Ego-ryo, a unique way of catching ayu fry fish on Amori-river system, Kagoshima prefecture, was studied on the structure of fishing devices used, the actual operation, and the catches. The fish were caught from the 1 st of March to the end of April at the nine fishing grounds established between 5.2-9.9km upstream of the river mouth. Each fishing ground was constructed from a flat floor (150m long, 20m wide), an embankment hemmed on each side, and a wooden weir of the upper end and fence nets with traps of the lower end surrounded. Once fish schools came in the fishing grounds, the weir was shut to keep out the inflow of water causing drainage of water in the ground. The drainage stimulated the fish to rush into the trap. This draining technique which leads them into the trap has not been known in any other ayu fry fishery in Japan. The Ego-ryo fishery might be settled in the way that ayu fly are caught in the lower river and released in the upper river, where they will find it difficult to ascend.
