摘要
对中华鳖的太湖群体和台湾群体，采用完全随机区组设计方法，在两个养鳖场，从稚鳖至成鳖阶段进行生长比较试验。两场温室和大棚试验的结果一致表明，太湖群体和台湾群体的生长规律有同有异。其共同点是，从稚鳖到体重２５０ｇ左右，日增重率逐步加快，个体间生长差异均较大；不同点是，在这一阶段，台湾鳖的日增重率较太湖鳖平均高出１０％左右，且个体间生长差异较小。
A completely randomized block designed experiment was conducted to study the growth performance of Taihu population and Taiwan population of soft shelled turtle at two turtle farms. The results indicated identically that, there are common and different points in growth performance between these two populations. The common points are, from juvenile to about 250 g adult, daily weight gain increases step by step, the variations of body weight among individuals are large. The different points are, in this stage, the daily weight gain of the Taiwan population is about 10% higher than that of the Taihu population , and the variations of body weight are rather slight.
