![]() ![]() When Tubifex solution was introduced at the central area of the plastic vessel with a fish, the fish suddenly started the Feeding-crawl and showed Gulp which was composed of Dig and Twist. It follows that the feeding behaviour of this fish is induced by some chemical stimuli. A gauze-covered vessel with Tubifex solution buried in the sand substrate released feeding behaviour in fish in its vicinity. Living Tubifex kept in a glass cell failed to elicit feeding behaviour in the fish. But they ignored an unsoaked piece of thread. The adult fish responded to a piece of thread soaked with filtered Tubifex homogenate ( Tubifex solution) and showed feeding behaviour. From observations the behaviour patterns were described. The feeding behaviour of a Japanese loach, Misgurnus anguillicaudatus was experimentally analyzed. ![]()
