An experiment was conducted on fish culture in small-sized net cage with the size of 1 m2 × 1. 5 m, 4 m2 × 2 m, 9 m2 × 2 m. The results showed:the small size of 4 m2 × 2 m is suitable for fish culture;don' t shut out the sunlight for farming the fish living in the water surface,but shut out the sunlight for farming the fish living in the water bottom; the small net cage is set up in the medium and POor nutritious reservoir shallows on the leeward in the rich nutritious reservoir far from the leeward; feeding diets ought to spread with hand many times. The profit of fish culture with small net cage raised 40% and the output price increased 130% more than with conventional net cage.
