The most commercially important marine species in Belize show signs of overexploitation, according to a recent report co-authored by members of the Sea Around Us.
In over 30 years of continuous operation and development, FishBase has become one of the largest and most extensively accessed online public resources in the history of scientific research. A new study reveals it is also one of the most highly cited databases.

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.

Warmer water than that to which a fish is used becomes an aggressor of sorts that impacts internal biochemical processes and forces the fish to stop growing at a smaller size than it would normally do in optimal habitat conditions, new research shows.

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.
