Forty-year-old concepts around fish respiration regain prominence in light of climate change

Before Dr. Daniel Pauly, now the principal investigator of the Sea Around Us initiative at the University of British Columbia, became a doctoral student, he spent two years doing fisheries work in Indonesia. Having done his academic studies in Germany, he was surprised to discover a near absence of information on the growth…

Respiratory stress response that stunts temperate fish also affects coral reef fish

In a recent paper in the journal Fishes, researchers at the University of British Columbia’s Sea Around Us initiative gathered additional evidence supporting the idea that fish become sexually active – and spawn for the first time – in response to growth-induced respiratory stress, which intensifies in warmer, low-oxygen environments. By assembling and analyzing data on the…

Fish become ‘young’ again after spawning

The physical relief that temperate fish like cod and Atlantic herring experience after they  allows them to breathe in more oxygen and develop a voracious appetite, all of which leads to a rapid increase in body weight. New research published in Environmental Biology of Fishes turns on its head the widespread notion that…

FishBase and SeaLifeBase 2021 Anniversary Symposium – Magnifique!

The always buzzing Paris – which did it best to exhibit its usual accelerated rhythm even in pandemic times -, hosted on September 6-7, 2021, an equally dynamic FishBase and SeaLifeBase Symposium at the Grande Galerie de l’Évolution of the National Museum of Natural History. One presentation after the next,…
