Protecting 30 per cent of the ocean by 2030 would barely impact fisheries
Sea Around Us presents a multi-objective solution that could lead to the protection of 89% of the ocean’s Representative Biodiversity Areas and 89% of threatened species or about 860 species, all while maintaining access to fishing grounds that provide 89% of the global catch.
New model helps predict climate change-induced early spawning by fish
Fisheries managers and researchers may now predict how early fish will spawn in response to warming waters due to climate change, both in the oceans and in freshwaters.
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.
What really makes fish become sexually active
“What I think really makes fish spawn for the first time is the increasing oxygen stress that growing fish experience,” Daniel Pauly said
Dr. Daniel Pauly’s extraordinary life and work revealed in new book
Dr. Daniel Pauly is the world’s most-cited fisheries scientist, but life for the UBC professor has been far from easy. Now, readers can learn more in his biography, The Ocean’s Whistleblower.
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.
