How to make female eggs more spawning is directly related to the economic benefits of raising turtles. The author has summarized the shallow and shallow experience of raising the female's eggs laid in the past 20 years as follows:

1. Quiet environment The location of the hatching pond should be arranged in a quiet, sunny, and sheltered place, especially in the vicinity of sudden loud noise environment, such as the shooting range, blasting stones, and the sudden loud noise of the airport. Eggs have an effect. In the mating season of turtles, people and animals must be prevented from disturbing the pool. In the mating and breeding season, feed as much as possible on the afternoon of the feed every day, and it is advisable to catch turtles before coopulation and spawning. Because most turtles begin mating and spawning in the evening. Only a few turtles, such as the colorful turtle, spawn during the day, and they should also prevent excessive interference during this time.

2. Adjust the water quality turtles like to live in light green or tea green water, the general transparency of 10 to 30 cm. This reduces external interference and makes the turtle safe in the water. And this kind of water plankton is also the most, and it is good for turtles to take food. If necessary, you can put some green lindens and water lilies in the pool during the summer, which can both shade and prevent high temperatures and can adjust the water quality. Some turtles also like to eat green plants, and eating turtles on the surface of water can increase vitamin intake. To maintain the water quality pH 6.6 ~ 8.1 is appropriate, to prevent the strong acid and alkaline substances and toxic pollution, pH value, such as when the bias is less than 6.6 when applied to adjust the fresh lime slurry. Under the premise of keeping the water quality stable, try to change the water as little as possible, if necessary, slowly switch in and out to prevent over stimulation to disturb the turtle.

3. When the stocking density is appropriate, the general water depth is 1 meter, 3 turtles are stocked per square meter, 6 stocks per square meter are stored at a depth of 2 meters, and 2 stockings per square meter are appropriate when the water depth is less than 0.5 meters. When the water is too shallow, the stocking density should be reduced so that it has a relatively quiet activity space that interferes less with each other.

4. The ratio of male to female is normal. The ratio of male to female of common turtle species is 1:2. If it is more than 1:3, the fertilization rate of female turtle is obviously decreased. At 1:1, male is too much and it is also easy to interfere with female turtle. spawning. It is also necessary to make appropriate adjustments depending on the species of the turtle. The ferocious turtle species such as the olecranon and snapping turtle have a smaller percentage of males, while the yellow-throated turtle, turtle, and gold-headed turtle have docile temperate turtle species. More, it will help increase the proportion of fertilized eggs and increase the hatching rate.

5. The spawning ground of the spawning ground shall be mixed with half of the sediment, and the surface shall be leveled. The above ground shall be protected against heavy rain. During the spawning season, the eggs are re-flattened after picking eggs each day. The first is to facilitate the subsequent spawning turtles to dig spawning pits, and the second is to facilitate manual egg retrieval. In dry weather, water can be poured onto the sand to prevent the lack of water and make the turtle eggs lose water after birth, affecting the hatching rate. Having a good spawning site can prevent the eggs from being produced in the pool water immediately after the female eager to spawn and cannot find a comfortable spawning location.

6. The nutrition content of forage nutrition feed should not be lower than 39% to 41%, calcium content is not less than 1.2%, compound vitamin is not less than 1.1%, lysine is not less than 1%, mineral salt is not less than At 1%. If there is no special feed, it can be replaced by quail feed and the effect is equally good. Sporadic household culture, as much as possible to feed more small fish, shrimp, shellfish, clams, cocoon, insects and animal waste, such as pigs, cattle, sheep, chicken, viscera, and appropriate mix of cornmeal, soybean cake, peanut cake and the like And feeding.

7. Fixed-point quantitative time-feeding for fixed-point feeding can reduce feed wastage and reduce the turtle's search for physical energy consumption. Timing feeding is beneficial to the regulation of digestion and absorption function of the turtle body, is conducive to the release of estrogen, accelerates the development of follicles, advances the development and produces early eggs. And prolong the spawning period. The ration is based on the body weight of the turtle feeding no less than 3% (dry material) per day. However, the corresponding decrease in spring and autumn. The amount of feed that is normally put into turtle ponds is within 2 hours.

8. Increase the light to fill the turtle can increase appetite, is conducive to nutritional digestion and absorption, increase the amount of eggs laid. From the beginning of summer to the beginning of the fall, you can hang a sun lamp on the turtle pond and turn on the light 2 hours before dawn in the morning. You can also use light to lure the insects and moths to feed freely.

9. Regulate the water level Steady water temperature The temperature of the turtle is kept between 3°C and 12°C during the winter, allowing the turtle to hibernate deeply and avoid long-term water temperatures in the range of 13°C to 14°C, which causes the turtle to hibernate without deeper resulting in excessive consumption of the turtle body energy. Affect the number of eggs laid in the following year. Before and after the winter, when the weather is fine, when the weather is fine, the depth of the pool water can be appropriately reduced during the day, and sunlight can be used to warm the pool water; night or rainy weather can deepen the pool water insulation, which is favorable for turtles to ingest more food and produce more eggs.
