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.
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.
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
