A widely debated topic in biology and fisheries sciences is the role of oxygen in the growth of fishes and other water-breathing animals. According to new research, developmental changes in individual fish and experimental errors are the causes of inconsistencies that have erroneously been linked to the Gill Oxygen Limitation Theory (GOLT), developed to explain the influence of oxygen uptake on fish growth.
The Sea Around Us initiative turned 25 years old in July 2024.
To mark this milestone, the team produced a large poster highlighting some of the research accomplishments that turned the project into a reputable voice when it comes to fisheries data, and fish population management and conservation.

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 4 billion tonnes of marine organisms that global fisheries extracted from the ocean between 1960 and 2018 resulted in the depletion of over 560 million tonnes of essential nutrients vital to ecosystem health, new research has found.

Having spent a big portion of his professional career in the Global South, the Sea Around Us principal investigator, Dr. Daniel Pauly, quickly learned how difficult and onerous it is to access scientific literature in the region, even when working at renowned universities or institutes.
The effort that researchers working in countries outside North America, Europe and Australia have to make to write their dissertations, papers and other scientific contributions would be unimaginable for their peers in the Global North. From outdated library collections to poor bandwidth Internet connections, downloading a PDF of a recent publication for free with the click of a few buttons is unheard of in many places. If payment and delivery are required, then the task may become even more difficult.

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 of 2025, about 75 per cent of the Sea Around Us team is comprised of women and in the past 25 years, of the over 200 people from more than 40 countries who have worked for the project, 59 per cent have been women.

The Quantitative Aquatics and Sea Around Us teams lament the passing of W.N ‘Bill’ Eschmeyer (1939-2024), the founding editor and namesake of the Eschmeyer’s Catalog of Fishes (ECoF).
