Amplified fragment length polymorphism （AFLP） analysis was used to evaluate the genetic diversity of four wild geographical populations of Japanese flounder （Paralichthys olivaceus）. A total of 775 loci （58.32% of which was polymorphic） in the range between 100 and 1 300 base pairs were detected from 110 individuals using seven primer combinations. The percentage of polymorphic loci detected by single primer combination for each population was calculated, ranging from 19.59% to 53.33%. Genetic similarities within and among the populations were calculated from the binary matrices of presence - absence. Phylogenetic tree of four populations was constructed by using the UPGMA method using PHYLIP Version 3.5. According to intrapopulation genetic similarities, CW population displayed the highest genetic diversity value and KY population had the lowest genetic diversity value. The distance between CW and CF populations was the farthest, which was possibly resulted from the farthest distance of Weihai of Shandong and Fujian of China compared with the geographical distance between other locations of populations. The subpopulation differentiation value （G.,） is 0. 356 5, showing a certain extent of differentiation among the four geographical populations. AFLP technology was confirmed to be an effective tool to assess within- and among-population genetic diversity of Japanese flounder. The present survey provided significant insights for research in the Japanese flounder breeding program.

Trumpet shell, Charonia sauliae, is an endangered and valuable species, but its artificial propagation protocol has not been successfully established. To estimate the possibility of cryopreservation for larvae of C. sauliae, which is a potential preparation for its artificial reproduction and further research, in this study a protocoi for the cryopreservation of veliger larvae of trumpet shell was optimized. Through a two-step cryopreservation procedure, four kinds of cryoprotectants （ethylene glycol, 1, 2-propanediol, dimethyl sulfoxide and glycerol） were employed at three concentrations （1.0, 1.5 and 2.0molL^-1） respectively and survival rates of larvae were determined after a storage of lh. The larvae frozen with these four cryoprotectants after 1 h storage were cultured, and then survival rates were determined at 24, 72 and 120 h after thawing. Dimethyl sulfoxide at a concentration of 1.5 molL^-1 showed the best protective effect in all experiments （p〈0.05）. And survival rates of larvae frozen with dimethyl sulfoxide were determined after 1, 7 and 15 d of storage. The survival rates of larvae frozen with 1.5 molL^-1 dimethyl sulfoxide after 1 h, 1 d, 7 d and 15 d of storage were 80.77% ±7.51%, 80.34%±11.28%, 83.10%±9.14% and 77.23%±6.22% respectively. No significant differences in survival rates of larvae frozen with dimethyl sulfoxide were observed after various storage periods （p〉0.05）.

This paper investigates the double randomness matching mechanism between electric vehicle（EV） charging and wind power in a distribution network. The Markov Decision Process is employed to model the uncertainties of both EV and wind power. The optimized dispatching models and strategies for EV charging under multi-time scale are developed to achieve the objective *** goal of this function is to maximize matching degree between EV charging and wind power as well as minimize the power losses fully taking the physical constraints of distribution network into account. This actualizes dynamic control of EV charging. The simulation results on IEEE 5 node system and IEEE 30 node system demonstrate that the optimal dispatching method can reduce the network power losses and improve the matching degree between the EV charging and wind power.
