A. Salmon and rohu
B. Salmon and catla
C. Catla and magur
D. Rohu and catla

Answer 1

Hint: India is also an important country that produces fish through aquaculture in the world. The three main Indian fishes, such as mrigal (Cirrhinus mrigala), catla (Catla catla) and rohu (Labeo rohita) increases the size of making to the range of 70 to 75 percent of the net freshwater carp production.

Complete Answer:
- To answer this question, first, we need to know about the fish production. Fish are a very high source of proteins and have great nutritional value. Fish production was initially dependent on fish capturing.
- But many of the caught fishes were utilized for industrial purposes and were rarely taken as food by humans. So, a backup method to raise the fish production was confined to farming of commercially vital aquatic organisms. This is called aquaculture.

Now, let us find the solution from the option.
- Salmon farming is not viable in India as it is a cold water fish that lives in ocean waters between 4 to 15 degrees Celsius.
- Farming of the Magur variety has been banned from 2000 because of its harmful impact on indigenous varieties of fish and the fact that it was not good for human health.
- India is the third largest producer of fish in the world. Fishes reared in the culture fishery in - India are Rohu (Labeo rohita) and Catla (Catla catla). Apart from these fishes, mrigala (Cirrhinus mrigala) is also largely reared in India. They belong to the Cyprinidae family.

Thus, the correct option is D i.e. Rohu and catla.

Note: Half of the fish absorbed today is increased worldwide by fish farming. A few of the regular fish species that are cultivated are halibut, cod, tuna, salmon and trout. The aquafarms can be in the structure of mesh enclosures grown in water or concrete cages on land. The fish farms can harm the ecosystem by invasive species, contaminated diseases and pollutants.
