Extremely hot years will wipe out hundreds of thousands of tonnes of fish available for catch in a country’s waters in this century
Food for seals and other Arctic predators is shrinking — literally
Unchecked climate change may leave some Arctic predators, such as seals and whales, surviving off of marine “junk food”.
High cod catches could have been sustained in Eastern Canada for decades, simple stock assessment method shows
The assessment model demonstrated that if Canadian authorities had allowed for the rebuilding of the stock of northern Atlantic cod off Newfoundland and Labrador in the 1980s, annual catches of about 200,000 tonnes could have been sustained.
Getting a step closer to understanding how Chinook salmon live
Stable isotope analysis can peel back the curtain to give scientists a view of where fish spend their time, what they’ve been eating, and how they are interacting with other species.
China and the E.U. aren’t the only ones to blame for harmful fisheries subsidies
“Don’t think that just because you’re not providing six billion dollars that you’re not impacting, or potentially impacting the sustainability of the fish stock.”
Ecosystem modelling indicates that adding fertilizer to water reservoirs pays off
In the simulated Arrow Lakes Reservoir, fish fared better when nutrients were added to the water, regardless of whether the water flow was high or low.
Small-scale fisheries can back food security efforts in Arabian sea countries
Countries surrounding the Arabian Sea should empower well-managed artisanal and subsistence fisheries to back food security efforts, a new Sea Around Us study suggests.

Fisheries managers should not abuse Maximum Sustainable Yield
The Sea Around Us’ Daniel Pauly, and Rainer Froese, senior scientist at the GEOMAR Helmholtz Centre for Ocean Research, talk about their recent paper “MSY needs no epitaph—but it was abused”.
