1. Segregation of total costs into its fixed and variable components is always a daunting task to do. 2. Fixed costs are unlikely to stay constant as output increases beyond a certain range of activity. 3. The analysis is restricted to the relevant range specified and beyond that the results can become unreliable. 4.
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
Aquaculture is the most rapidly expanding food industry in the world [7] as a result of declining wild fisheries stocks and profitable business. [2] In 2008, aquaculture provided 45.7% of the fish produced globally for human consumption; increasing at a mean rate of 6.6% a year since 1970.

The Taiwanese ornamental fish and shrimp industry is significant with more than 250 commercial operations, ~200 of them with operations in Pingtung County.

In 2018, Canada's fishing industry was worth $36.1 billion in fish and seafood products and employed approximately 300,000 people. [1] Aquaculture, which is the farming of fish, shellfish, and aquatic plants in fresh or salt water, is the fastest growing food production activity in the world and a growing sector in Canada.
The top aquaculture products exported include shrimp, fish and seaweed. [ 2 ] Aquaculture in Indonesia has seen a tremendous growth in its contribution to fish supply in Indonesia, increasing from 10.6% in 1960 to 40.2% in 2014, [ 1 ] and looks to surpass the output of capture fisheries by 2026 under business as usual scenarios.
