Abstract
Gill net, cast net, and shrimp pot have been used to survey the catch in the artificial reef area of Zhongshan city in high flow period and in dry season separately. The survey results in high flow period showed that the experimental float artificial reef had an obvious effect on attracting fish and protecting juvenile fish and prawns in the experimental year, and the survey results in dry season even showed this effect of the first phase of artificial reefs rather obviously, which provided safe havens and feeding niches for living things and became a seed storehouse of fish stock around the sea area. Artificial reefs of large area had a better effect on protecting fish stock and marine ecological habitats.
