摘要

本研究提供了墨西哥加利福尼亚湾东岸底栖区虾副渔获物中最丰富和最常见的一种蜥蜴鱼(Synodus scituliceps)的食性信息。对2004年8月至2005年3月捕获的114种生物进行胃内容物分析，采用莱文指数。最重要的猎物种类是底栖鱼类:阔尾鳞鱼(Eucinostomus currani)、自由鳞鱼(Opisthonema libertate)、露头鳞鱼(Synodus lucioceps)和加州副鱼(parichthys californicus)。根据莱文指数(bi = 0.39)， S. scituliceps是一种专门捕食软底鱼的鱼食性捕食者，幼鱼和成年鱼的饮食相似。

Dieta del pez chile lucio Synodus scituliceps (Aulopiformes: Synodontidae) en la Costa Este del Golfo de California, México

This study provides information on feeding habits of the lizardfish Synodus scituliceps , one of the most abundant and frequent species in shrimp by-catch in the demersal area in the eastern coast of the Gulf of California, Mexico. Stomach content analyses were performed on 114 organisms caught from August 2004 to March 2005, and Levin's index was applied. The most important prey species were benthic fishes: Eucinostomus currani, Opisthonema libertate, Synodus lucioceps and Paralichthys californicus. According to the Levin’s index ( B i = 0.39), S. scituliceps is a piscivorous specialist predator in soft bottoms, with similar diet in juveniles and adults.
