It depends on what form of aquaculture. species such as salmon and those that are carnivorous and actually require feed derived from wild fish. The amount of captured fish to raise farmed fish is massive (something like a ratio of 4:1) this then is a huge issue for the sustainability of wild fish stocks.
Beyond this many of the farms can be environmentally degrading affecting local fish with disease, escapment etc. additionally the seabed can become a wasteland. It should be noted that the extent of effects are limited by the location and size of farms.
1.Aquaculture is related to freshwater, mariculture is identified with seawater. 2. Aquaculture is the branch involving the whole spectrum of fish products. But Mariculture pertains to a branch of aquaculture. 3. Aquaculture is farming of salt water and freshwater organisms like finfish, crustaceans molluscs and aquatic plants. Mariculture, on the other hand is a specialized wing of aquaculture that is undertaken in marine environments.

Capture fishing is where fish is obtained from natural sources, and mariculture involves having marine fish for commercial purposes, while aquaculture involves production of aquatic animals considered of high economic value.

Fish farming is the principal form of aquaculture, while other methods may fall under mariculture. It involves raising fish commercially in tanks or enclosures, usually for food.
