(Salt water) fish farming is still hunting on an industrial scale because the farmed fish are mostly carnivorous and are fed with feed derived to a large part from hunted fish. It's mostly a tool to strip the oceans even harder (with fish farms converting undesirable catch into species people like to eat, everything becomes a target)
- giancarlostoro 6y agoThey should farm the prey too then? I still wonder where those mice that pet snakes eat come from. Never had a pet snake so I don't know much about them.
- oblio 6y agoYeah, I agree. Otherwise it's like saying we can't grow corn because you need water, minerals and these days, fertilizers. When we really want to, we can take care of the whole chain.
- usrusr 6y agoIf you continue that line of thought long enough you end up declaring the entirety of the world's oceans one big fish farm and truly sustainable fishing that doesn't deplete populations your method of farming.
- giancarlostoro 6y agoThe alternative is farming fish you can feed other things you can grow instead. Ultimately artificial meats and what have you will be the ultimate goal to sustain the whole system.
- globuous 6y agoI don't understand why we eat carnivorous fish. It'd be like feeding on lions... I read some of piketty's book, capital and idéologie, and he sources work that show that if India and China have historically had a greater population, it's because Europeans love meat. And feeding a population on meat requires much more agricultural space than feeding on veggies and cereals alone. I had always wondered why it was, and I liked this explanation!
- usrusr 6y agoBecause in the open water of the oceans, not only the herbivorous level of the food chain is on the plankton scale but also the first carnivorous level or levels. The small fish that are eaten by the larger fish that we eat are already feeding off carnivores.
