With the improvement of people's living standards, the cultured turtles can no longer meet the needs of people, and the wild turtles have become the new favorite. To this end, many turtle farmers meet the needs of consumers through the turtle-like wild-breeding technology. Today, Xiaonong.com will tell you about the wild-breeding technology of the turtle pond.
First, materials and methods
Pond selection : a square pond connected by four “ten†characters with an area of ​​625 m2. The ecological environment around the pond is good, the transportation is convenient, the bottom of the pond is flat, the thickness of the silt at the bottom of the pond is 20~25 cm, the average depth of the pond is 1.6 meters, the light is sufficient, and there are perfect drainage facilities.
Water quality : direct water from the canal, continuous water flow, abundant water, fresh water and no pollution, dissolved oxygen up to 5 mg / liter, pH value of 7.0 ~ 8.5, water body transparency of 40 ~ 45 cm It fully meets the requirements of the “Water Quality Standard for Freshwater Aquaculture without Pollutionâ€.
Farming pond facilities : The pools connected by the four ponds are vertical and smooth, with masonry plastering, 15 cm in the direction of the upper side of the pool; the unconnected pool is sloped, the slope ratio is 3:1, and there is a poolside A rectangular open space of about 1.5 meters wide, with a fine sand of about 30 centimeters thick, for drying, rest and spawning, and an anti-evasion wall with a 50 cm high cement plastering surface. The inner walls are smooth. The top of the wall is 15 cm inward to prevent smashing and invading.
In order to solve the problem of eating squid, a bait table is built in the pool with 40 cm × 200 cm of wood, which is 10-15 cm above the water surface, and the inclined end extends 15 to 20 cm below the surface of the water, which can also serve as a drying platform and activity. Rest place.
Scientific stocking : Pond disinfection: After the sale of squid in winter, drain the pool water to clear the pond, and in the first half of the stocking period, each pool is sprinkled with 120 kg of lime (130 kg/mu). The pool is thoroughly sprinkled with scorpion after 1 day. Turn the bottom of the pool 1 time to kill the pathogens hidden in the sediment. After that, the new water is injected into the culture pond to a depth of 50 cm, and the dead fish and other debris are completely removed by hand to prevent the water from being clean.
Cultivation of natural bait : 70 kg/mu of organic fertilizer fermented in ponds (or 75 kg/mu of decomposed chicken manure) is used to cultivate plankton in the water for feeding after entering the pond.
Sources of seedlings : Fish species choose large-sized grass carp, carp, carp and carp species with strong constitution; relatives are mainly derived from wild Chinese sturgeon, and the larvae are cultivated under natural conditions, with neat specifications, good quality and no injury. Sick, no-resistance, healthy body, quick-moving, thin body, wide skirt, smooth and flexible, young children.
Seed disinfection : thoroughly remove the floating debris in the pool water before using the fish and the squatting pond to keep the water clean. Soak the fish for 10 minutes with 20 mg/high potassium manganate solution, then connect The fish is slowly poured into the pool with water, so as to minimize the stress reaction caused by the temperature difference; the cubs are soaked for 10 minutes with 3% salt solution before the pond, and the buckets with sputum are gently submerged into the water to make the cubs Climb yourself into the water.
Time of launch : In order to ensure seedling survival rate and make full use of water resources, fish species are placed on sunny days in the afternoon, and young cubs are placed on sunny days in the morning.
The number and proportion of stocking : 450 fish (485 tails/mu) of fish with the same specifications in each pool, 200-250 g/tail squid 220/pool, 250-300 g/tail squid 80 tails/pool, 250~400 g/tail grass carp 100 tails/pool, 50-75 g/tail squid 50 tails/pool; each pond stocking 200-250 g/only 250 cubs (270/ mu).
Second, feeding management
Types of bait : é³– is an omnivorous animal mainly based on animal feed. The whole feeding process mainly feeds fresh animal bait with high protein content (fish, crab, frog, snail, otter, green prawn, animal offal and Scraps, etc., supplemented with fresh pumpkin, radish strips, fruit pieces and vegetable leaves.
Source of bait: Animal bait is mainly self-cultivated squid, squid, squid, squid, grass carp and other fish and purchased wild fish and shrimp, crab, snail, snail, leeches and fresh animal viscera, etc. before feeding Wash with water and soak for 15 minutes with 3% salt solution; plant feeds such as water grass, duckweed, and vegetable leaves should be soaked for 15 minutes with 20 mg/L bleach solution.
Feeding time : When the water temperature in the pond rises to 18 °C, it begins to feed. At noon, it feeds a small amount of wild fish, frogs and other fresh bait for domestication, so that the cockroach eats the law and prolongs its growth period; 6~9 The month is the peak season for feeding and growing, and it is fed once a day in the morning and afternoon.
Feeding amount and frequency of bait feed : The daily feed amount is 10% of the total weight of the cockroach, and the fresh animal bait such as frog, snail, otter, fish and animal viscera fed 9%, fresh water grass and fruit block and Plant-based bait such as rape leaves accounted for 1%, and the animal's bait was increased by 5 kilograms for each kilogram of body weight gain; twice a day, and 40% of the total feeding amount in the morning (9-10 hours). (17~18 o'clock) Feed 60% of the total feeding amount throughout the day, and flexibly grasp the feeding amount of the day according to the weather, water temperature, water quality and food intake. Each feeding amount is é³–2~3 hours. More than 90% of the bait is concentrated in June feeding, the remaining bait is fed in May and October and after, the bait must be placed on the bait table regularly and quantitatively.
Fish bait and feeding : The carp and carp that are stocked in the polyculture pond mainly filter the plankton in the water. The squid can eat the slag residue and organic debris and use the waste directly; the grass carp is mainly water grass. Food, from mid-April to October, can put the right amount of duckweed into the pond.
Feeding method : The feeding of bait adheres to the principle of “four fixed†and “four looksâ€. "Four settings" is qualitative, quantitative, timing, and positioning. “Four Looksâ€, when you look at it, you can feed the bait according to the eating situation of the donkey. When the activity is normal and the food is strong, you should increase the bait. When the activity is not normal, you should reduce the feeding. When you look at the water, the water quality is good. If you want to invest more, you should invest less when the water quality is poor. If the water color is too light, you should cast more. If the water color is too dark, you should invest less. When the water color is green or sauce red, you can feed normally. When you look at the weather, the weather is fine and windy. More investment, cloudy or rainy days, less investment, when the weather is hot and there is no phoenix should stop feeding; four to watch the season, the high temperature in summer to control the amount of feeding, when the water temperature is low, to vote less.
Third, water quality regulation
The pool water is required to remain "fat, live, tender and cool". The squid is given high-quality organic fertilizer in front of the pond to make the water color green and the transparency of the water body reaches about 30 cm. When the water quality is too fat, it can be adjusted by adding new water or applying lime. In the spring and autumn, the water depth of the pool is maintained at 0.8~1.2 meters. With the increase of water temperature and the increase of the individual, the water level is gradually increased. The water level in the summer pool is kept at about 1.6 meters to ensure the water temperature is relatively stable; the water temperature is higher in the month, and the water is fed. Exuberant, residual bait and excrement increase, so add 1 new water every 15 days, add 20 cm each time, change water once a month, change 20%~30% of old water each time, every 15 ~20 days with lime (115 kg / mu · m) all the pool splashed once to adjust the water quality, to ensure that the pool of dissolved oxygen up to 4 mg / liter, ammonia nitrogen does not exceed 5 mg / liter, pH 7.0 ~ 8.5 Between the water body transparency is maintained at about 30 cm, basically reaching the water quality standards for pollution-free freshwater aquaculture.
Fourth, daily management
Persist in the early, middle and late patrols every day, check the entrance, drain and anti-escape facilities, prevent the idlers from entering the breeding area to create a quiet environment; clean up the fish, lick the leftover bait and debris, and the bait table Disinfect the food on the food court to keep the water fresh; observe the activity, feeding and growth of the fish and clams, as well as changes in water quality and water level, timely improve the water quality, adjust the feeding times and feeding amount, and do a good job in the breeding log. Record the weather, water temperature, water quality, use of bait and drugs, sick fish and cockroaches, disease control and fishing sales, etc., and find sick fish and sick stalks in time; at the same time, we must also achieve "five preventions", that is, prevention Floating head, anti-escape, anti-theft, anti-virus, anti-disease.
V. Disease prevention
Adhere to the disease prevention and control policy of “prevention first, anti-healing treatment, disease-free early prevention, early treatment of diseaseâ€, and effectively achieve “four eliminations†(ie pond disinfection, tool and food field disinfection, fish and carcass disinfection, feed Disinfect), keep the bait fresh, do not feed the rotten and deteriorated bait, add garlic to the bait every 15 days (mix 250 grams of garlic mixed with a blender per 50 kg of bait) and make a pellet to feed on the table. To prevent the occurrence of enteritis; monthly spray with 0.7 mg / liter of copper sulfate and ferrous sulfate mixture to prevent the occurrence of parasitic diseases.
