasa. Considerando el gran esfuerzo de esta pesquería, existe la necesidad de monitorearla para contar con información que permita establecer las correspondientes medidas de manejo.
