Small pelagic fish species contribute substantially to the food security and livelihoods of local communities in developing countries. In West Africa, and particularly in Benin, small pelagic fisheries attract many migrant fishers who are key actors in the sector. This study assessed the characteristics and sociocultural impacts of the small pelagi...

Recognizing two decades of failure to achieve global goals and targets, parties to the Convention on Biological Diversity are in the final phase of negotiating a Post‐2020 Global Biodiversity Framework for the conservation, sustainable use and benefit sharing of biodiversity. The framework attempts to set out pathways, goals and targets for the nex...

Small pelagic fish (SPF) are among the most traded fishery products in small-scale fishing in coastal areas in low-income countries. Small-scale fisheries play a key role in the supply of fish products and form an integral component of the world’s fish production. However, due to post-harvest losses, distribution, and marketing issues, most SPFs st...
