Global warming is expected to push stocks of highly migratory straddling species in the Indo-Pacific, such as chub mackerel, from EEZs toward the high seas by mid-century. Photo by Matsumomushi, Wikimedia Commons.
Sea Around Us website users will now be able to access the Mean Temperature of the Catch (MTC), as an ecosystem indicator derived from the reconstructed catches of a large fraction of the 283 Exclusive Economic Zones (EEZs) presented on our website.

Destructive fishing practices and inadequate management allowed industrial fisheries operating in the waters of Saint Pierre and Miquelon to dump about 80,000 tonnes of fish back into the ocean from 1950 to 2022, with authorities failing to track the wasteful practice. This is enough fish to fill 32 Olympic-sized pools.

If humanity wants to continue to derive healthy nutrition from wild-caught fish – as 40 per cent of the global population currently does – it is crucial that fisheries managers and marine conservationists start using the same metrics to evaluate the effectiveness of both sustainable fisheries measures and the establishment of marine protected areas.

In a world where the dramatic effects of global warming on land dominate news headlines, there is a tendency to overlook the massive impacts of warming and deoxygenation on oceans and freshwater ecosystems. However, the effects of climate change on the species that inhabit these ecosystems are, in some respects, more drastic than the challenges faced by terrestrial animals.

The global fishing industry should be appropriately represented within climate change mitigation frameworks, where it remains overlooked, a new letter published in Science suggests.
