Fish that live on or near the seafloor -known as demersal or groundfish- barely feel the impact of marine heatwaves, according to new research that highlights the need to keep seas from warming further.

Climate change-induced droughts and fish kills affect larger fish more severely than smaller individuals, according to new research.
In a paper published in Environmental Biology of Fishes, researchers from Leiden University, Sportvisserij Zuidwest Nederland and the Sea Around Us initiative at the University of British Columbia compared evidence from drought-induced fish kills in the Netherlands, fisheries management literature and multiple physiological studies. They confirmed that when water gets warmer and deoxygenated, larger and older individuals within a species tend to die in greater numbers than their smaller and younger counterparts.

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.
On April 6, 2023, members of the FISHGLOB Consortium offered a conference at the University of British Columbia’s Michael Smith Labs Theatre to present some of the findings of three years of work on issues related to marine species assemblages’ homogenization/differentiation through time, consequences on fish stocks shared across countries, and fishery management.
The Sea Around Us, together with the French Embassy in Canada, the University of Montpellier, FRB-CESAB: Centre de Synthèse et d’Analyse sur la Biodiversité and Rutgers University, is hosting the conference Fish biodiversity facing global change.
The event, which will take place on April 6, 2023, from 2-3 pm, at the University of British Columbia’s Michael Smith Labs Theatre, will present activities of the FISHGLOB consortium which has collected and combined a unique data set of scientific bottom trawl surveys conducted regularly during the last decades across the planet.
