1. Observations were made on the behavior of the fish that gather around the floating seaweeds. Their feeding habits were also investigated from the stomach contents analyses.2. By observing swimming tendencies in their natural environment three types are distinguishable, i. e. fish always keep contact with the floating seaweed; fish swimming freely around the floating seaweed and the fish seemingly afloat around the floating seaweed.3. The food compositions are complicated in the fish that keep contact with the floating seaweeds and they become more simple as the fish begin to swim further from the floating seaweeds. Many of them are dependent on the floating seaweed to a greater or lesser extent for both food and shelter.
