The physical relief that temperate fish like cod and Atlantic herring experience after they spawn for the first time allows them to breathe in more oxygen and develop a voracious appetite, all of which leads to a rapid increase in body weight.

AI-powered data-limited stock assessment method more accurate than ‘gold standard’ in predicting sustainable fisheries catches
A recent update introduced to the CMSY methodology used to assess the status of fish stocks has proven to more accurately predict the catch that a population can support than highly-valued data-intensive models.

Egyptian Mediterranean fisheries in urgent need of better management
Egyptian fisheries need to be better managed to secure the overall health of the Mediterranean Sea’s marine living resources, new research has found.
In a recent paper in the journal Ocean and Coastal Management, researchers with the Sea Around Us initiative at the University of British Columbia’s Institute for the Oceans and Fisheries and the Arab Academy for Science, Technology and Maritime Transport reconstructed Egypt’s marine fisheries catches from the Mediterranean in the last 100 years and found strong evidence of resource overexploitation. Such overexploitation has pushed fishers to go farther and deeper, increasingly resorting to species lower in the food chain.
Overfishing and climate change impacts on New Zealand’s fish populations were hidden – until now
Pelagic-oceanic fish commonly caught in warmer waters, such as skipjack tuna and blue mackerel, have been increasing in New Zealand’s waters since the 1950s, while cold-water species such as southern bluefin tuna display strong reductions in overall catch from the 1970s onwards, new research has found.
Market-based solution makes the case for blue carbon
Over 120 million tonnes of carbon dioxide equivalent could be sequestered every year by 2050 by applying a market-based solution (MBS) to global fisheries that would allow fishers to decide whether – at certain times – it is more profitable to go fish or to remain at port.
