Indian Ocean fisheries are vital for global nutrition as they provide 12 per cent of wild-caught seafood worldwide which, in turn, corresponds to nearly 30 per cent of all calcium from seafood, 20 per cent of vitamin A, 15 per cent of iron, and 13 per cent of vitamin B12.
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.
