Biologia populacional de Callinectes ornatus associada í­Â  pesca do camarão-sete-barbas, rio São Francisco (Alagoas e Sergipe, Brasil)

Abstract: RESUMO Este trabalho investigou a maturidade sexual, o período reprodutivo e de recrutamento (ambos relacionados com a temperatura e a salinidade da água), e a proporção sexual de Xiphopenaeus kroyeri na Baía de Santos, SP. Os camarões foram capturados mensalmente, de junho de 2008 a maio de 2009, em quatro pontos de amostragem. Os indivíduos foram mensurados, analisados quanto ao sexo e o estágio de desenvolvimento reprodutivo foi determinado macroscopicamente. As fêmeas apresentaram valor médio de compriment… Show more

“…As seen in other decapods, the distribution patterns and abundance variation of A. cribarius may be modulated by many environmental factors, which can determine the occupation or restriction of a species to a certain area (MANTELATTO et al, 1995;MANTELATTO and FRANSOZO, 1999a). Crabs in general have a very conspicuous bathymetric distribution pattern (BERTINI and FRANSOZO, 2004;SANTOS et al, 2016), possibly associated with the distribution of biotic (e.g., organic matter in sediments) and abiotic factors (e.g., types of sediment, temperature and salinity) (PINHEIRO et al, 1997). GUILLORY et al (2001) defend the idea that crabs select their habitat based on the particular physiological needs of each stage of their life cycle, given that they may inhabit the planktonic, nektonic or benthic strata depending on their current stage.…”

“…In the fluvial zone, turbidity may have acted directly reducing the success of prey capture, since most species of this guild rely on sight to capture food (Guthrie, 1986; Ranaker et al, 2012; Rodrigues et al, 2020). In the lacustrine zone, however, greater flow may have resulted in a process of water fertilisation, which in turn may have increased prey availability for piscivores, apparently in a bottom‐up process (Medeiros et al, 2014; Pinto et al, 2011; Thomas et al, 2007).…”

“…These guilds exhibited an opposite relationship of their abundance with higher turbidity values in the fluvial zone. The species that compose these guilds are characterised by high consumption of allochthonous resources, such as terrestrial insects and seeds, using the new flooded environments as foraging and refuge sites (Pinto et al, 2011; Quirino et al, 2018). In this case, greater dispersion to newly flooded areas, together with unfavourable conditions of high turbidity and water turbulence, may have led to a decrease in fish abundance in the original river bed.…”

“…Endêmica do Brasil: Não Litopenaeus schmitti é uma espécie nerítica e pode ser encontrada no oceano Atlântico ocidental, desde a Baia de Matanzas em Cuba até o Uruguai (Costa et al, 2003;Santos, Severino-Rodrigues & Vaz-dos-Santos, 2008;Spivak et al, 2019).…”
