Data confirm link between respiratory stress and fish reproduction
A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active – and spawn for the first time – in response to growth-induced respiratory stress.
Estimating the biomass of commercially exploited fisheries stocks left in the ocean
This new Fisheries Centre Research Report (FCRR) presents the key results of a multi-year activity of the Sea Around Us devoted to assessing the status of marine fisheries globally.

“Race to jellyfish” leaves Mexican fishery in turbulent water
Over the last 20 years, interest in cannonball jellyfish in the Gulf of California, Mexico exploded when Chinese investors saw that the area was a hot spot for the species.

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.
As fishing effort grows, catches decline in the Mozambique Channel region
Researchers found that effective small-scale fishing effort in the entire Mozambique Channel region grew slowly but steadily from around 386,000 kWdays in 1950 to around 23 million kWdays by 2016, with Mozambique and Madagascar dominating the upward trend.
A few missing fish: US West Coast recreational and discarded catches
United States of America lacks international reporting of recreational catches and fish discarded at sea, which may hinder proper ecosystem-based management efforts
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.
