Answer 1

Hint: Rearing of fishes is called pisciculture. Fishes are very nutritious to the body. It is a source of molecules that are regarded as the building blocks of the body. It also has many medicinal values as well.

Complete answer:
Fishery is the industry devoted to the catching, processing and selling of fish, shellfish or other aquatic animals. Freshwater fishes are Catla, Rohu and common carps, whereas marine fishes are Hilsa, Sardines, Mackerel and Pomfrets. Pisciculture is rearing, catching, and management of fishes. India ranks ${6^{th}}$ in fish production all over the world. The blue revolution was the main reason that increased fish yield in India.
Importance of fishes:
1) Fish is an excellent source of protein, and contains very less amount of fat and minerals. They also carry vitamins A and D.
2) Some fishes are also used to control the spread of diseases like malaria by feeding upon their larvae. Example: Gambusia fish eat the mosquito larvae present in water bodies.
3) Fish oil: It is extracted from the liver of the shark, sawfishes. Fish oil is the rich source of Vitamin A, D, E and C.
4) Fish flour: It is highly nutritive food and prepared by a solvent extraction process easily digested by infants of 3-4 months.
Thus, the correct answer is option A.

Note: Aquaculture is little different from pisciculture as it involves the cultivation and breeding of both aquatic plants and animals. It is not confined to fishes.
