Advances in studies on germplasm in Chinese mitten crab, Erocheir sinensis

The auhor summarizes the major results in study on genetic characters of morphology, culture performance, cytogenetics, enzymatic genetics and molecular genetics in Chinese mitten crab (Eriocheir sinensis), including the genetic differences in morphology, cytogenetics, enzymatic genetics and molecular genetics levels. In terms of morphology, the discrimination function to differentiate the morphological traits of different populations of crab is established. In biochemical genetics and molecular genetics aspect, the genetic markers from enzymatic and RAPD profiles are discovered in distinguishing Eriocheir sinensis and Eriocheir japonicus, etc, and the other populations of Eriocheir sinensis. In the culture performance aspect, the variations and characters of growth performances, such as molt, growth, gonad development and spawning migration of different populations are evaluated. A set of discrimination method and technique is established to distinguish the different populations of mitten crab as well as other crabs. Meanwhile, the measures to protect the germplasm resourcs of Chinese mitten crab are put forward.
