Sea Around Us data users interested in learning how to perform a catch reconstruction update now have access to a suite of free video tutorials.
The step-by-step guides, available in English with carefully curated subtitles in Spanish, French, and Chinese (with more languages on the way), are presented in an easy-to-understand animated video format led by a researcher named Ola.

Extractive activity in international waters – including fishing, seabed mining, and oil and gas exploitation – should be banned forever, according to top scientists.
The high seas, the vast international waters beyond national jurisdiction, cover 43 per cent of the planet’s surface and two-thirds of its living space. Yet they remain largely unprotected and increasingly threatened by overfishing, climate disruption and the rising interest in deep-sea mining.

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 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.

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.
