Relação peso-comprimento e fator de condição de Oligosarcus hepsetus (Cuvier, 1829) no Parque Estadual da Serra do Mar - Núcleo Santa Virgínia, Mata Atlântica, estado de São Paulo, Brasil

Abstract: Abstract:In this work the length-weight relationship and the condition factor of Oligosarcus hepsetus were analyzed in the Grande river within the Santa Virgínia Unit of the Serra do Mar State Park, State of São Paulo. The length-weight relationship was esteemed for immature, females and male, through the expression W = aL b .The parameters a and b were dear after logarithmic transformation of the data of weight and length and subsequent adjustment of a straight line to the points for the method of the minimum… Show more

“…The survival of the species in different areas depends on the environmental adaptability, which exerts an influence on feeding and reproductive events throughout the life cycle of the species (Gomiero et al 2010) in such a way that changes in the condition factor may be related to the characteristics of each environment (Le Cren 1951). The mass-length relationship and relative condition factor of introduced species vary with the time of introduction, population size, environmental characteristics, intra-and interspecific interactions, and sexual maturity (Gomiero et al 2008).…”

“…In this regard, the mass-length relationship is a quick and easy way used to describe the growth without considering the fish age (Gomiero et al 2010). The determination of the mass-length relationship in fish can describe the structural characteristics of individuals within the population (Benedito-Cecílio and Agostinho 1997).…”

“…GOMIERO et al (2010) relatam que a higidez nos peixes reflete as condições nutricionais e de reservas, paralelamente às condições ótimas ambientais e aos aspectos comportamentais das espécies. Estes aspectos são similares ao contínuo investimento energético observado em E. brasilianus, que apresenta desova múltipla (SILVA et al, 2005).…”

“…O FC é um importante indicador do grau de higidez dos animais e seu valor reflete as condições nutricionais recentes e gastos das reservas em atividades cíclicas (GOMIERO et al 2010). Assim, a ausência de diferença entre os tratamentos testados evidencia que as diferentes fontes lipídicas não influenciaram o estado fisiológico dos juvenis de piava utilizados no estudo.…”
