The correct answer is: d) All of the above.
Fish farming in Arunachal Pradesh can be done in ponds, tanks, and rice paddies.
Ponds are the most common type of fish farm in Arunachal Pradesh. They are usually small, shallow, and man-made. Ponds are often used to raise carp, tilapia, and other freshwater fish.
Tanks are also used for fish farming in Arunachal Pradesh. Tanks are usually larger than ponds and can be made of concrete, fiberglass, or other materials. Tanks are often used to raise ornamental fish, such as goldfish and koi.
Rice paddies are another type of fish farm in Arunachal Pradesh. Rice paddies are flooded fields that are used to grow rice. Fish are often raised in rice paddies along with rice. This type of fish farming is called integrated rice-fish farming.
Integrated rice-fish farming is a sustainable way to produce both rice and fish. The fish help to control pests and weeds in the rice paddies. The rice provides shade and cover for the fish. Integrated rice-fish farming can help to improve soil fertility and water quality.
Fish farming is an important part of the economy of Arunachal Pradesh. It provides jobs and food for the people of the state. Fish farming also helps to protect the environment.
