The Snapping Turtle is one of the world's leading breeds of turtles and is best known for its highest meat yield (85%-89%). The meat is delicate and crisp, and its nutritional value is far more than that of pigs, cattle, and lamb. It is full of treasures, meat, liver, gallbladder, blood, bones have a variety of medicinal health effects, flexible and smooth skin can make valuable leather handbags, bags and so on. Therefore, the active development of snapping turtle breeding will be very promising. At present, the price per kilogram of snapping turtles ranges from 800 yuan to 1,000 yuan, and no goods are available. In order to meet people's preference for the consumption trend of green food, the new technology for green breeding of snapping turtles is introduced as follows:
I. Turtle Pool Construction Select a place where the water source is convenient, pollution-free, and the transportation is convenient but quiet. The shape of the tank is the shape of a rectangular concrete arc-shaped corner of the east-west direction, or an earthen pond of the same shape but built to prevent escape. The area of ​​each pool is several tens of square meters to several hundred square meters; the depth of the pool is 1.2 meters to 1.5 meters. The water depth is 30 cm to 80 cm; the bottom of the pool has a slope of 10 to 16 from north to south; the lowest part is equipped with a drain pipe with an escape protection cover; the pool corners are rounded and arc-shaped; The outer perimeter is built to escape the wall. The wall is 1 meter high. The door is left on the side of the wall. The top of the wall can also be equipped with an anti-ripple plate (“Tâ€-shaped escape wall) that can escape into the pool. The top of the outer wall of the escape prevention wall should have a socket with a diameter of 2 cm to 3 cm every 0.6 meters. Several overflow holes are left on the highest water level of the outdoor cement concrete wall. The newly built concrete pool has alkaline substances, which can be cleaned with 10% glacial acetic acid, and soaked for 1 day to 2 days after filling with water. After the release, the alkali should be removed once with the same method. Then rinse with clean water. Into the new water. Before turtle breeding, it is necessary to use 1510-6 ~ 2010-6 bleach or 110-6 "strong chlorine" to disinfect the whole pool. After 2 days, turtles can be stocked.
In order to help reduce heatstroke, increase shelter, and purify water quality, Chichizhong should plant water peanuts, water hyacinths and other plants. Its area does not exceed 1/4 to 1/3 of the total area of ​​the pond; scaffolding can also be used to make use of climbing vines. The plants come shaded to form an artificial bionic green environment.
In addition to the above-mentioned general conditions, artificially creating an optimal temperature for the growth of a snapping turtle is an important measure to strengthen the conservation of turtles. At a low temperature, the smokeless boiler water (gas) is warmed to maintain the turtle pool water at about 30°C, and the air temperature is about 31°C; it is also possible to use a temperature automatic controller and an electric heating device to achieve constant-temperature enhanced feeding.
Second, the use of high-density green breeding turtle species is a new technology to obtain high efficiency, but also the inevitable trend of turtle industry development. The initial stocking density (200 g/approx.) is 24/m2 to 27/m2, and should be about 5 kg/m2 by weight, but with the rapid growth of snapping turtle individuals, care should be taken to reduce them in time. density. When the average specification is 350 g/only -400 g/only, it should be reduced to 20/m2 to 22/m2; when the average specification is 500 g/only, 15/m2 to 17 can be used. /2 square meter stocking; 600 g / only, according to 12 / square meter to 14 / square meter stocking; 700 g / only should be 10 / square meter to 12 / square meter; 800 g / only 8 per square meter to 9 per square meter.
Third, feed feeding recommended SDG snapping turtle special green feed (protein content of more than 48%). Weigh the ingredients on site and add photosynthetic bacteria with a total weight of 5% to 10% of photosynthetic bacteria and about 45% of clean water to make long particles with a particle size of 2 mm to 3 mm. If conditions permit, floating granules made of feed, the better.
The fed amount of compound feed is 1.5% to 2.5% of the total weight of snapping turtles and 5% to 10% of fresh feed. Feeding 3 times a day, respectively, at 6 to 7 o'clock, 12 o'clock to 13 o'clock, 17 o'clock to 18 o'clock. Feed more and evenly, and make noise as much as possible when feeding into the water. Do not concentrate on one place, resulting in feed piles. The number of feedstuffs per pond should be determined according to the size of the pool, generally 3 to 4 per square meter.
Fourth, water quality adjustment In view of high-density intensification of turtle conditions, the turtle's food intake and excretion are more, and the water temperature is higher, even if the feed is green feed, the water pollution rate is also faster The water body is prone to produce more harmful substances, especially ammoniated nitrite and H2S, and by splashing and applying photosynthetic bacteria, we can effectively improve water quality and reduce harmful substances. Each time a new pool of water is added, 1010-6 to 1510-6 photosynthetic bacteria are applied at the same time; changing water is also an effective method for regulating water quality. A water depth of about 20 cm can be changed once a day, and a water depth of 30 cm can be changed every 2 days. Do not change the water for many days, do not allow the water to emit odors. Every 7 days to 10 days, one quick lime can be splashed with the concentration of 7010-6, and pay attention to cross-administration with photosynthetic bacteria.
Fifth, the scientific regulation and control of the water temperature control water temperature directly affects the growth and survival rate of adult turtles. The long-term growth of snapping turtles at 18 °C to 20 °C is several times slower than the optimum growth temperature of 30 °C to 31 °C. Therefore, be sure to maintain the turtle's water temperature within 30 °C ~ 31 °C. On the other hand, turtle ponds that are changing water or being exposed to the outside world should be protected in time when they encounter severe weather such as heavy rain or sudden changes in temperature, and they should try to avoid changes in water temperature greater than 2°C.
Six, disease prevention Snapping turtles are generally less sick, but in high-density farming conditions susceptible to indigestion, can be fed to the diseased turtle containing multi-enzyme tablets bait (2 tablets per kg of turtle medication). Traumatic disease can be used to disinfect the affected area with iodine cotton wool, coated with anti-inflammatory muscle cream after 2 days to 4 days Jiyu.
