The correct answer is: d) All of the above.
Bamboo traps, throw nets, and gill nets are all traditional fishing gear used in Assam. Bamboo traps are made by weaving bamboo strips together to form a cage. The trap is then baited and placed in the water. When a fish swims into the trap, it becomes trapped and cannot escape. Throw nets are made of a lightweight material, such as nylon, and are thrown into the water to catch fish. Gill nets are made of a fine mesh that is suspended in the water. When a fish swims into the net, its gills become entangled in the mesh and the fish is unable to escape.
Bamboo traps are a traditional fishing method that has been used in Assam for centuries. They are simple to make and use, and they are effective at catching a variety of fish. Throw nets are another traditional fishing method that is used in Assam. They are more versatile than bamboo traps, as they can be used to catch a wider variety of fish. Gill nets are a more modern fishing method that is becoming increasingly popular in Assam. They are very effective at catching fish, but they can also be harmful to the environment if they are not used properly.
