As climate change continues to warm and deoxygenate ocean water, the size of fish, aquatic molluscs and crustaceans is showing a concerning reduction pattern. This pattern manifests a life history in which the animals exposed to rising temperatures grow fast when they are young but mature at smaller sizes than before and their final body sizes are also smaller than they used to be.
The Sea Around Us PI, Dr. Daniel Pauly, and communications officer, Valentina Ruiz-Leotaud, have produced a new Fisheries Centre Research Report titled Marine and Freshwater Miscellanea V.
As its four predecessors, this document presents a diverse range of topics that offer substantial contributions to the field of fisheries science and which, if not published as an FCRR, might have remained stored away in individual researchers’ desks or computers.

The Sea Around Us principal investigator, Dr. Daniel Pauly, presented his Gill Oxygen Limitation Theory (GOLT) at the 9th Conference of the European Society for Evolutionary Developmental Biology held in Helsinki on June 24-28, 2024.
Cover of the Journal of Fish Biology. June 2024.
A recent paper authored by the Sea Around Us’ PI, Dr. Daniel Pauly, research assistant, Elaine Chu, and Dr. Johannes Müller from Leiden University, has made the cover of the June print issue of the Journal of Fish Biology, where it was introduced by a brief essay in the ‘Between the Covers’ section. The image that illustrates it is that of a large mythical sea creature known as an Aspidochelone, which appeared in a French bestiary around 1270 A.D.

Urea – the main component of human urine – plays an important role in the timing of maturation of sharks, rays and other cartilaginous fish.
A new study by researchers with the Sea Around Us initiative at the University of British Columbia’s Institute for the Oceans and Fisheries found that high urea concentrations common in cartilaginous fish, particularly oviparous marine species, allow them to mature and begin to reproduce at a larger fraction of their maximal size.
