Explanation:

Fish Farming or pisciculture involves raising fish commercially in tanks or enclosures such as fish ponds, usually for food. It is the principal form of aquaculture, while other methods may fall under mariculture. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, tilapia, salmon, and catfish.[1]

Demand is increasing for fish and fish protein, which has resulted in widespread overfishing in wild fisheries. China provides 62% of the world's farmed fish.[2] As of 2016, more than 50% of seafood was produced by aquaculture.[3]

As we consider resource utilization in our future food supply, quite clearly salmon offers the promise of producing a lot more food with a lot less input. This makes sense. For a few reasons, fish are the most efficient of farm animals. They don't use any energy to maintain their body temperature as land animals must.
