In any aquaculture industry, to obtain high yields and excellent offspring, we must pay attention to the selection of this species. Due to the high economic value of turtles, driven by the market economy, the turtle industry has rapidly developed in recent years, and most of the provinces and cities in China have already started artificial breeding. However, the source of the seedlings restricts the development of the turtle industry to a certain extent. The solution is to rapidly multiply resources and reproduce artificially. The choice of turtle species is crucial to the success or failure of artificial turtles.
First, choose the general principle of turtle species
The turtles used for breeding are called turtles. The choices of various turtles vary, but the basic principles are the same. General requirements of gonads begin to mature, strong physique, bright body color, action sensitive, bright eyes, large individuals, no disability, no deformity, intact tail and limbs without incomplete, epidermal, dorsal and abdominal no damage, no ulceration. Method of inspection: When the turtle is placed on the ground and its head is touched with a thin rod, its head and limbs will be quickly retracted into the shell; if it is placed upside down, it will quickly extend its head and turn it quickly and forcefully. Come; the four limbs can support the body when crawling. Wild turtles are generally used as interracial turtles, but the source of wild turtle species is not easy to understand, and fishing injuries and internal injuries are serious and the survival rate is extremely low. The inspection method for wild turtles is to place the turtle on the ground. The turtle will extend its head and neck. If the surface is filled with blood, the head and neck become thicker, it will not stretch when extended, nor will it be able to flexibly rotate. When touching, the head and neck cannot be completely Inward contraction indicates that there is a fishing injury. If the injury is in the belly, the neck can be retracted, but the back body is often lifted upwards. If you have internal injuries, you do not like to go into the water. If you hold your fingers on both hind legs, they will automatically hang down. If there is a serious hind leg injury, you can try to raise them. If both legs are sagging, the internal injuries are serious and not easy to survive. They should be eliminated.
