Tang carp, a tropical and subtropical fish, is widely distributed throughout southern China. It is both a nutritious consumer product and a tonic with medicinal properties; it can be sold both domestically and internationally. Therefore, the market has great potential and is an effective breeding target for farmers (fishers) to become rich. To this end, the artificial propagation and feeding techniques of pond fish are described below.
First, the shape and habits of pond carp Tang carp, the scientific name beard carp, in the classification is a scorpion-shaped, beard carp. Body length is generally more than 20 cm, weight 150 to 250 grams, the most about 500 grams. Tanggyu is originally a wild fish that inhabits the lower reaches of rivers, fields, pits, and ditches. Sexual gregarious, bulimia, feeding mainly on animal feed, such as insects, small fish, shrimp, shellfish and so on. Mostly at night activities and feeding, during the day they dive into the bottom or cave. After artificial rearing, they can also feed during the day and eat some of the vegetable concentrates. Tanggu fish have strong adaptability, can grow in small water bodies and low dissolved oxygen environment, have less disease, have a wide feed source, are easy to breed, and have low cost. They are suitable for small-surface farming promotion in farmyards.
Second, the broodstock broodstock bred farmer culture pond fish best self-breeding, self-breeding, self-support. The cultivation of broodstock is the top priority for successful breeding.
1. Pond conditions. The broodstock area is generally 35-350 square meters, and the water depth is 1.0-1.5 meters. The bottom of the pond does not have to be cemented, but it must be inclined to the drainage area so that the pool water can be completely discharged when the pond is cleared. Several culverts can be made in the pool corner or pool wall, or soil pipes or plastic hoses can be submerged in the pool to facilitate drainage capture. Ponds plant half of the surface of water lotus, duckweed, etc., in order to prevent the water temperature is too high in the summer and the water to maintain the appropriate darkness, quiet pond fish living environment.
2. broodstock selection. The mature period of females of pond catfish is generally 1 year, males 1.5 years. Therefore, we should choose 1.5 to 2.0 years old, large size, robust, weighing about 200 grams, without injury, disease-free broodstock. The best conditions for male and female breeding separately, placed in the pro-fish pond feeding 3 to 4 months before spawning.
3. Stocking and management. The broodstock stocking density is generally around 50 or so square meters. Feeding small trash fish, chicken, duck, fish and other animal organs, as well as rice bran, wheat bran, bean cake, peanut cake and so on. After minced animal feed, mixed vegetable feed and Vitas E, mineral trace elements, etc. are kneaded and fed in groups. Daily feeding varies depending on the water quality and climate. It is generally 3% to 5% of the body weight of the fish, but it must be reduced or stopped when the water quality deteriorates or the water temperature decreases.
Third, the cultivation of pond carp seedlings
1. Pond condition The seedling pool is generally an earthen pond of 20 to 100 square meters. The pool is surrounded with a salon net or a plastic plate to prevent encroachment. The bottom of the pond is inclined toward the outlet so that it can be completely drained during harvesting. Before the seedlings are released, the bottom of the tank must be dried and then flooded with fresh water. The water depth is 20-30 cm. A small plastic tube with a length of about 15 cm is placed on the bottom of the tank to allow it to hide and rest. The water pool does not grow beyond 1/2 of the total area. Floating lotus, duckweed and so on.
2. Fish fry The fry in hatchery box nets can be fed into seed ponds after the fourth day of feeding. Stocking density is 800-1000/m2. The early fish fry bait rotifers, leeches and other best.
3. Feeding In order to satisfy the initial fry of the fry, 15 days before fry stocking, another pool can be selected to cultivate blisters. The method is: drain the pool water, expose it to sunlight, and then put in lime water and manure, and put the water into it. The water depth is about 60 cm. About 2 weeks can allow the genus to multiply. When the fry begins to feed in the pool, it can be fed for 1 to 2 days. You can use hand-pick nets to collect leeches and other plankton in the broth to feed the fry. On the 8th day, silkworms and chopped shrimps and shellfish can be added. After 30 days, pig blood, mixed fish sauce, chopped animal internal organs and rice bran, wheat bran, soybean meal and other vegetable feeds can be fed. On the 40th day, a body length of 3 to 5 cm can be sold as fingerlings or transferred to adult fish ponds.
IV. Adult culture of pond carp
1. The construction of ponds can choose to build fishponds in the backyard of the farmhouse. In order to prevent pond fish from drilling holes in the pond, the wall should be cement or brick. If the pond is used, the wall of the pond should be thickened and hardened, and the bottom of the pond should be filled with gravel or clay soil. The pond area is generally 80 to 1,600 square meters, the pond embankment is 1.5 meters, the depth of the pond is 0.6 to 0.8 meters, the bottom of the pond is inclined to the drainage outlet, and the pond wall is made of several caves. The diameter of the pond is 13 centimeters in diameter and 5 meters in length. Pipes (cement or plastic) to facilitate the hiding and fishing of fish. Duckweed and other plants that grow no more than 1/2 of the total area in pond water.
2. The stocking period is generally 3 to 8 months each year. The stocking density is 3 to 5 cm. The fish species is 80 to 100 tails per square meter. The amount of sufficient feed and running water can be increased to 100 to 200 tails per square meter. .
3. Feeding pond squid omnivorous feeding can be fed either animal feed or plant feed. In order to adapt to the feeding habits of pond catfish, it is advisable to vote for the feeding time in the early morning and evening, or once in the evening. Feeding capacity is appropriately increased or decreased according to climate, water quality, and feeding intensity. Generally, the daily amount is 3% to 5% of the total weight of the fish.
4. Disease prevention pond disease is less common, common print and skin mildew. In the former, round spots of oval shape are formed on the fish body, as in the case of printing; the latter is covered with white hairs at the diseased site, and yellow mud is adhered to the hair. Treatment: Print disease can be used 1ppm bleach Quanchiposa; skin mold can be used 0.08% salt water Quanchiposa. At the same time, we must prevent the invasion of water snakes, frogs, rodents, and ferocious fish.
5. Fishing and transportation ponds Carp grows faster and can be raised for up to 120 grams in 3 to 4 months. After catching, the fish is placed in a small cement or brick pool for 1 or 2 days to drain the intestinal food and remove the mud taste before being shipped to the market. If transported over long distances, the fish should be loaded into an oxygen-filled nylon bag.
