Food quality matters for southern resident killer whales, UBC study states
If southern resident killer whales ate just low-lipid salmon, they would have to eat around 80,000 more Chinook salmon every year than if they just ate high-lipid salmon.
Expecting aquaculture to ‘feed the world’ may be unrealistic, UBC-led study shows
Trends in global aquaculture growth rates reveal that the 101 million tonnes of farmed fish intergovernmental bodies expect countries to produce by 2030 may be unrealistic.
Seafood farming’s growth rate has already peaked, and now it’s in decline
The growth rate of seafood farming worldwide peaked in 1996 according to new UBC research, highlighting the importance of rebuilding wild fish stocks to feed future demand.
New Fisheries Centre Research Report (FCRR)
Implementing CITES Appendix II listings for marine fishes: a novel framework and a constructive analysis
Food quality might be key for juvenile sockeye salmon growth and survival
The quality of food sockeye salmon eat along their migration routes is more important to their growth and condition than quantity, a new study has found, highlighting concerns about the effects of climate change on ocean conditions and salmon.
Expect shorter food chains in more productive coastal ecosystems
“We provided evidence for bottom-up omnivory in nutrient-rich temperate pelagic ecosystems, where food chain length is determined by the level of diatom production,” said Jacob Lerner. “This is very different from the global model for pelagic ecosystems.”
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.
New FCRRs: Historical Ecology in Burrard Inlet and Reconstructing the pre-contact shoreline of Burrard Inlet
These two new Fisheries Centre Research Reports will help us understand the overpowering changes that colonial settlement and development has had on the marine ecosystems surrounding the Lower Mainland area of British Columbia.
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.
Farmed seafood supply at risk if we don’t act on climate change
If we continue to burn fossil fuels at our current rate, the amount of seafood able to be farmed sustainably will increase by only 8% by 2050, and decline by 16% by 2090.
