Abstract:

Abstract  Benthic macrofauna and nektons used to be abundant on the tidal flats and mangrove exposed tidal waters in the mangrove zone of Yingluo Bay,Guangxi.However,their amounts decreased by about 60% and 80% respectively in the past four years.This was directly caused by human uncontrolled collection of the species that have increasing commercial values at the markets.The methods of collection included digging macrobenthos on tidal flats,netting,bombing and poisoning fish in mangrove exposed tidal waters and water ways.The mesh size of the nets was usually as small as 0.25 cm.These traditional fishing activities extremely decreased the flow of matter and energy among the mangrove food web,fragmented animal habitats,and endangered the survival of populations.The mangrove fishery was whatever vital for the local residents,thus entire close of the mangrove tidal flat for conservation is impossible at present. So,a technique of turn flat closed nursery was suggested for the management of the mangrove tidal flats in Yingluo mangrove area. Meanwhile, enhance of public education was also recommended.
