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…

A recent update introduced to the CMSY methodology used for assessing the status of fish stocks has proven to be more accurate in predicting the catch that a population can support than highly-valued data-intensive models. In a paper published in the journal Acta Ichthyologica et Piscatoria, the international team of researchers that shaped the…

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. The paper is a technical comment by Dr. Rainer Froese, senior scientist at the Geomar Helmholtz…

Climate change disrupts core habitats of marine species

Climate change will bring about significant distributional reorganization of marine life with a net range loss of core habitat for the majority of marine species, a new study led by researchers at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, Bremerhaven (AWI) and co-authored by the AquaMaps…
