为研究河蟹的生长特性,本文通过对大通湖(12万亩大水面),千亩湖(多个25亩池塘)河蟹的雌雄胸甲长,胸甲宽,胸甲厚与体重及河蟹可食部分研究,结果表明:胸甲宽与体重存在很好的线性关系,公蟹的胸甲宽与体重线性关系为y=0.1336x+46.693,母蟹的胸甲宽与体重线性关系为y=0.1635x+45.019。而通过对大水面与池塘河蟹生长(主要是体重)研究,发现大水面养的河蟹体重要普遍高于池塘。通过对河

　　to study the water crabs crabs and pond growth characteristics of difference, the author through to the datong lake (120000 mu water surface), one thousand acres of lake crabs (25 mu pond) study, in order to find out the growth of their difference, and the growth characteristic of crabs, such as crabs and male chest armor is long, wide chest armor, the breastplate thickness and weight if there is a linear relationship, the answer is yes and chest width and weight is a good linear relationship.And through to the large surface to the growth o...
