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.
IOF researchers find simple solution to Kuwait’s blood snapper woes
The change could help repopulate Malabar blood snapper, whose numbers dropped by 95% between 1995 and 2009
Tilapias are not precocious, they are just resilient
Tilapias living in crowded aquaculture ponds or small freshwater reservoirs adapt so well to these stressful environments that they stop growing and reproduce at a smaller size than their stress-free counterparts.
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”.
STUDENT PROFILE: Samantha Ramirez
I’m creating a model that will predict the hypoxic conditions of freshwater streams years from now. This will help governmental organizations know where to focus their conservation efforts in terms of which streams are going to be the most impacted by our changing environment, said Ramirez.
