Anticipating the Effects of Increasing Rivers’ Water Salinity for Sustainable Conservation of Tilapia Resources in Rural Coastal Zone of Benin, West Africa

The current research aimed at using the application of multi-factor models to support fisheries management decisions for successful resources’ conservation. study was based on tilapia species Coptodon guineensis, which is among most widely exploited in Benin coastal zone. In an attempt suggest conservation strategies, phenotypic variability 356 accessions this assessed relation with water salinity, and several interactions. fish were collected through small-scale experimental fishing cast nets gillnets. findings indicated that salinity observed sampled rivers due, proportions ranging from 0.13% 47%, sea surface (SSS) Atlantic Ocean, suggesting a leading inland origin these rivers. evidence also showed populations have been relatively adapted increasing species*river type species*fish sex interactions had significant effects characteristics rather than river type*fish interaction. For efficient populations, two areas (Lake Nokoué Porto-Novo lagoon vs Lake Toho Grand-Popo lagoon), could be considered species.
