| Abstract: | Growth of two years old of Cuora flavomarginata(Gray) were studied by natural temperature culture(14.7~33.3 ℃) and stages control temperature culture(20.3~33.3 ℃) in stages,The results showed that,the average body weight gain of turtle in natural temperature calture was after 180 days′ experiment,54.27 g,and the relative growth rate was 115.89%,the absolute growth rate was 0.30;for turtle cultured in controlled temperature,theirs average body weight gain was 72.88 g,the relative growth rate was 1157.95%,the absolute growth rate was 0.41.The average body weight in control temperature culture was 1.34 times higher than that in natural temperature culture.The growth rate of control temperature culture was faster than the growth of natural temperature culture.Under the natural temperature condition,young turtle grew slower in May,weight showed negative growth in October,the faster growth rate occurred from June to September.Under the control temperature condition,young turtle grew fast in May but was slow in October,the faster growth rate occurred from May to September,and growth period was extend about 30 days.Under the natural temperature condition,the growth equation of body weight and daily age was W=37.3758+0.6610T-0.0015T2,r=0.9768,r>r0.01(P<0.001);Under the control temperature condition,the growth equation of body weight and daily age was W=39.3271+0.68099T-0.0012XT2,r=0.9923,r>r0.01(P<0.001).In both culture conditions,the body weight,carapace length,plastron length and carapace high were correlated positively with daily age,there were significantly positive-relationships between body weight and carapace length,body weight and plastron length,body weight and carapace high also. |
