中华鳖(俗称甲鱼)是变温动物,当外界环境水温下降到15℃以下时,就潜入泥沙中开始冬眠。一年内有半年时间冬眠,冬眠后的甲鱼体重将减少10～15%。甲鱼实际摄食生长期非常短,仅有4个月左右。在常温饲养条件下,要达到商品出售价(500g/只),通常要经过4～5年。因此,在自然条件下,进行人工养殖甲鱼经济上很不合算。故如何使甲鱼缩短养殖周期,达到快速生长,提高经济效益,将是我们研究的课题。
Soft-shelled turtle (commonly known as soft-shelled turtle) is a warm-blooded animal, when the external environment temperature dropped below 15 ℃, it sneaked into the sand to start hibernation. Hibernation within six months of a year, after hibernation turtle body weight will be reduced by 10 to 15%. The actual feeding period of soft-shelled turtles is very short, only about 4 months. Under normal temperature conditions, to reach the sale price (500g / only), usually after 4 to 5 years. Therefore, artificial breeding of soft-shelled turtles is not economically justified under natural conditions. So how to shorten the turtle breeding cycle, to achieve rapid growth and improve economic efficiency, will be our research topic.
