【摘要】 为了了解养殖环境对河蟹生长特性的影响,对大通湖水域中湖泊和池塘养殖的河蟹体长、体重及头胸甲关系进行了研究。结果表明:2种环境下雌雄河蟹头胸甲长、宽、厚与体重均存在密切的线性相关性,且湖泊河蟹其相关性(0.821 4~0.903 3)比池塘河蟹(0.898 8~0.945 7)要稍高;同环境下,母蟹头胸甲宽、厚与体重相关性均比公蟹高,公蟹头胸甲长与体重相关性比同环境下母蟹高。因此,河蟹部分生长特性与养殖环境、性别与其环境相互作用明显。更多还原

【Abstract】 In order to study the effect of breeding environment on the growth characteristic of the crab, the correlation between body weight and carapace of the crab in the large water and Qianmu Lake(25 mu pond)of the Datong Lake is studied. The results showed that the relationship between length, width, thickness of carapace and body weight in both male and female crab have closely linear correlation under the above two kind of environment, and the correlation of crab in lake(0.821 4~0.903 3) is higher than that in pond(0.898 8~0.945 7); Under the same environment, the correlation between width of carapace, as well as thickness of carapace in female crab and body weight is higher than male crab, while the correlation between length of carapace and body weight in male crab is higher than female crab. Based on these results, it can be confirmed that the interactions of growth characteristics and breeding environment, gender and its environment are obvious in the crab.更多还原
