Fish populations and the humans that depend on them for food will continue to feel the brunt of warming waters from climate change.

A recent study by researchers at the Sea Around Us – Indian Ocean, based at the University of Western Australia, the Changing Ocean Research Unit at the University of British Columbia and the University of Miami, shows that even with strong climate mitigation efforts, maximum catch potential is expected to fall by 58–92 per cent in the Pacific Islands and 65–86 per cent in Southeast Asia by the mid to end of the 21st century. These losses will likely result in fisheries failing to meet key micronutrient requirements in these regions’ coastal populations.

Global North’s growing appetite for farmed salmon imperils communities’ access to local fish

The growing appetite for expensive farmed salmon can leave coastal communities struggling to access affordable local fish like sardines and anchovies, new research published in Science Advances shows.

The paper, co-authored by researchers with Oceana and the Sea Around Us initiative at the University of British Columbia’s Institute for the Oceans and Fisheries, exposes the global aquaculture sector’s growing dependence on wild, small pelagic fishes which are frequently caught, processed, and ‘reduced’ to fishmeal and fish oil. Almost the entirety of the production of fishmeal and fish oil, that is, 87 per cent and 74 per cent respectively, is used to feed farmed fish.

After the collapse of herring and cod stocks in the western Baltic Sea, flatfish such as plaice, flounder, and dab now dominate the catch. However, they can't replace the lost catch of cod and herring. Photo by Ilka Thomsen, GEOMAR.

Fisheries research overestimates fish stocks

As the abundance of global fish populations continues to deteriorate, top fisheries researchers are calling for simpler yet more accurate stock assessment models that avoid overly optimistic scientific advice, which ends up encouraging overfishing.
