Diferença entre dois métodos de coleta utilizados na captura de crustáceos decápodes em um rio da Estação Ecológica Juréia-Itatins, São Paulo

Abstract: ABSTRACT. Differences between two methods used for sampling decapod crustaceans in a stream at Juréia-Itatins Ecological Station, state of São Paulo, Brazil. Sampling collections were taken quarterly from Fall 2000 to Summer 2001 at Juréia-Itatins Ecological Station using two different sampling methods (hand sieve and traps). Comparing both sampling methods one can verify differences in faunal composition, richness, degree of dominance, evenness and size and number of individuals. Moreover, the sex ratio of Ma… Show more

“…Animals often search for habitats that can fulfill their biological needs (e.g. feeding, reproduction, and avoidance of predators) (Müller et al, 1999;Rocha, 2010). In freshwater environments there is a stratification of the fauna directly related to the environmental conditions and shelter availability (Thomazi et al, 2008;Giuliatti & Carvalho, 2009).…”

“…Contudo, cada um deles mostrou-se eficiente na atração de grupos específicos de organismos. Assim, a eficiência de captura de cada armadilha dependerá principalmente do tipo de atrativo utilizado, o qual deverá corresponder às características alimentares das espécies-alvo, de modo que uma maior variabilidade de iscas provavelmente ampliaria o número de espécies capturadas (Sanches & Sebastiani, 2009;Rocha, 2010).…”

“…This single collected specimen of M. carcinus is probably due to the difficulty in collecting this species in gill and dip nets, because cove traps are generally used for this shrimp (Rocha 2010). The number of freshwater shrimp species in the state of Maranhão is now increased from 4 to 6 species.…”
