Sand mining can affect the marine habitat adversely by removing the sand and its plume, which raises mortality of fisheries and causes damages to ecosystem. Until now, there is no report on the effects of sand mining on fishery based on a long-term monitoring in the Pearl River estuary, except for a study that analyzed the changes caused by navigational channel dredging based on investigation of fishery resources, which are similar to the changes caused by sand mining. According to the study (Wang and Zhang, 2001), the environmental protection measures had been taken, but the number of fishery resources changed obviously before and during the dredging period (Table 4).
