The main reasons caused theses problems are as follows: beyond marine carrying capacity and environment capability by predatory and extensive manners, over-exploitation of bioresources resulted in the disturbance of marine ecosystem and the obstruction of matter and energy circulation.

The population explosion as well as the trend of population towards coast inflicted tremendous pressure on marine resources and environment. The weakness of marine laws system and the infirmness of macroscopical control by government policies relulted in unreasonable utilization, inefficient management, and insufficient protection of marine bioresources.
