“…The larger individuals may also feed on other fish (SINQUE, 1977;PUIG, 1986;VAZZOLER, 1991;MENDOZA-CARRANZA & VIEIRA, 2008). These studies also report that polychaetes and crustaceans predominate in the diet of this species (TANJI, 1974;VAZZOLER, 1975;AMARAL & MIGOTTO, 1980;GASALLA, 1995;FIGUEIREDO & VIEIRA, 1998;FRERET & ANDREATA, 2008;MENDOZA-CARRANZA & VIEIRA 2008). M. furnieri feeds continuously and does not have a determined feeding period (SOARES et al, 1993;FIGUEIREDO & VIEIRA, 1998).…”

Feeding habits of whitemouth croaker Micropogonias furnieri (Perciformes: Sciaenidae) in Caraguatatuba Bay, southeastern Brazil

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.

“…Vários autores verificaram que, apesar de P. brasiliensis apresentar o item Crustacea em sua dieta, sua alimentação é preferencialmente anelidófaga (Amaral & Migotto 1980, Braga et al 1985, Capitoli et al 1994, Micheletti & Uieda 1996, Jucá-Chagas 1997, Soares & Vazzoler 2001. Apesar da alta preferên-cia por Polychaeta, as correlações entre P. brasiliensis e L. schmitti foram significativas, estando as duas espécies representadas no segundo eixo da CCA e com influência dos transectos rasos (5, 15 e 25 m), locais onde também foram observados sedimentos mais finos.…”

Abstract:To study the relationships among Sciaenidae fish and Penaeoidea shrimp biomass, fieldwork was carried out in the north coast of São Paulo state, Brazil, during the four seasons of 2001. Samples were collected in transects from different depths at Ubatuba, Caraguatatuba, and São Sebastião cities. Water and sediment were collected from each transect. The hypotheses that the environmental factors were different among the seasons and depths were tested by ANOVAs. The statistical dependence among the biomasses of fishes (response variable) and the biomasses of shrimps (covariable) in the three sections was tested by an ANCOVA model. CCA was used to quantify the relationships among each species' biomass. The seasons and sections important at the CCA results were evaluated by Kruskal-Wallis test and depth by Spearman's test. The temperatures and salinities were significantly different among seasons but organic matter and phi were not. A total of 378,618 g of fish and 79,338 g of shrimp were collected and the majority was captured during the winter and in shallow transects. The greatest biomass of both groups was captured at Caraguatatuba and the correlation between fish and shrimp captures was negative. A positive correlation was found in the other areas. Therefore, data from Caraguatatuba was removed from the final ANCOVA model, in which 47% of Sciaenidae biomass variability was explained by the presence of Penaeoidea shrimps. Xiphopenaeus kroyeri was the only important factor in Sciaenidae distribution in the axis 1, while axis 2 indirectly evidenced the depth gradient. The results suggest that many fish species search for the same areas where shrimp occurs, related to abiotic factors, and use them as food resource. Resumo: Visando analisar as associações entre as biomassas de peixes Sciaenidae e de camarões Penaeoidea, foram feitas amostragens com barco de arrasto nas quatro estações do ano de 2001, em um gradiente de profundidade, nas regiões de Ubatuba, Caraguatatuba e São Sebastião. Em cada transecto, foram obtidas amostras de água e de sedimento. As hipóteses de que os fatores ambientais foram diferentes entre as estações do ano e profundidades foram testadas por ANOVAs. A dependência estatística entre as biomassas de peixes (variável resposta) e as biomassas de camarões (covariável) nas três regiões, foi testada por um modelo de ANCOVA. Para quantificar as relações entre as biomassas de cada espécie foi utilizada a CCA. A importância das estações do ano e das regiões no resultado da CCA foi avaliada pelo teste de Kruskal-Wallis e da profundidade pelo teste de Spearman. Nas estações do ano, as temperaturas e salinidades foram significativamente diferentes, o que não ocorreu com matéria orgânica (MO) e o diâmetro médio do sedimento (phi = Ф). Foram amostrados 378.618 g de peixes e 79.338 g de camarões, com maiores capturas no inverno e nas menores profundidades. Em Caraguatatuba foram coletadas as maiores biomassas de ambos os grupos e a correlação entre as capturas de peixes e de camarões foi negativa. ...
