Wealthier countries face challenges from exces...
A new study published in PLoS Biology found that most fisheries management regimes are lagging behind international standards, highlighting the need for transparent policy-making processes. The research assessed global fisheries management practices and evaluated their effectiveness in ensuring sustainability.
A new study finds nearly a doubling of illegal fishing in the Northeast multispecies groundfish fishery, with 12-24% annual harvest taken illegally. The study recommends a 'smart compliance policy' to combat noncompliance and protect fish stocks.
Researchers found that juvenile bluefin tuna from both regions return to their birthplace to spawn, contradicting previous assumptions about fish migration patterns. This study has significant implications for managing bluefin tuna fisheries in the Mediterranean and North Atlantic.
A study finds that catch shares can reverse fisheries collapse, with nearly a third of open-access fisheries collapsing compared to half for those managed under catch share systems. Catch shares create incentives to protect fish populations and reduce bycatch, leading to better biological outcomes.
The Inter-American Tropical Tuna Commission's failure to adopt effective conservation measures is threatened by rising pressures from fishing fleets and nations demanding increased fleet sizes. Urgent action is needed to protect tuna stocks, including time and area closures and research into fish aggregating devices.
