The use of stable isotopes and stomach contents to idenrifi dietary components of the spotted rose snapper, Lutjanus guttatus (Steindachner, 1869), off the eastern coast of the southern Gulf of California

Abstract

The food habits of 81 organisms of the raucous grunt Haemulopsis leuciscus were analysed. The organisms were captured in Bahía Almejas, Baja California Sur, Mexico, during five bimonthly samplings (March–November 1998). The index of relative importance indicated that H. leuciscus consumed a total of eight prey-items, and the dominant prey were the gastropod Oliva spp., Conus spp., and scaphopod Dentalium spp.
