Abstract

Feeding ecology of Sillago sihama and Sillago ingenuua and interrelationship with other 15 fish species, including Stolephorus commersonii, Escualosa thoracata, Lutjanus russelli, Terapon puta, Ambassis kopsii, Ambassis vachellii, Dendrophysa russelli, Gerres filamentosus, Leiognathus decorus, Leiognathus splendens, Leiognathus equulus, Thryssa hamiltonii, Carangoides  praeustus, Lethrinus lentjan, and Pomadasys maculatum, utilizing coastal waters off the southern part of the South China Sea were investigated. Dietary contents from 4308 guts of those species collected during July 2003–May 2005 were examined. They were significantly grouped, based on similarity coefficient, into five feeding clusters (P < 0.01). Of these, most of the diets were dominated by calanoid copepods, shrimps, polychaetes and gammarid amphipods. Comparative study on two sillaginid species showed that both Sillago sihama and Sillago ingenuua were carnivores fed mainly on polychaetes and other benthic organisms. Dietary ontogenetic change of Sillago sihama was very distinctive where small sized classes started feeding mainly on calanoid copepods before changing almost completely to polychaetes. The two species applied both sharing and partitioning strategies for food, depending on size classes, to live with each other.
