Status,Problems and Optimized Management of Spawning, Feeding,Overwintering Grounds and Migration Route of Marine Fishery Resources in Bohai Sea and Yellow Sea
For most marine organisms,spawning,feeding and overwintering grounds and migration route are important links and habitats in their life cycle for maintaining the population structure and size.The spawning,feeding,overwintering grounds,and migration route in the Bohai Sea and Yellow Sea,important fishery habitats,are facing functional decline and resource depletion in recent years due to extensive reclamation,marine environmental pollution,overfishing,economic development and climate change.In this paper,based on the literaturesavaillable,we focused on the spawning,feeding and overwintering grounds and migration route in Bohai Sea and Yellow Sea and summarized their status, changes,problems as well as the causes of these problems.For sustainable management,we suggested to control the reclamation in the perspective of ecological function protection,control pollution by ecocompensation, increase freshwater in Yellow River Delta in the spawning season and ecologically restoring the key areas.
