幼鳖个体小,体质娇嫩瘦弱,特别是8～9月产卵孵出的幼鳖,在越冬期间常发生大量死亡。要提高幼鳖越冬成活率,应抓好以下几个技术环节。 一、加强幼鳖越冬前的饲养 1.实行人工孵化,提早幼鳖培养期。鳖卵在自然条件下孵化,孵出幼鳖须经60～80天。8～9月亲鳖产的卵,孵化成幼鳖就进入越冬期,此时的幼鳖生长期短,体内营养物质贮备不足,体质瘦弱,难以渡过漫长的冬眠期。采用人工控温控湿孵化,保持鳖卵孵化温度在28℃～32℃、湿度80％～90％,能加速鳖卵胚胎发育,缩短孵化时间15～20天,有利于提早对幼鳖进行饲养,延长幼
Juvenile soft-shelled turtle, small delicate physique, especially from August to September laying eggs hatched young turtle, often occur during the winter a large number of deaths. To raise the survival rate of juvenile turtle overwintering, should grasp the following aspects of technology. First, to strengthen the feeding of juvenile turtle before winter 1. The implementation of artificial hatching, early young turtle training period. Soft-shelled turtle eggs hatch in natural conditions, hatching young turtle to be 60 to 80 days. 8 to 9 months of soft-shelled turtle eggs, hatching into juvenile soft-shelled turtle into the overwintering period, when the young turtle growth period is short, the body lack of nutrients, physical thin, it is difficult to survive the long period of hibernation. Controlled by artificial temperature and humidity incubation, keeping turtle egg hatching temperature 28 ℃ ~ 32 ℃, humidity 80% ~ 90%, can accelerate the embryonic development of turtle eggs, shorten the incubation time of 15 to 20 days, is conducive to raising young turtle early , Extend the child
