Fish buffered from recent marine heatwaves, showing there’s still time to act on climate change

Fish buffered from recent marine heatwaves, showing there’s still time to act on climate change

Fish were surprisingly resilient to marine heatwaves before 2019, highlighting the need to keep seas from warming further, according to new research.

Keep growing – Fish’s growth is not reduced by spawning

Keep growing – Fish’s growth is not reduced by spawning

Contrary to what is stated in biology textbooks, the growth of fish doesn’t slow down when and because they start spawning. In fact, their growth accelerates after they reproduce, according to a new article published in Science.

Food quality matters for southern resident killer whales, UBC study states

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

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.

Food quality might be key for juvenile sockeye salmon growth and survival

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

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

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.
