对黄喉拟水龟(Mauremys mutica Cantor)一龄龟生长的研究表明:在自然温度、人工饲以鱼肉的条件下,黄喉拟水龟生长418 d,体重由9.8 g增加到100.1 g,平均日增重0.22 g,成活率为93.4%。体重、背甲长、背甲宽与日龄呈正相关,背甲长与宽呈正相关,背甲长、背甲宽与体重同样呈正相关。黄喉拟水龟一龄龟在50 g以下时生长缓慢,50 g以上时生长速度明显加快。在相同环境条件下,个体间的生长速度差异较大。一龄龟最大个体可为同龄最小个体的4倍。
對黃喉擬水龜(Mauremys mutica Cantor)一齡龜生長的研究錶明:在自然溫度、人工飼以魚肉的條件下,黃喉擬水龜生長418 d,體重由9.8 g增加到100.1 g,平均日增重0.22 g,成活率為93.4%。體重、揹甲長、揹甲寬與日齡呈正相關,揹甲長與寬呈正相關,揹甲長、揹甲寬與體重同樣呈正相關。黃喉擬水龜一齡龜在50 g以下時生長緩慢,50 g以上時生長速度明顯加快。在相同環境條件下,箇體間的生長速度差異較大。一齡龜最大箇體可為同齡最小箇體的4倍。

Growth of one-year-old Asian yellow pond turtle (Mauremys mutica Cantor) was studied from August l998 to October l999.When the turtles grew for 418 days in natural temperature under artificial feeding condition in Guangzhou, their average body weight increased from 9.8 g to l00.1 g, the average body weight increased 0.22 g per day, the survival rate was 93.4%. The body weight, carapace length and carapace width were directly proportional to daily age. When the body weight of turtle was under 50 g, the turtle grew slowly. While its weight was over 50 g, it grews fast. Under the same feeding condition and for the same batch of turtles, the individual growth rate was different each other significantly. The maximal body weight of one-year-old turtle could be 4 times larger than minimal body weight.
