Preliminary study on the breeding performance for wild Yangtze River brood stocks of Chinese mitten crab
摘要
Abstract
In November,2011,1 388 wild Yangtze River wild brood stocks of Chinese mitten crabs were chosen from Wuwei county,Anhui province for ecological breeding in natural sea water in Rudong county,Jiangsu province,of which 350 were male with a total weight of 80.05 kg,and 1 038 were female with a total weight of 194.05 kg.Comparing breeding experiment was conducted in two ponds of 2.5 mu in size,with the water condition of 19‰-26‰ for salinity,and 8.28-8.90 for pH.The breeding characteristic differences between the wild and common brood stocks were studied.The results indicated that the weights of body and ovary for the wild brood stock were higher than those of the common one,and the difference was extremely significant.The differences for the mature index and relative fecundity between the wild and common brood stocks were not significant.The spawning rate of the wild brood stock (52.85％) was higher than that of the common brood stock (30.91％).The development speed was faster and the size was bigger for the wild larvae than that of the common larvae.The total volume of the wild megalopa was 6.5 kg with a size of 125.3 tails per gram,and 23 kg for the common brood stock with a size of 156.5 tails per gram.关键词
