Farmed fish is probably not too bad by comparison but.. wild caught fish hell no. We’re speed running fucking up the ocean ecosystem and ruining the aquatic biosphere. It always alarms me when I see a change to the species of fish used in “generic budget oven-cook battered fish fillets”. It doesn’t even seem possible to make wild catch fishing sustainable, unlike every other form of animal husbandry where you could argue it’s more of a technical challenge.
Hmm now I realise I’m a hypocrite. Think I’ll stop eating fish
Farmed fish is often worse. The fish are kept in small pens and given tons of antibiotics, polluting the local water. Sometimes those non-native fish escape the pens and interbreed with native species. They are also less nutritious than wild fish, at least when it comes to salmon.
