宝应县科委及宝应县特种水产研究所近两年来探索了影响鳖卵孵化的因素,根据各种对比试验,初步认为,取卵时间(即卵产出后到从卵穴中取出进行孵化的间隔时间)早迟对孵化率没有影响;孵化期间,鳖卵动物极的方位(动物极朝上、朝下或水平方向)对胚胎发育没有多大影响,不管动物极的方位怎样,都能正常孵出稚鳖;孵化温度在试验所采用的25℃、28℃及33℃三种温度条件下,都能正常孵出稚鳖,但以在33℃下,胚胎
Baoying County Science and Technology Commission and Baoying County Institute of Special Fisheries in the past two years to explore the impact of turtle egg hatching factors, based on a variety of comparative tests, preliminary that the time to take eggs (that is, after the egg is taken out from the ovum hatching Interval time) has no effect on the hatching rate late; during the incubation period, the turtle egg polar orientation (animal up, down or horizontal) has little effect on embryonic development, no matter how the animal’s polar orientation, can be normal hatching Out of juvenile soft-shelled turtle; Incubation temperature in the test using 25 ℃, 28 ℃ and 33 ℃ under the conditions of three temperatures, hatching larvae can be normal, but at 33 ℃, embryos
