“…The latter, is common within scianids (MUNIZ & CHAVES 2008) and results in large numbers of individuals becoming vulnerable to the trawls at once. This observation may be corroborated by the observed noted pulse spawning period in the south between October and December for main species of the Stellifer genus (CHAVES & VENDEL 1997, ALMEIDA & BRANCO 2002 and during spring and summer for P. brasiliensis , ROBERT et al 2007.…”

The present study analyzed qualitatively and quantitatively the temporal and spatial changes in the fish assemblages present in seabob shrimp distribution sites in two important fishing areas of the Santa Catarina coast. Monthly bottom trawls, conducted between March 2007 and February 2008 in Balneário Barra do Sul and Penha, yielded a total of 38,608 specimens belonging to 54 species, of which 35 occurred in both regions. The Sciaenidae was the most represented family in both number of species and abundance of individuals. The dominant species were Stellifer rastrifer (Jordan, 1889), S. brasiliensis (Schultz, 1945), Paralonchurus brasiliensis (Steindachner, 1875), Isopisthus parvipinnis (Cuvier, 1830), Trichiurus lepturus (Linnaeus, 1758), and Pellona harroweri (Fowler, 1917). The ichthyofaunal structure showed a spatiotemporal dependence with significant differences in March 2007 and January and February 2008 between Balneário Barra do Sul and Penha. The main differences were attributed to dominant species, which were responsible for significantly altering the abundance of the assemblages. The species richness was similar in both sites, whereas the diversity and equitability indices showed monthly fluctuation patterns that differed between Balneário Barra do Sul and Penha. The Shannon index differed in August, September and November 2007 and January and February 2008, with an H' ranging from 0.74 to 1.98 influenced by dominant species, whereas significant variations were observed for the Pielou index in November 2007 and February 2008. The Berger-Parker index demonstrated a clear dominance pattern where the monthly numeric contribution of a single species ranged from approximately 30 to 80%. Although the results showed differences between fishing grounds 25% of the time, we conclude that fish assemblies captured as accompanying fauna in artisanal seabob shrimp fisheries showed statistically similar characteristics for most of the year, although Balneário Barra do Sul and Penha are 35 km away from each other

“…However, in the present study, peaks of mean size did not occur only during dry periods, such as autumn 2004, but also in late spring 2003 and midspring 2004. These peaks concord with reproductive peaks previously reported for these species (ALMEIDA; BRANCO, 2002;SOUZA;CHAVES, 2007). Therefore, abrupt increases in mean length may also represent the entry of mature individuals during reproductive periods, in order to reach ideal spawning areas (nearer the estuary mouth).…”

“…Evaluations of weight-length relationships and condition factors are available for three species (COELHO et al, 1985(COELHO et al, , 1987BRAGA, 1986;PAIVA-FILHO, 1990b, 1995VENDEL, 1997;MOURA, 1998;FIGUEIREDO-FONSECA;LOBÃO DE SOUZA, 2006;BRANCO, 2002;FREIRE et al, 2009), although some discrepancies among species values may lead to misinterpretation. The present study is the first to evaluate the relative condition factor (LE CREN, 1951), based on weight-length relationships.…”

Population biology of Stellifer rastrifer, S. brasiliensis and S. stellifer in Caraguatatuba Bay, northern coast of São Paulo, Brazil

Ecosystems may reflect environmental changes in many respects, from the debilitation of individuals to alterations in community composition. Equally, population parameters may provide reliable indications of environmental changes. Members of the sciaenid fish genus Stellifer are usually very abundant where they occur, often with two or more species living in sympatry. Here, the population dynamics of three Stellifer species from southeastern Brazil were assessed. Sampling was carried out in shallow marine areas of Caraguatatuba Bay, from August 2003 to October 2004. The species evaluated were Stellifer rastrifer (n=3183), S. brasiliensis (n=357) and S. stellifer (n=116). The area under greater continental influence tended to support more, but smaller individuals. Size variations over time were similar among species and negatively correlated with Krel, which showed smooth fluctuations. The general length-frequency distribution was concentrated between 6.0 and 9.0 cm, and the great majority of females did not present mature gonads during the sampling period. The findings support the existence of a stratification by size for these species, indicating that the area is essential for the development of younger fish. Failure to consider these characteristics for the management of similar areas may have serious implications for these environments.
Os ecossistemas podem refletir mudanças ambientais em muitos aspectos, desde o enfraquecimento dos indivíduos até alterações na composição da comunidade. Do mesmo modo, os parâmetros populacionais podem fornecer indicações confiáveis de mudanças ambientais. Sciaenídeos do gênero Stellifer são peixes geralmente muito abundantes e em suas populações é frequente a ocorrência de duas ou mais espécies simpátricas. No presente trabalho, a dinâmica populacional de três espécies de Stellifer do sudeste do Brasil foi avaliada. A amostragem ocorreu em águas rasas das zonas marinhas da Baía de Caraguatatuba, de agosto de 2003 a outubro de 2004. As espécies avaliadas foram Stellifer rastrifer (n = 3.183), S. brasiliensis (n = 357) e S. stellifer (n = 116). Os resultados mostraram que a área sob maior influência continental tende a suportar um número maior de indivíduos menores. Variações de tamanho ao longo do tempo foram semelhantes entre as espécies e negativamente correlacionadas com o Krel, que apresentou flutuações suaves. De modo geral a distribuição de freqüência de comprimento ficou concentrada entre 6,0 e 9,0 cm e para a grande maioria das fêmeas as gônadas se apresentaram imaturas durante o período avaliado. Os resultados suportam a existência de estratificação populacional por tamanho dentro destas espécies, indicando que a área é apropriada para o desenvolvimento de juvenis. A desconsideração de tais características pode acarretar sérias implicações para a gestão dessas áreas

“…A similar length distribution for the congener species Stellifer stellifer was found by Almeida and Branco (2002), in Penha, a county in Santa Catarina Satate, located only a few miles from Porto Belo, when in the fall of 1997 64.5% of the sample were represented by individuals shorter than 8 cm. A larger number of sampled juveniles was also found by Rodrigues-Filho et al (2011) in the same area.…”

Feeding habits of the congeneric species Stellifer rastrifer and Stellifer brasiliensis (Acanthopterygii: Sciaenidae) co-occurring in the coast of the state of Santa Catarina, Brazil

The objective of the present study was to investigate the feeding habits allowing the occurrence of the congeneric species Stellifer rastrifer and Stellifer brasiensis, collected on a seasonal basis, in the operating area of the artisanal seabob-shrimp trawl fishery in Porto Belo, an important fishing area on the southern Brazilian coast. Fish were collected seasonally from November 2009 to August 2010, in isobaths of 10, 20 and 30m. Of the 450 stomachs analyzed, 194 belongd to Stellifer rastrifer and 242 to Stellifer brasiliensis. From the totality of analyzed stomachs 33.49% were empty and 66.52% had some content. Crustacea were the predominant food category in the diet of S. rastrifer and S. brasiliensis, and the shrimp Acetes americanus was the most frequent crustacean in stomachs of both studied species. The overlapping in the diet of the species was high, however when analyzing the overlap in each season it was found that it occurred only during spring and winter. Although the most important items in the diet of these species are the same, the intake of each alternates in time, suggesting a difference in predation pressure, which leads to less direct competition in a given time.Keywords: competition, fish diet, feeding overlap, shrimp fisheries, Stellifer. A sobreposição na dieta foi alta, porém a cada estação do ano, verificou-se que a sobreposição ocorreu apenas durante a primavera e o inverno. Embora os itens mais importantes na dieta destas espécies sejam os mesmos, o consumo de cada um é alternado no tempo, o que sugere uma diferença na pressão de predação, levando a uma menor competição direta em um determinado momento.
