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.

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.

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 of tropical fish. Thus, upon his return to Kiel University’s Institute of Marine Sciences, he decided to find out how fish grew; the idea was that if general patterns emerged, they could be applied to the many species in Indonesia and elsewhere in the tropics.
His doctoral dissertation was, consequently, built around identifying the factors that govern fish growth.
