Traditional fishing methods in Manipur include:

Cast nets
Gill nets
Traps
Hand-lining

The correct answer is: Cast nets, gill nets, traps, and hand-lining.

Cast nets are a type of fishing net that is thrown into the water by hand. They are made of a lightweight material, such as nylon or cotton, and have a circular or semi-circular shape. When the net is thrown, it spreads out and traps the fish inside.

Gill nets are a type of fishing net that is made of a fine mesh. They are suspended in the water and fish are caught when they swim into the net and become entangled in the mesh.

Traps are a type of fishing device that is used to catch fish. They can be made of a variety of materials, such as wood, bamboo, or metal. Traps are usually baited to attract fish, and they can be set in a variety of locations, such as rivers, lakes, and oceans.

Hand-lining is a type of fishing method that is used to catch fish by hand. It is a simple method that does not require any special equipment. To hand-line, a fisherman simply casts a line into the water and waits for a fish to bite.

All of these methods are traditional fishing methods that are used in Manipur. They are all effective methods for catching fish, and they have been used for centuries.
