How to raise garfish How to raise garfish

1. Pond selection, cleaning and disinfection. Choose a fish pond with good water quality and sufficient water source, with a water depth of more than 1.5m and an area of ​​2-10 mu. For ponds with more than 10cm of silt at the bottom of the pond, the excess silt must be removed. After removing the excess silt, do not add water immediately, but expose it to the sun for several days before cleaning and disinfection. 10-15 days before stocking, dissolve 50-75 kg of quicklime or 7-10 kg of bleaching powder per mu into a slurry and sprinkle it throughout the pond.

2. Fish stocking and species matching. Fish stocking is usually carried out in winter or early spring, with a stocking size of 20 grams or more per fish and a stocking density of 2,000 to 3,000 per mu. Before stocking, fish should be soaked in 3-5% salt water for 10 to 15 minutes before stocking. At the same time, silver carp and bighead carp are matched with summer fish, with 1,000 silver carp per mu and 3,000 bighead carp per mu.

3. Preparation and feeding of bait. Pelteobagrus fulvidraco is mainly carnivorous. If conditions permit, you can directly mince small fish, shrimp, snail and clam meat, livestock and poultry scraps and other animal baits, use 3-8% flour as a binder, stir thoroughly, and feed them on the feed table. When the above animal raw materials are scarce, you can make pellet feed according to the formula of 30% fish meal, 30% bean cake, 20% bran, 10% corn, 6% flour and 4% fish oil and minerals. You can also buy full-price yellow catfish compound feed from professional manufacturers for feeding. Feeding adopts the "four fixed" principle, feeds twice a day, and the daily feeding rate is controlled between 5-8%, which can be flexibly controlled depending on the fish's feeding, weather, water temperature and other conditions.

4. Daily management and disease control. It is very important to regulate the water quality of the main breeding of yellow catfish. Since May, new water should be added every 10-15 days, and 10-15cm of water should be added each time. If the water quality is found to be too rich, some old water should be discharged in time and new water should be added to ensure that the fish have a strong feeding and normal growth. Patrol the pond every day, manage the feeding table and food well, check the fish body and keep fish farming records. At the same time, disease prevention and control work should be carried out in accordance with the principle of "prevention first, prevention and control combined". In the season of fish disease epidemics, 1ppm bleaching powder or 25ppm quicklime should be sprinkled in the whole pond every 10-15 days. During daily pond patrols, pay attention to the activities of the fish, detect the disease early, treat it in time, and prevent the disease from spreading. Yellow catfish is a scaleless fish and is more sensitive to drugs. Drugs such as trichlorfon and copper sulfate should be used with caution.

How to breed Wangya fish

In the "Chinese Aquatic Products Catalog", the real name of "Wang Ya Fish" is Yellow Catfish. It mostly lives in the bottom of the lake or slow-flowing rivers, especially in shallows with decaying materials and silt. It lurks at the bottom of the water body during the day and floats to the upper layer of the water to find food at night. In winter, it gathers in the deep water of tributaries. It has a strong ability to adapt to the environment, so it can survive in adverse environmental conditions. Yellow Catfish is a typical omnivorous fish. The young fish mainly feed on zooplankton and larvae of aquatic insects, and the adult fish feeds on small fish and invertebrates. Yellow Catfish reaches sexual maturity at the age of 2. From May to July every year, the male fish swims to the silt and clay with dense aquatic plants in the coastal area (water depth of 8-40 cm), and uses the pectoral fins to rotate intermittently on the mud bottom to dig a small mud pit, which is the fish nest for spawning. After the male fish builds the nest, it stays in the nest, waiting for the female fish to come and lay eggs and fertilize in the nest. Spawning activities usually take place at night when the weather changes from sunny to rainy. After laying eggs, the female fish leaves the nest to look for food, and only the male fish guards the developing eggs and fry near the nest until the fry can leave the nest and swim freely (about 7-8 days). At present, the breeding of yellow catfish is quite extensive, and it is the main breeding species for fishermen and farmers in many places to increase their income. However, in the breeding process, many farmers do not know how to save feed because of the one-sided pursuit of output. They continue to put too much feed and fertilizer into the breeding water, which not only increases the breeding cost, but also causes the water quality to deteriorate, affecting the growth of yellow catfish and resulting in low breeding efficiency. How to save feed costs in production practice?

Strictly remove debris, clean the pond and disinfect it. Cleaning and disinfecting the pond can not only kill wild fish and reduce the competition for food, but also kill pathogenic factors in the water, improve water quality, and provide a good feeding and growth environment for yellow catfish. There are many wild fish and shrimps in the pond, which will compete with yellow catfish for bait. Fierce fish will even eat the yellow catfish, reducing the utilization rate of feed, so they should be removed.

Before stocking the seedlings, both old and new ponds must be cleaned and disinfected. Excessive silt should be removed from old ponds, leaving only 10 cm of bottom mud. Use drugs to clean and disinfect the pond 10 to 15 days before stocking the fish to kill pathogens and predators in the aquaculture water. Generally, two methods can be used: dry pond cleaning or water pond cleaning. When dry pond cleaning, about 75 kg of quicklime or 4 to 5 kg of bleaching powder can be used per mu; when water pond cleaning, about 150 kg of quicklime can be used per mu to sprinkle the entire pond, and try to mix the mud at the bottom of the pond with quicklime to completely kill parasites, pathogens and wild fish, etc., reduce the objects of competition for food, and improve feed utilization. Pond breeding of yellow catfish requires deep water, sufficient water source, good water quality, and drainage and irrigation. Therefore, it is advisable to choose a pond with an area of ​​2 to 5 mu, requiring a stable and sufficient pollution-free water source, and the water quality must meet the aquaculture water standards. The pond is easy to drain and has a flat bottom, which can protect the fish from 1.5 to 2 meters deep. However, if the water depth is not deep enough, the light is too strong, which is not suitable for the yellow catfish's habit of feeding under weak light. Before stocking the fish, sufficient basal fertilizer should be applied. Generally, fermented organic manure is applied to improve the water quality, with a dosage of 150 to 200 kilograms per mu. Fish are then released after a large number of zooplankton appear in the pond water.

Pay attention to reasonable stocking. Reasonable stocking density can improve feed utilization; suitable matching varieties can make full use of feed, mutually beneficial symbiosis, achieve harmony in the water body, and improve feed utilization efficiency. In order to make the survival rate of yellow catfish farming high and reduce feed waste, the stocking density and the matching fish must be controlled. When releasing fish species, large-sized fish species of about 30 grams per tail should be selected for adult fish breeding. The stocking amount of fish species can be flexibly controlled according to the conditions of the pond, management level, feed supply and fish species specifications. The stocking density should be appropriate. If it is too sparse, the utilization rate of the fish pond is not high and the efficiency is low. If it is too dense, the fish grows slowly and induces diseases; the matching should be reasonable, with the premise of making full use of the water layer space of the fish pond and not competing for food. Generally, about 1,500 yellow catfish species of 30 grams per tail can be released per mu, and about 200 silver carp of 50 grams per tail can be matched. The fish species to be released should be of uniform size, bright color, smooth body surface, free of disease and injury, intact fins, and strong physique. They should be soaked in 5% salt water for 10 minutes before entering the pond. Yellow catfish are generally released in late April each year, and the silver carp should be released half a month after the yellow catfish enters the pond to facilitate its growth. In addition, as the fish grows, in order to adjust the breeding density and improve efficiency, they can be caught and released in batches and in rotation to adjust the fish load in the water and improve the feed return rate.

Scientific fertilization and feeding The amount of macro-aquaculture inputs such as fertilizers and baits affects both the growth of yellow catfish and the changes in water quality. The food of yellow catfish in natural waters is mainly shrimp, fish and fish eggs and some aquatic insects and aquatic plants. Therefore, artificial breeding can be carried out with fresh animal baits such as small fish and shrimp, livestock and poultry processing scraps, etc., and can also be fed with bean cakes, peanut cakes, bran, etc. Homemade compound baits are generally used for domestication and feeding. The bait is made of imported fish meal, meat and bone meal, blood meal, soybean meal, rapeseed meal, dried fish worms, etc. and feed additives. The protein content in the early stage is more than 35% to 45%, and the crude fat content is 5% to 8%; in the later stage, small fish meal can be used to replace part of the imported fish meal, with a protein content of 30% and a fat content of about 6%. The reference formula is: fish meal 25%, bean cake 20%, vegetable cake 30%, wheat flour 20%, corn flour 3%, minerals 2%, vitamins 0.2%. The bait must be fresh and free of mold and corruption. It is advisable to choose complete compound feed produced by regular manufacturers. When feeding, pay attention to the principle of "domestication and feeding, early feeding, and small and frequent meals". Wild yellow catfish likes to hide during the day and come out to feed at night. After 5 to 7 days of domestication under artificial breeding conditions, it can be fed on the feeding table during the day. Artificial feeding is used for domestication 2 days after the seedlings enter the pond. During domestication, fixed feeding signals are used for fixed-point and regular feeding training. After patient domestication for 5 to 7 days, it will be normal; the domesticated seedlings released in this way can be fed normally on the second day after entering the pond. The feeding method can be artificial or mechanical feeding. When feeding, it is necessary to start eating early and eat small and frequent meals. The entire feeding process should be divided into three stages. In the first stage, feed 4 times a day in May and June, with a daily feeding rate of 3% to 5%; in the second stage, feed 3 times a day from July to September, with a feeding rate of 2% to 3%; in the third stage, feed 2 times a day after October, with a feeding rate of 2%, and feed during the period of high dissolved oxygen every day. On this basis, the amount of feed should also be adjusted according to the weather and water quality. In addition, since the mouth of yellow catfish is large, the particle size of the feed should be increased accordingly. The particle size of 2 mm is used as the opening feed, and the particle size of the adult fish feed can reach more than 5 mm. The use of sinking hard granular bait requires the particles to be stable in the water for 15 minutes, and the use of floating bait will better improve the utilization rate of bait.

Regularly adjust the water quality. To raise fish, you must first raise the water. The quality of water affects the growth rate and feed coefficient of yellow catfish. Yellow catfish likes fresh water. Good water quality means rapid growth and fewer diseases. It can make full use of feed and reduce the feed coefficient. In the breeding of adult yellow catfish, water quality management is the most critical, and a fresh water environment needs to be maintained. In order to prevent water aging, water is injected once a month in May and June, and 30 cm of new water is replaced each time. From June to September, water is replaced once every half month, and about 15 cm of water is replaced each time, and the water depth is maintained at 1.2 meters to 1.5 meters. Regular disinfection is carried out. From June to September, 15ppm quicklime is used to spray the entire pond once a month to purify and disinfect the water quality and reduce excessive organic suspended matter in the water. 5 kg of quicklime (or 2 kg of bleaching powder) is used for local treatment in the feeding area and aerator every half month. Keep observing the algae phase and algae concentration in the water body, and adjust the water body fertility with inorganic fertilizers (urea, superphosphate, potassium dihydrogen phosphate, etc.) according to the water color, and keep the transparency at 30 cm to 35 cm. Use the aerator scientifically according to the determination of dissolved oxygen and the weather and water quality conditions. On sunny days, keep turning it on for 1 hour in the early morning and afternoon. On rainy and hot weather, make full use of mechanical aeration to supplement the lack of dissolved oxygen in the water body. The dissolved oxygen should be maintained at more than 3 mg/L.
