A recent worldwide decline of ocean fishery stocks has stimulated rapid growth in cultivated production of fish and shellfish, usually known as fish farming. ███████ ████ ███ █████ ███ ████████ ██████ ████ ██████████ ████ ███████ ████████ ████ ███████ ████████ █ ███████ ██ ███ ████ ███ █████████ █████ ██ ███████ ████ ██ ██████ ██████████ ██████████ ████ ███████ ████ ████████ ██████ ████ ████ █████████ ██ █████████ █████ ███████ ██████ ███
Intro topic ·
Fish farming (FF)
Decline in wild fish (ocean fishery stocks) led to more fish farming. Fish farming produces a large portion of the fish we eat.
Some experts' perspective ·
FF will restore wild fish populations
Critique ·
FF potentially both alleviates and causes decline in wild fish

FF can damage wild fish habitats
Intensive fish farming (designed to produce lots of fish) leads to a lot of waste and higher potential for diseases among fish. Wild fish habitats can be destroyed from that waste, those diseases, or the escape of farmed fish species that aren't native to the region.

FF requires using a lot of wild fish for food
The farming process for many species requires using more wild fish (by weight) than we get from harvesting the farmed fish.

Support for Critique (alleviates decline) ·
Can reduce incentive to capture or eat some wild fish species.
Can reduce prices of some fish, which deters efforts to capture wild versions of those fish. Some farmed fish species can provide alternatives to some other wild fish species.
Doubt ·
Benefits of FF for wild fish might be lost
Markets have developed for some wild-caught fish, despite availability of farmed alternatives.

Most farmed fish ███ ████████████
Unsupported. We don't know whether most farmed fish are carnivorous. We were only given examples of some species of carnivorous fish.

c
Pollution is currently ████ ████████ ██ ████ ████ ███████████ ████ ██ ████████████
Unsupported. We know that pollution does some damage to wild fish populations and we know that overfishing does some damage to wild fish populations. But we don't know of the two which one does more damage.
