The Atlantic chub mackerel ( Scomber colias ) is an ecologically and commercially important species supporting artisanal and industrial fisheries in West Africa. This study updates critical reproductive parameters for S. colias in Senegalese waters to inform stock assessment and sustainable management of small pelagic fisheries within the Senegalese Exclusive Economic Zone. Based on 1134 specimens monthly sampled from commerci...

Shellfish harvesting in Saloum Islands is crucial for economic and socio-cultural income, particularly for women. However, the industry is facing decline in stocks and harvested individuals, necessitating urgent shellfish assessment and mapping in the Saloum Delta. This study aimed to characterize and assess the distribution, diversity and abundance of mollusc species of commercial interest in the Saloum delta. The species col...

Senegalese and Mauritanian fisheries exploit the same species of white grouper but have different exploitation histories. In Senegal, white grouper has been fished for a very long time (since the 1970s), whereas it is relatively recent in Mauritania. In addition, Senegalese small-scale fishermen exploit this species in the Gambia. Nevertheless, mainly for practical reasons, all attempts to assess the status of the stock have,...

We investigate Sardinella aurita and Sardinella maderensis recruitment success relative to the variability of oceanographic conditions in Senegalese waters using generalized additive models ( GAM ). Results show that recruitment of both species is marked by a strong intra‐annual (seasonal) variation with minimum and maximum in winter and summer, respectively. Their interannual variations are synchronous until 2006 (recruitment...

The objective of this study was to assess the effect of environmental variations on the abundance of Sardinella aurita and Sardinella maderensis in Senegalese waters in the upwelling system. Monthly data indicating the abundance of sardinella were first estimated from commercial statistics, using Generalized Linear Model from 1966 to 2011. Abundance indices (AIs) were then compared with environmental indices, at the local scal...
