Polar fish are less likely to die early, so they prioritize growth over reproduction

Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana Álvarez-Noriega at Monash University in Australia and colleagues, publishing May 25 in the open access journal PLOS Biology. This may have implications for the effects of climate change on the sustainability of fish populations.
