Snapping Turtles
Snapping turtles grow quickly and have a high meat production rate, so It is also known as the "meat turtle", so this is a turtle that is humanly defined as edible. Humans will not give up delicious food and will not squander the opportunity to make profits, so the breeding of snapping turtles came into being. Here is an introduction The latest methods and techniques for breeding snapping turtles.
1. Turtle pond construction
Using water source is convenient and non-infectious , build a pool in a place that is easy to access but quiet. The appropriate shape is a cement plastered pool with an object-oriented rectangular arc corner or an earthen pool with the same shape but with a protective wall on the outside. The area of each pool is tens to hundreds of square meters; the depth of the pool is 1.2 meters to 1.5 meters. The water depth is 30cm~80cm; the bottom of the pool has a steep slope of 10°~16° from north to south, and the lowest point is equipped with a drainage pipe with an anti-escape mesh cover; the corners of the pool are all in a tricky arc shape, and are covered with anti-escape pressure plates. ; Build an anti-escape wall around the turtle pond. The wall is 1 meter high. Leave a door on one side of the wall. An anti-escape pressure plate ("T" shaped anti-escape wall) with eaves extending into the pool can also be added on the top of the wall. A hole with a diameter of 2 cm to 3 cm should be set every 0.6 meters on the top of the outer anti-escape wall. Leave several overflow holes on the highest water level of the outdoor cement pool wall. The newly built cement pool contains alkaline substances. You can use 10% glacial acetic acid to scrub the walls and bottom of the pool. Fill it with water and soak it for 1 to 2 days. After putting it aside, use the common method to eliminate the alkali once, and then clean it with clean water. , add new water. Before raising turtles, you need to use 15×10-6~20×10-6 bleaching powder or 1×10-6 "strong chlorine essence" to sterilize the entire pond. You can only raise turtles at 2 dawn.
In addition to the above general conditions, artificial discovery of the best growth temperature for a snapping turtle is a key method to enhance turtle breeding. Use smokeless steam boiler water (gas) heating at low temperature to keep the turtle pond water at about 30°C and the air temperature at about 31°C; you can also use temperature controllers and electric heating devices for constant temperature enhanced maintenance.
Two. Turtle breeding
Adopt high-density green breeding It is a new technique to achieve high efficiency, and it is also a new method for turtle breeding industry.The inevitable trend of development. The initial stocking density (about 200g/m2) is 24/m2~27/m2, and the weight should be about 5kg/m2. However, with the rapid growth of individual snapping turtles, attention should be paid to Instantly reduces density. When the balance specification reaches 350g/piece~400g/piece, it should be reduced to 20/square meter~22 pieces/square meter; when the balance specification reaches 500g/piece, it can be reduced to 15/square meter~17 pieces. /square meter; when 600g/bird, the stocking rate is 12/square meter~14/square meter; when 700g/bird, it should be 10/square meter~12/square meter; 800g/bird It is 8 pieces/square meter to 9 pieces/square meter.
3. Feeding
It is proposed to adopt SDG Snapping Turtle Expo Use green synergistic feed (protein content above 48%). When preparing, weigh the ingredients on site, add 5% to 10% of photosynthetic bacteria and about 45% of purified water to the total ingredients, and make long particles with a particle size of 2 mm to 3 mm. If conditions permit, floating extruded pellet feed will have better results.
The amount of common feed is 1.5%~2.5% of the total weight of the snapping turtle and 5%~10% of the fresh feed. Feeding is done three times a day, at 6:00 to 7:00, 12:00 to 13:00, and 17:00 to 18:00. Feed should be more even and even, and try to make a sound when the feed enters the water. Avoid gathering and throwing them in one place to form a pile of feed. The number of feed stations in each pool should be determined according to the size of the pool, generally 3 to 4 per square meter.
IV. Water quality arrangement
Based on high-density intensive turtle breeding Under such conditions, turtles eat more food and permeate more, and the water temperature is higher. Even if the feed fed is green feed, it will pollute the water quality faster, and more harmful substances will be easily produced in the water body, especially Ammonified nitrite and H2S are relatively harmful, but by pouring and submerging photosynthetic bacteria, water quality can be effectively improved and harmful substances reduced. When adding new pool water every time, use 10×10-6~15×10-6 photosynthetic bacteria at the same time; changing water is also an effective way to adjust the water quality. The water depth of 20 cm can be changed once a day, and the water depth of 30 cm can be changed every 2 days. once. Be careful not to change the water for many days, otherwise the water body will spread odor. Quicklime can be poured once every 7 to 10 days, with a concentration of 70×10-6, and it should be noted that it is applied alternately with photosynthetic bacteria and cannot be used at the same time.
5. Water temperature control
Scientific regulation of water temperature directly affects the growth rate and survival rate of adult turtle breeding. Snapping turtles grow at a rate of 18℃~20℃ for a long time. It is several times slower than the optimal growth water temperature of 30℃~31℃. Therefore, the water temperature of turtle breeding must be kept within 30℃~31℃. On the other hand, when the turtle pond is changing water or is exposed to the outside world and encounters severe weather such as heavy rain or sudden changes in temperature, immediate precautions should be taken and efforts should be made to avoid the water temperature changing by more than 2°C.
6. Disease Prevention
Snapping turtles are generally less likely to get sick. However, under high-density breeding conditions, it is easy to suffer from indigestion disorders. Sick turtles can be fed with bait containing multi-enzyme tablets (2 tablets per kilogram of turtle). For traumatic injuries, you can use iodine tincture cotton to disinfect the affected area, and it will heal in 2 to 4 days after applying anti-inflammatory and muscle-promoting ointment.
