8.2.3.3 Trammel Net

This net is a modified form of gill net, comprising three layers of gill nets. The inner or middle net possesses a small mesh but larger depth. It is held between 2 outer nets with a large mesh but smaller depth. Because of this peculiar set up of three nets, fishes of various sizes are generally caught by this modified form of gill net. It has been observed that small fishes are gilled in the fine mesh working of inner nets, but larger fishes, while swimming, strike against the outer nets. Consequently they get entangled in the pockets formed by the inner net as extrusion. In large tanks and reservoirs of many places, this net is operational to catch fishes of various sizes.
