Twenty-six fish and invertebrate populations that live in the waters of eight West African countries are likely overfished or at risk of being overfished, a new Fisheries Centre Research Report reveals.

Preliminary results from the application of the CMSY and LBB stock assessment methods to fish populations in the EEZs of Cape Verde, The Gambia, Guinea, Guinea-Bissau, Liberia, Mauritania, Senegal and Sierra Leone, indicate that some stocks – such as that of cassava croaker off the coast of Liberia – are strongly overexploited.

Bluefin tuna, swordfish and Atlantic mackerel are among the fish species considered commercially extinct or extirpated on the Turkish side of the Marmara and Black Seas.

A new study by researchers with the Sea Around Us initiative at the University of British Columbia, Mersea Marine Conservation Consulting, Turkey’s Central Fisheries Research Institute and the Institute of Marine Sciences and Management at the University of Istanbul, found that 17 fish species have been extirpated and 17 are commercially extinct in Turkey’s Black Sea, while 19 have been extirpated and 22 went commercially extinct in the Sea of Marmara.

The food and nutrient security of billions of people worldwide depend on fish being treated as a domestic public health asset instead of a commodity.

A new paper by researchers with the Sea Around Us – Indian Ocean initiative at the University of Western Australia and the Sea Around Us global initiative at the University of British Columbia reviews evidence to back the urgent need to develop health- and nutrition-focused fisheries policies that drift away from current export-oriented, profit-maximizing policies.

The United Kingdom has a unique opportunity to start rebuilding its fish stocks by taking advantage of the slowdown in commercial fishing caused by the COVID-19 pandemic and ongoing Brexit negotiations that should lead to new policy and legislation.

A new paper by researchers with the University of Southampton, the GEOMAR Helmholtz Centre for Ocean Research and the Sea Around Us initiative at the University of British Columbia presents a science-based pathway for decision-makers to develop a holistic approach in fisheries management by harnessing the present moment in which threatened stocks are seeing fishing pressure reduced to levels not seen since World War II.
