Growth parameters estimates of Maurolicus stehmanni Parin & Kobyliansky 1996 (Teleostei, Sternoptichydae) from south and southeastern Brazilian waters

Abstract: Este estudo, baseado na análise da microestrutura dos otólitos de Maurolicus stehmanni, apresenta estimativas dos parâmetros de crescimento e longevidade para esta espécie que habita a plataforma externa e o talude da ZEE sul-sudeste do Brasil. Estes parâmetros são importantes para o conhecimento da estratégia de vida da espécie e para o manejo deste recurso, que constitui um importante elo entre os componentes iniciais e finais da teia alimentar no ecossistema de mar aberto, sendo um dos principais itens na d… Show more

“…The estimated mean somatic growth rate for M. muelleri in the BoB (0.20 mm day⁻ 1 ) is comparable to that reported by [36], who studied the growth of M. muelleri larvae in a Norwegian fjord (0.20 mm day⁻ 1 ), and slightly lower than the estimate for juveniles in the CS area (0.26 mm day⁻ 1 ) [21]. Slower growth rates were also observed in other congeners: M. stehmanni in Brazilian waters (0.19 mm day⁻ 1 ) [37], M. australis larvae (0.16 mm day⁻ 1 ) in Chilean Patagonia [38], and M. mucronatus (0.15 mm day⁻ 1 ) in the Red Sea [39]. Excluding the growth rate reported for this species in the CS, this parameter slightly varied from 0.15 to 0.20 mm day −1 in habitats as diverse as the Red Sea or Brazilian waters.…”

“…The von Bertalanffy growth model (VBGM) (von Bertalanffy, 1938) was fitted to age data using Solver in Microsoft Excel (Kelly et al, 1997;Bellucco et al, 2004;David et al, 2005) for both observed and back-calculated lengths at age, for males and females separately and together, using the equation:…”

“…Os valores iniciais do comprimento máximo teórico (L ∞ ), da taxa de crescimento (k) e da idade teórica de comprimento zero (t o ) foram atribuídos com base na literatura. Foi necessário fixar o comprimento máximo teórico no valor máximo de comprimento observado (Bellucco et al, 2004), viabilizando o ajuste iterativo, em função da baixa representatividade amostral das idades maiores. Utilizouse o aplicativo Solver do Microsoft Excel para os ajustes (Kelly et al, 1997;Bellucco et al op.…”
