Estudo sobre a ictiofauna acompanhante da pesca do camarão sete-barbas (Xyphopenaeus kroyeri) nas proximidades da Baía de Santos - SP: I - aspectos quantitativos

Spatiotemporal variations of the ichthyofaunal structure accompanying the seabob shrimp, Xiphopenaeus kroyeri (Crustacea: Penaeidae), fishery in important fishery areas of the Santa Catarina shore, Brazil

“…However, the consistently low selectivity of this bottom trawl gear does not result in similar composition and abundance of the fish that are caught in different fishing areas, and disparities in the number of species present in shrimp fisheries are frequent in the literature (COELHO et al 1986, PAIVA-FILHO & SCHMIEGELOW 1986, RUFFINO & CASTELLO 1992, CHAVES et al 2003, GOMES & CHAVES 2006, SANTOS et al 2008.…”

“…The fishes in this family are commonly found in shallow continental shelf over sand or mud substrates (MENEZES & FIGUEIREDO 1980), and most are demersal and dominate the accompanying fauna in artisanal seabob shrimp fisheries (COELHO et al 1986, PAIVA-FILHO & SCHMIEGELOW 1986, GIANNINI & PAIVA-FILHO 1990, RUFFINO & CASTELLO 1992, SANTOS et al 1998, HOSTIM-SILVA et al 2002, CHAVES et al 2003, VIANNA & ALMEIDA 2005, BRANCO & VERANI 2006a, b, GOMES & CHAVES 2006, SCHWARZ JR et al 2007, SOUZA et al 2008. In southeastern and southern regions, the most abundant species captured as accompanying fauna are P. brasiliensis, C. gracilicirrhus, Micropogonias furnieri (Desmarest, 1823), M. americanus, L. breviceps, S. brasiliensis, S. rastrifer, Cynoscion jamaicensis (Vaillant & Bocourt, 1883 and I. parvipinnis (COELHO et al 1986, PAIVA-FILHO & SCHMIEGELOW 1986, MUTO et al 2000, BRANCO & VERANI 2006a, b, SCHWARZ JR et al 2007, SOUZA et al 2008. Therefore, as observed along the Brazilian coast, this family, represented by 13 species and accounting for over 60% of the total abundance, was predominant in terms of number of species and abundance in the Balneário Barra do Sul and Penha regions.…”

“…In a study by TISCHER & SANTOS (2001), the ichthyofauna accompanying a shrimp fishery in the mouth of the São Francisco River (northeastern Brazil) showed an average diversity of 3.20. On the São Paulo coast (southeastern Brazil), PAIVA-FILHO & SCHMIEGELOW (1986) recorded values between 1.64 and 3.07 for Santos Bay, whereas, in São ZOOLOGIA 28 (2): 151-164, April, 2011 Sebastião, MUTO et al (2000) observed variation between 1.93 and 2.67. In the state of Santa Catarina (southern Brazil), the diversity ranged between 1.11 and 1.97 in seven years of sampling in the Penha region (BRANCO & VERANI 2006a) and between 1.98 and 2.50 in five years of sampling in the Itajai-Açú river estuary (BRANCO et al 2009).…”

“…In the last decades, the composition, diversity and spatiotemporal variations of ichthyofauna have been the focus of a number of studies along the Brazilian coast (COELHO et al 1986, PAIVA-FILHO & SCHMIEGELOW 1986, RUFFINO & CASTELLO 1992, SANTOS et al 1998, SANTOS 2000, TISCHER & SANTOS 2001, GRAÇA LOPES et al 2002, BRANCO & VERANI 2006a, b, GOMES & CHAVES 2006, SCHWARZ JR et al 2007), but only a few studies have compared among fishing grounds (CHAVES et al 2003, SOUZA et al 2008.…”

Análise quali-quantitativa da ictiofauna acompanhante na pesca do camarão sete-barbas, na Armação do Itapocoroy, Penha, Santa Catarina

“…Neste estudo, os valores médios dos índices de diversida-de e equitabilidade foram influenciados diretamente pelas flutuações sazonais das populações, variando em torno da amplitude esperada para a ictiofauna de regiões costeiras (ZANI-TEIXEIRA & PAIVA-FILHO 1981, PAIVA-FILHO & SCHMIEGELOW 1986, PAIVA-FILHO & TOSCANO 1987, YAÑEZ-ARANCIBIA et al 1988, PEREIRA 1994, onde poucas espécies numericamente dominantes, aparentemente são características comuns em associações de peixes demersais (ANSARI et al 1995).…”
