Analysis On Growth Performance And Breeding Efficiency Of Eriocheir Sinensis Ponds In Xinghua Area

In this paper, the Jiangsu area of the Chinese crab pond culture as the research object, based on the Jiangsu province of Xinghua and the surrounding areas, With a single pond as the research object, choose to use the same brand feed in the aquaculture pond, In the same farming year(2014), According to their time stocking mitten crab, fry stocking size, fingerling stocking density data, from the harvest of crab commercial average specification, the number of male and female crab and the proportion of weight,weight gain on statistics analysis on the economic efficiency of pond aquaculture of Eriocheir sinensis on growth performance and economic benefit.To compare the growth rate and the proportion of male and female crabs in the pond culture of different kinds of Chinese cashmere crab, and to explore the better pond model and the proportion of the different sizes. Our results show that there is a direct relationship with the crab breeding ponds economic benefit model, individual specifications,the proportion of male and female.1. Even smaller size aquaculture ponds yield achieved good results can not be obtained best value for money, Therefore crab specification is one of the main factors affecting the breeding efficiency. The larger size crab, good prices, high breeding value for money, such as seven and eight of the pond is the best of nine pond. Both ponds breeding efficiency is the best. High proportion of male crab, can get big crab Specifications and high economic benefit, In nine pond is proportion of individual female crabs were the highest. In Xinghua area, the existing pattern of the crab is more reasonable, which can not only meet the requirements of the growth performance, but also can obtain good economic benefits.. The main breeding crab, with shrimp and filter feeders fish can obtain good economic benefits, the number density of Eriocheir sinensis in 1200~1500/667m2, specification 5~6gtail,shrimp 3~5kg/667m2(about 3000 tail / 500g), filter feeders fish 20~30/667m2. 10~15 mandarin fish(3~5cm in body length), this model can obtain the best economic benefits, such as the seven pond.
