Reprodução do bagre amarelo, Cathorops spixii (Agassiz) (Siluriformes, Ariidae), da Baía de Pinheiros, região estuarina do litoral do Paraná, Brasil

Abstract: O presente estudo investigou a biologia reprodutiva do bagre amarelo Cathorops spixii (Agassiz, 1829) na Baía de Pinheiros, litoral do Paraná, Brasil. Os peixes foram coletados mensalmente no período de junho de 2003 a maio de 2004, com rede de arrasto de fundo. De cada exemplar foram tomados os dados de comprimento total, peso total, sexo e peso da gônada. As seis fases de desenvolvimento ovocitário (ovogênese) e os cinco estádios de desenvolvimento ovariano (escala de maturidade) foram determinadas por análi… Show more

“…In auchenipterids, Trachycorystes galeatus (=Trachelyopterus galeatus) presented the same pattern of asynchrony between males and females (Silva & Viana, 2003). A similar condition was already recorded for other fish species as Piaractus mesopotamicus (Characiformes: Characidae) (Costa & Mateus, 2009), Cathorops spixii (Siluriformes: Ariidae) (Fávaro et al, 2005) and a number of marine species (Murua & Saborido-Rey, 2003).…”

“…When the number of organisms caught is higher than the number produced, it can be said that the stock is being overfished (Fonteles-Filho, 1989). However Stellifer rastrifer Among the species sampling in the present research, only B. marinus and C. spixii display demersal spawning and parental care (Fávaro et al, 2005). These reproductive strategies have a negative influence on populations' ability to recover, as egg development depends on oral incubation (Carvalho-Filho, 1999;Fávaro et al, 2005).…”

“…Normalmente, a pesca De acordo com a literatura, aparentemente existe um período reprodutivo único e amplo para os membros da família Ariidae, que se inicia na estação chuvosa e estende-se até o final do período de estiagem (Gomes & Araújo, 2004;Fávaro et al, 2005;Pinheiro-Sousa et al, 2015).…”
