With billions of people depending on seafood for protein, determining the answer has big implications.

The pair restarted their work in Massachusetts with about 400 brook trout reared for up to eight months in tanks. The scientists kept some of the fish in waters set at 59 degrees Fahrenheit while others at 68 degrees Fahrenheit. All were fed the same diet.

By the end of the experiment, the difference was stark. The trout raised in warmer waters were on average less than half the size as the other fish.

    @Neon yeah I think you need to actually read the article before you @ me about this stuff. You’re constructing a massive straw man involving embargos and local companies that has nothing to do with the real situation.

    The Feedback report takes a different perspective, recommending the Norwegian government to “halt the growth of Norway’s salmon farming sector” and “ensure the domestic farmed salmon industry does not undermine its global development goals.”

    The NGO based its calculations on public commercial data and company reports by the four companies that together supply close to 100% of the feed used in Norwegian salmon farming: Mowi, Dutch-owned Skretting, U.S.-based Cargill and Denmark-based BioMar. According to Feedback’s analysis, all of these companies sourced fish oil made from small pelagics caught in FAO’s Major Fishing Area 34, located off West Africa.
