Rojo-Vázquez Enrique Godínez Domínguez Francisco Arreguín Sánchez Ciencias de la Tierra Mexico gillnet Jalisco selectivity fish power Gillnet selectivity, fishing power and catchefficiency for Microlepidotus brevipinnis (Steindachner,1869) off Bahia de Navidad, Jalisco, Mexico, were estimated.Field experiments were conducted using gillnets of 7.62 and8.89 cm of mesh-size, during April 1994 to March 1995. Atotal of 457 organisms were caught with the 7.62 cm meshsize,and 592 with the 8.89 mesh-size. Results shows gillnet of8.89 cm mesh size caught 3 cm larger organisms and 110 gmore weighted fish than those caught by the 7.62 mesh-size.The 7.62 mesh-size caught 1.9 times organisms and 1.3 moreweight than the 7.62 cm mesh-size. Selectivity analysisindicates an optimum length (100% probability of retention)was 27.7 cm TL for the 7.62 mesh-size and 32.3 cm TL for the8.89 cm mesh-size. The relative efficiency analysis wasestimated as relative catchability ratio between nets and itvaried in a range of 25% to 39% with fish length. 2001 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47936102 en http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.1 Vol.36 |
