Researchers deploy a new tool to study Chinook salmon fat content on the Fraser River
A Chinook with a short migration to Harrison Lake may offer half the calories to a resident killer whale as a similarly sized Chinook headed to the headwaters of the Fraser River.
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.
PROFILE: Saving British Columbian streams, rivers and lakes for fish
The Applied Freshwater Ecology Research Unit’s (AFERU) job is to find ways to conserve freshwater species, test effectiveness of current conservation strategies, and understand how freshwater fish are responding to changes in their habitats.
“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.
Marine heatwaves could wipe out an extra six per cent of a country’s fish catches, costing millions their jobs
Extremely hot years will wipe out hundreds of thousands of tonnes of fish available for catch in a country’s waters in this century
Countries likely missing out on revenue from catch share fisheries
Despite harvesting an estimated global value of US$17.7 billion worth of fish, many catch share fisheries may be paying little or no royalties on their harvests, with countries likely foregoing this potential source of revenue.
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.
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.
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
