Abstract or Summary
  • The coastal ecosystem of the Pearl River Estuary (PRE) has been overfished and received a high level of combined pollution in the past decades. The fisheries stock assessments have shown a declining population and have led to a number of management measures, including fishing moratorium. This study evaluated the effect of the fishing moratorium on the sustainability of PRE fisheries through an ecosystem approach. Then, a series of 100 years dynamics simulations were examined in light of five scenarios on the basis of the 1998 Ecopath model to explore better strategies on the fishing moratorium. S0: the present fishing moratorium continuation, S1: No fishing moratorium executed, S2: extending the duration of the moratorium (i.e., 1 June to 1 September), S3: banning all fishing operations in the moratorium season, S4: No fishing moratorium executed but reducing the fishing effort of all fishing gears by 50%. The results show that the fishing moratorium did benefit the ecosystem protection. Comparative analysis among different scenarios indicates that the largest increase (28.0%) in the fish stocks could be obtained in S4. Moreover, it incurred an increase (43%) in total landings. There seemed to be no differences between S0 and S3.
