Now a day, there is an increasing demand for fish or fish protein, and the result is widespread overfishing in wild fisheries. Fish farming or pisiculture offers a fish marketers another source. However, the farming of carnivorous fish, like as salmon, does not always reduce pressure on wild fisheries, since carnivorous farmed fish are generally fed from fishmeal or fish oil that is extracted from wild forage fish. That is why, the salmon fish can consume in weight more wild fish than they weight themselves.
