Farming Atlantic Salmon in Tasmania

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.

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.

It takes about six hours, departing from Vancouver, to reach the Bamfield Marine Science Centre, where was held the 45th annual Pacific Ecology and Evolution Conference (PEEC). Three of those hours consist of sailing on the MV Frances Barkley – a 65-year-old heritage ship originating in Norway that started its current route in 1990 – through the Alberni Inlet from Port Alberni to Bamfield, almost reaching the open ocean in Barkley Sound.
