Influence of maternal effects and temperature on fecundity of Sebastes fasciatus on the Flemish Cap ; Influencia de los efectos maternales y la temperatura en la fecundidad de Sebastes fasciatus en Flemish Cap

The conservation of a sufficient reproductive potential of an exploited stock is one of the goals of fisheries management, as it ensures sustainable productivity. However, there is evidence that spawning stock biomass (SSB) does not represent well the variation in stock reproductive potential, often leading to impaired stock-recruitment relationships. In this study we show that fecundity of Sebastes fasciatus on Flemish Cap is not proportional to SSB and shows temporal fluctuation influenced by maternal effects. Females were collected in 23 research surveys between 1996 and 2020. An autodiamet... Mehr ...
