  >> We badly need some sort of industrial fish farming at a large scale. > They're doing that. IIRC, most farmed fish are fed with fish meal, which is basically less-desirable wild-caught fish, so fish farming does not take the pressure off the oceans as much as you'd think. https://en.wikipedia.org/wiki/Fish_meal https://en.wikipedia.org/wiki/Fish_meal > The production and large-scale use of fishmeal are controversial. The lucrative market for fishmeal as a feed encourages corporate fisheries not to limit their yields of by-catch (from which fish meal is made), and thus leads to depletion of ecosystems, environmental damage, and the collapse of local fisheries. https://en.wikipedia.org/wiki/Fish_farming https://en.wikipedia.org/wiki/Fish_farming > Farming carnivorous fish, such as salmon, does not always reduce pressure on wild fisheries. Carnivorous farmed fish are usually fed fishmeal and fish oil extracted from wild forage fish.
