DENADAI, Márcia Regina et al. Feeding habits of whitemouth croaker Micropogonias furnieri (Perciformes: Sciaenidae) in Caraguatatuba Bay, southeastern Brazil. Braz. j. oceanogr. [online]. 2015, vol.63, n.2, pp.125-134. ISSN 1679-8759.  http://dx.doi.org/10.1590/S1679-87592015084706302.

This study examined the feeding habits of Micropogonias furnieri in Caraguatatuba Bay. Samples were collected monthly between May 2003 and October 2004 by trawling in two areas (southern and northern parts of the bay). The fish were measured and their stomach contents identified. The abundance was compared between areas and among months. M. furnieri was more abundant in the southern area and in the spring of 2003. The population was dominated by small immature individuals. This species had a varied diet, feeding on crustaceans, bivalve siphons, and polychaetes. The ingestion of bivalve siphons may be an opportunistic behavior, due to the presence of a large bank of the bivalve Tivela mactroides in the study area. The high proportion of unidentified organic matter in the stomach corroborates published reports that this species eats continuously and has rapid digestion. These results demonstrate that M. furnieri can be considered a carnivore, with a preference for benthic organisms.
