The correct answer is C. Pisciculture.
Pisciculture is the farming of fish. It is a branch of aquaculture, which is the farming of aquatic organisms. Pisciculture can be done in freshwater or saltwater, and it can be used to produce fish for food, sport, or ornamental purposes.
The word “piscculture” is derived from the Latin words “piscis,” meaning “fish,” and “cultura,” meaning “culture.” The word was first used in the 18th century, and it is now used in both the scientific and lay communities.
Pisciculture is a growing industry, and it is estimated that the global market for farmed fish will reach \$200 billion by 2025. The growth of the industry is being driven by increasing demand for fish as a source of protein, as well as by the development of new technologies that make pisciculture more efficient.
Pisciculture can be a sustainable way to produce fish, and it can help to reduce the pressure on wild fish stocks. However, it is important to ensure that pisciculture is done in a way that minimizes the environmental impact.
