In the heat of summer in central Greece, the Aristotle University of Thessaloniki hosted the 22nd FishBase and SeaLifeBase Symposium.
Titled “Fishes in Changing Ecosystems,” the two-day event started on September 2, 2024, with a full day dedicated to some of the overarching themes the Sea Around Us team is doing research on.

The growth and lifespan of Parvancorina minchami, small anchor-shaped animals that lived on the seafloor about 550 million years ago, resemble that of current marine invertebrates like golden shrimp and Baltic clam.
New research by a team at the Russian Academy of Sciences, Harvard University and the Sea Around Us initiative at the University of British Columbia shows that P. minchami’s longevity was about four years, that they could reach close to 20 millimetres in length, and that their pace of growth was similar to that of small recent invertebrates.

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.
