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.

Support for Critique (causes decline) · 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.

Support for Critique (causes decline) · 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.

The information in the passage ████ ████████ ████████ █████ ███ ██ ███ █████████ ███████████

a

Wild fish require █████████ █████████ ████ ██████ ████ ███

Unsupported. While we have strong evidence to support the idea that wild fish and farmed fish are consuming different foods, we don't know whether they have different nutritional requirements. The passage only details some of the nutritional requirements of farmed fish.

7%
b

It is more ██████████ ██ ████ ███████ ████ ██ ████████ █████████ ███ ████ ████ ██ ████ ███████ ████ ██ ███████

Unsupported. Profit is revenue minus cost. We have no information on how much revenue catfish, milkfish, and carp can bring in relative to salmon. Even though the passage contains information which suggests that it's more expensive to farm salmon without knowing the price that salmon can fetch in the marketplace, we cannot speak to its profitability.

c

The farming of ███████ ███ ███████ ███████ ████████ ██ ████ █████████████ ██████ ██ ███ ███████ ██ ███ ███ ████████

Unsupported. The passage talked about farming tilapia and channel catfish as a way to reduce pressure on wild cod and haddock. It did not talk about the farming cod and haddock.

1%
d

A growing number ██ █████████ ███ ████████ ███████████ ████ ██ ███████ ███████ ██ ██████████ ██ ██████ █████

Supported. The passage states that farm fish can be beneficial by taking pressure off of wild fish. But then, the passage states that this benefit is being lost and that niche markets have started to develop for several species of wild-caught fish even though production of farmed substitutes has increased. Why would that be? The likely explanation is that consumers are choosing wild-caught fish in preference to the farmed version.

e

Noncarnivorous fish in ███ ████ █████████ ██ ███ ███████ ████ ████ ████ █████ ██████ ████████████ ███

Unsupported. The passage contained no information about wild vegetarian fish.
