Abstract: The relationship between the amount of Eriocheir sinensis'larvae and various factors is analysed in this paper.It is observed that in recent years,the amount of Eriocheir sinensis'larvae is obviously decreased.Besides the influence of water conservancy project,the changes of Changjiang estuary and the pollution of water-body,over-catching of crab's parents is a very important factor.It is suggested that not only the ecological environment of Changjiang estuary,but also the spawning site and spawning parents of Eriocheir sinensis should be protected.
