CATDOLL : CATDOLL: What kind of feed does sweet osmanthus fish eat?

Question 1: What kind of bait does Mandarin fish like to eat? Mandarin fish can be fed with pellet feed in artificial breeding.

Mandarin fish, also known as Guiyu and Jihua fish, belongs to the order Perciformes and the genus Siniperca. It is widely distributed and breeds in major rivers and freshwater lakes. Mandarin fish has tender meat, few bones, delicious taste and rich nutrition. It is a delicacy on banquets and is favored by consumers. Not only can a small amount of mandarin fish be mixed in ponds to remove wild fish, but it can also be raised in special ponds. It is one of the popular species in freshwater aquaculture.

1. Living habits

Mandarin fish is a typical carnivorous fish. When artificially fed, it can be fed dead fish, dead shrimp, etc. Male fish mature at the age of three, and female fish mature at the age of four. Its growth rate is relatively fast, reaching 50-100 grams in the first year, about 0.5 kilograms in the second year, and 1-1.5 kilograms in the third year.

2. Pond conditions

The pond for breeding adult mandarin fish should be 3 to 8 mu in area, with a water depth of more than 1.5 meters, and about 2.5 meters in summer. The bottom should preferably be sandy loam with less humus, sufficient water source, fresh water quality, and preferably flowing water. The dissolved oxygen content of the pond water should be more than 5 mg/L, the pH value should be 7 to 8, and the transparency should be more than 30 cm.

3. Bait fish cultivation

The area for bait fish breeding is 3 to 4 times that of the mandarin fish pond. Considering the palatability and economics of mandarin fish, bait fish are generally selected from silver carp, crucian carp and other species, and the stocking density is 300,000 to 500,000 fry per mu. After the fry are released, they do not need to be fed immediately. When the number of zooplankton decreases and the fry are foraging around the pond, they can be fed with soy milk or other feed. In the early stage of breeding, feed is added when it is eaten up, and in the later stage, the size of bait fish should be controlled, and the length of bait fish should be controlled between 1/2 and 1/3 of the body length of mandarin fish.

Generally, when stocking 8 to 10 cm long mandarin fish, the size of bait fish should be controlled at 3 to 4 cm.

4. Stocking of Mandarin Fish

When raising mandarin fish alone, 800 to 1,000 mandarin fish of 8 to 10 cm in size can be placed per mu. Some fast-breeding fish can also be mixed in the mandarin fish pond as live feed. Generally, 200 to 400 pairs of tilapia broodstock or 60 two-winter crucian carp are placed per mu. Use a sparse net to divide the fish pond into two halves, and raise mandarin fish on one side.

Fish are raised while other fish are raised, so that the young fish can pass through the sparse net and become food for the mandarin fish. At the same time, the activities of the mandarin fish do not hinder the quiet reproduction of other fish.

5. Feeding and Management

1. Feeding: Feed fish at intervals. In the early and late stages of breeding, feed once every 7 to 10 days, and in the middle stage, feed once every 5 days or so. The ratio of mandarin fish to bait fish should be maintained at 1:5 to 10. Too few bait fish will affect the feeding and growth of mandarin fish, while too many bait fish will easily cause lack of oxygen and floating, which is not good for the growth of mandarin fish.

2. Water quality management:

It is necessary to frequently add new water, especially from June to September, add new water every 5 to 7 days, 15 to 20 cm each time, to keep the water rich, active, fresh and tender, and promote the healthy growth of mandarin fish. Submerged plants such as Vallisneria and Hydrilla verticillata can be planted around the pond to provide a hiding place for fish and purify the water quality. Sprinkle quicklime water once every 15 to 20 days, 15 to 20 kg each time. Open the aerator in a timely and reasonable manner to increase the dissolved oxygen content in the pond water to prevent fish from lacking oxygen. At the same time, some oxygenators should be prepared to rescue fish when they float to the surface due to lack of oxygen.

Question 2: What kind of food should be fed to mandarin fish in a fish tank? It is a carnivorous fish. It eats small fish and shrimps.

Question 3: What food does osmanthus fish usually eat? Osmanthus fish farming started in the South China Sea in 1987. In the past 20 years, it can be said that it has been prosperous, the farming area has been continuously expanded, and the farming level has been continuously improved. It reflects the welcome and love of consumers for osmanthus fish, reflects the good economic benefits of osmanthus fish farming, and conforms to market laws. 1. Create a good farming ecological environment 1. Pond conditions The water source, water quality, soil quality and surrounding environmental conditions should all meet the requirements of pollution-free farming. Pond area and water depth: 4D8 acres, water depth 2D2.5 meters, and the pond silt should be as little as possible. 2. Strict pond cleaning and disinfection One of the key technologies for raising osmanthus fish is strict pond cleaning and disinfection. Pond cleaning and disinfection should be carried out 8D10 days before cultivating "open bait fish" and osmanthus fish species. If conditions permit, it is better to do it about half a month in advance. The pond bottom can be exposed to the sun after pond cleaning and disinfection. Pond cleaning and disinfection drugs include quicklime, bleaching powder, chlorine dioxide, sodium dichloroisocyanurate, trichloroisocyanuric acid, dichlorohydantoin, bromochlorohydantoin and tea dregs. It is recommended to use 20kg quicklime + 1 bag of pond cleaning net per mu for thorough pond cleaning at the beginning of the year. ① Quicklime: freshly baked or well-preserved ash blocks are required for dry pond cleaning, with a dosage of 125-150 kg per mu. The effect of quicklime pond cleaning disappears in 7-10 days. ② Tea dregs: Tea dregs are used to clean ponds with water. After being crushed, the tea dregs are soaked for 6-12 hours, then mixed with water and sprinkled throughout the pond. Tea dregs have no bactericidal and disinfecting effects, so they must be used in conjunction with bactericidal and disinfecting drugs. Use 40-45 kg of tea dregs per mu of water surface and per meter of water depth, and then use 13.5 kg of bleaching powder, or 2500 g of trichloroisocyanuric acid, or 300 g of dibromohydantoin. 2. Stocking healthy, high-quality, and appropriate-sized fish 1. Standards for healthy, high-quality sweet-scented osmanthus fish seedlings: ① Seedlings that are not inbred; seedlings that mature once or twice in the same year; ② Seedlings in the same batch and in the same pond have uniform specifications; ③ Well-fed; ④ Wide body, large and obvious side stripes, bright body color, and no injuries; ⑤ In a natural state, they gather underwater in groups; except for hunting, they do not swim to the surface of the water, and rarely move, and stay underwater; when they are still, their heads are slightly tilted downward and their tail stalks are bent. If they are picked up in a basin, they will move around lively at first, then they will be still and will not lie on the bottom of the pond; ⑥ The deformity rate is less than 3%. 2. Appropriate stocking specifications It is most appropriate to buy sweet-scented osmanthus fish seedlings with a size of 2.5-3.5cm. Sweet-scented osmanthus fish seedlings of this size can be directly put into the pond for cultivation or marked, which is cost-effective, convenient to transport, with low transportation costs and high survival rate. The purchased 2.5-3.5cm sweet-scented osmanthus fish fingerlings should be cultivated to about 10cm or 40-50g before being raised in ponds. The 2.5-3.5cm sweet-scented osmanthus fish fingerlings are cultivated to 10-12cm, with a cultivation density of 6000-8000 tails/mu and a cultivation time of 25-30 days. The 2.5-3.5cm size is cultivated to 40-50g, with a cultivation density of 4000-5000 tails/mu and a cultivation time of 40-50 days. Technical points: ① Cultivate enough palatable bait fish before the sweet-scented osmanthus seedlings are put into the pond, and the pond water and bait fish are strictly disinfected and killed. Disinfect 1-2 days before the release of sweet-scented osmanthus fish fingerlings, and use ginger + fiber spray to disinfect and kill insects for each set of 1 mu 1 day in advance or on the day of seeding to reduce stress response. ② Timely supplement palatable feed fish. The size of feed fish should be appropriately small under the premise of being palatable, and the amount of each feeding should be eaten up in about 5 days. Before each feeding, the feed fish must be disinfected and sterilized by drug bathing. ③ When the breeding standard reaches the predetermined specifications, choose a cool weather to catch fish in the morning and transfer them to the pond for breeding. ④ Before transferring the fish to the pond, select the specifications and eliminate the weak and deformed individuals. A mildew disease package + ginger spraying with a dosage of 1 mu per set can be used to reduce secondary infection complications. 3. Fish stocking time The stocking time of fish affects the growth rate, feed coefficient (production cost), disease occurrence frequency and market price of sweet-scented osmanthus fish. The early or late stocking time is proportional to the growth rate and inversely proportional to the feed coefficient. The early stocking has a fast growth rate and a low feed coefficient. Usually, the growth rate of stocks released before May is particularly fast and the feed coefficient is low (between 3.5-4.5). The growth rate of stocks released after mid-July is slower and the feed coefficient is higher (5-8). The main reasons for this phenomenon are: (1) climate and water temperature conditions; (2) seedling germplasm factors. ......>>

Question 4: Mandarin fish eats pellet feed. Mandarin fish belongs to the genus Siniperca chus of the family L. The body is relatively high and flat on the sides. The back is bulging. The jaw is more obvious than the jaw. The jaw, vomer, and operculum have equal teeth. The preoperculum margin is serrated with 4 spines; the operculum margin has 2 spines with fine scales; the lateral line is curved along the dorsal arc. The two parts of the dorsal fin are connected to each other. The front hard spines and soft fin rays are yellow-green. The abdomen is gray-white. The sides of the body have regular dark brown spots and plaques; from the tip of the snout through the eye socket to the front of the dorsal fin, there is a narrow black stripe

Mandarin fish breeding technology

Fish species for feeding sweet-scented osmanthus fish in ponds: silver carp, bighead carp, dace, wheat dace, Thai dace, crucian carp, carp, etc. The bait coefficient is generally 4-5. According to the feeding amount of sweet-scented osmanthus fish, a pond 3-4 times the area of ​​the sweet-scented osmanthus fish pond is used for breeding and producing sufficient bait fish for feeding sweet-scented osmanthus fish.

1. Early bait fish: Prepare the pond for stocking sweet-scented osmanthus fish. Stock silver carp, bighead carp, dace, wheat dace, Thai dace, crucian carp and other fish fry (fish flowers) 1-2 million per mu as early bait fish for sweet-scented osmanthus fish. Feed them with bran, wheat bran and other roughage. After 15-20 days, cultivate the bait fish until they are 15-25 cm in size. Use 0.7ppm copper sulfate and 0.5ppm strong chlorine to kill insects and disinfect. Then put them into the 2-3cm sweet-scented osmanthus fish fry for cultivation.

2. Bait fish: 200,000 to 300,000 fry of Tulin, Mailin, Tailin, etc. are mixed in four fish ponds per mu. Special ponds are used to cultivate silver carp, bighead carp, crucian carp, etc. fry as standard osmanthus fish bait fish.

3. Bait fish: In addition to self-production and self-sufficiency, purchase from outside during the breeding period. In winter, dace bait fish are prone to freezing to death. You should cultivate and prepare some cold-resistant species such as silver carp, bighead carp, and crucian carp to overwinter and use them as bait fish for sweet-scented osmanthus fish in winter and spring.

At present, the best season for stocking mandarin fish is now the key points of pond farming technology:

1. Pond conditions: The pond area is generally 2-4 mu, the water depth is about 2 meters, the water quality is fresh, the bottom mud is small, or the drainage and oxygenation equipment is complete.

2. Cultivation of bait fish: According to the principle of palatability, economy and low cost, silver carp, white carp, bream, silver carp, bighead carp and other fish fry are selected as bait fish. The idle period before stocking in the sweet-scented osmanthus fish pond is used to cultivate the early bait fish. Self-breeding crucian carp or bream fry are put in about 20 days before the release of sweet-scented osmanthus fish. The stocking volume is 400,000 to 600,000 tails per mu. They are fed with soybean milk or other feed. During the feeding period, bait fish must be raised in a special pond. It is advisable to adopt high-density breeding in the pond. The fish are gradually dehydrated after being caught to ensure that the bait fish and sweet-scented osmanthus fish are synchronized.

3. Mandarin fish stocking: Stocking time is generally in June. Specifications require 6-10 hectares. The stocking rate is high and the speed is fast. Generally, the stocking amount per mu is 500-800.

4. Feeding of bait fish: During the fish breeding period, it is necessary to ensure that every fish is full. It is better to feed less bait fish. If the fish is hungry, it will affect the fish or cause cannibalism.

5. Water quality control: The water quality of the mandarin fish pond should be controlled and water should be changed frequently. During the high temperature season from June to September, the water should be drained and replaced every week. The water should be changed by 0.4 m per time to maintain the transparency of the pond water at 40 cm.

Tips for stocking mandarin fish

, Fishing

1. The current value of fish seed sources. In hot seasons, the temperature is high and the fish species are weak. Generally, it is easy to transport them on the road. The stocking of fish seed sources should be adjusted to solve the fishing requirements in nearby waters. The fishing point of fish species should be close to the stocking point. The fishing and stocking should be closely connected. The fish species can be caught and stocked at the same time. If they are to be temporarily raised in net cages or blocked and pulled nets, the operation room should be more than two. It is strictly forbidden to operate fish species out of water.

2. Fishing for species. The principle of "catch fast and release lightly" should always be adhered to when catching and raising fish. Fishing must be done carefully and slowly. Try to avoid hurting the fish. The fishing time should be determined in the morning and evening when the weather is cool. Fishing tools should be drag nets, set nets and other tools that hurt the fish. Drag nets should be used in the same water. The number of drag nets can cause fish to float and die. The wire nets can hurt the fish and cause the fish scales to fall off. Dried ponds should be used for catching. The sewage can choke the fish to death. Shallow water can burn the fish. Feed the grazing fish. Use medicated bait to lure them. Nets should be used to intercept their routes for collective capture.

2. Fish stocking management

1. Preparation before stocking. Before stocking fish, various preparations should be made to check whether the water inlet is complete to prevent leakage. If any problems are found, they should be solved immediately. In addition, the water body conditions should be observed, especially the situation of fish escaping from the pond should be understood to understand the details in order to determine the stocking species and stocking quantity. The water body should be improved. Due to the high temperature, the water body is generally turbid, the water is polluted, the water quality is poor, and bacteria are easy to reproduce. Lime or alum should be used to spray water to clarify the water body and purify the water quality. If the water body is thin, fertilizer should be applied to cultivate water and bait.

2. Stocking operation: Reduce stocking mortality, ensure stocking effect, and select supplementary fish species. The selection of fish species requires complete scales and fins, strong jumping ability, and swimming physique. Fish with fat bodies, sick and injured bodies, thin bodies, slow reactions, body congestion, and mechanical damage should all be eliminated. The stocking species should be determined according to the source of fish species and stocking needs. The stocking density should be adhered to the principle of sparse stocking so that all bottom fish can reach commercial specifications, reduce the impact of short-term benefits, and ensure aquaculture benefits. The stocked fish species must be disinfected with drugs before being put into the water to prevent fish from entering the pond with diseases and causing the spread of fish diseases. Generally, they should be soaked in 2% to 3% salt water or 1ppm to 2ppm crystal trichlorfon for 3 to 5 minutes.

3. Stocking management: Fish stocking should be carefully managed according to the stocking species and quantity, such as feeding, fertilization, and water quality.

Question 5: Regarding Osmanthus fish, does Osmanthus fish only eat live small fish? Can it not survive with other feed or dead things? I think so. We have a large reservoir here. Other fish are raised by people, such as black carp, turtle, etc. However, no one raises Osmanthus fish and Qiaozui fish.

Question 6: What does the sweet-scented osmanthus fish eat? Mandarin fish is commonly known as: Mandarin fish, seasonal flower fish, sweet-scented osmanthus fish, Gui fish, fish. Mandarin fish generally live in still water or slow-flowing water bodies, especially in lakes with lush aquatic plants. They are not very active in winter and often hibernate in deep water. They generally do not completely stop eating. When the weather warms up in spring, they swim to shallow waters along the coast to find food; at this time, both male and female fish have the habit of lying on their sides in the sunken places at the bottom of the lake during the day, and move and forage in the aquatic plants at night. They mainly feed on other fish. Their feeding is poor in January and February, and is most vigorous in June and July. The feeding intensity decreases slightly during the reproductive period. Mandarin fish usually grow to 2 winters old, and in the northeast, they reach sexual maturity in 3 winters old. Parents gather in groups to spawn in a gentle flowing water environment at night from May to July. June and July are the peak spawning period, with a carrying capacity of 30,000 to 200,000 eggs.

Question 7: At what temperature does the mandarin fish eat? The mandarin fish is also known as the sweet-scented osmanthus fish, and belongs to the genus Siniperca of the family L. The body is relatively high and laterally flattened, with a bulging back. The mouth is large, and the lower jaw is significantly longer than the upper jaw. There are small teeth of varying sizes on the upper and lower jaws, the vomer, and the operculum. The rear edge of the preoperculum is serrated, with 4 large spines on the lower edge; there are 2 large spines on the rear edge of the postoperculum. The head is scaly, and the scales are small; the lateral line bends upward along the dorsal arc. The dorsal fin is divided into two parts, connected to each other, with hard spines in the front and soft fin rays in the back. The body is yellow-green, the abdomen is grayish white, and there are irregular dark brown spots and patches on the sides of the body; there is a narrow black stripe from the tip of the snout through the eye socket to the front and bottom of the dorsal fin.

The types of bait fish for osmanthus fish in ponds include silver carp, bighead carp, ding, wheat ding, Thai ding, crucian carp, carp, etc. The bait coefficient is generally 4-5. According to the growth specifications and food intake of osmanthus fish, a pond 3-4 times larger than the area of ​​osmanthus fish pond is used to cultivate and produce sufficient bait fish to feed osmanthus fish.

1. Early bait fish: 1-2 million fish fry (fish flowers) of silver carp, bighead carp, ling, wheat ling, Thai ling, crucian carp, etc. should be stocked per mu in the pond where osmanthus fish is to be stocked as early bait fish for osmanthus fish. Feed them with coarse feed such as peanut bran and wheat bran. After 15-20 days of cultivation, when the bait fish grow to 1.5-2.5 cm in length, use 0.7ppm copper sulfate and 0.5ppm strong chlorine to kill insects and disinfect, and then put in 2-3 cm osmanthus fish fry for cultivation.

2. Mid-term bait fish: 200,000 to 300,000 fry of local carp, wheat carp, Thai carp and other fish can be raised per acre in the four major carp ponds. You can also cultivate silver carp, bighead carp, crucian carp and other fish fry in special ponds as bait fish for large-sized osmanthus fish.

3. Late-stage bait fish: In addition to self-production and self-sufficiency, you can also purchase from outside. In the late stage of breeding, it is generally winter, and the bait fish of the dace are easy to freeze to death. You should cultivate and prepare some cold-resistant species such as silver carp, bighead carp, and crucian carp to overwinter and use them as backup bait fish for osmanthus fish in winter and spring.

Now is the best season for stocking mandarin fish. The key points of pond culture technology are introduced as follows:

1. Pond conditions: The pond area is generally 2-4 mu, the water depth is about 2 meters, it is mainly rectangular, the water quality is fresh, there is little or no bottom mud, and the drainage, irrigation and oxygenation equipment are complete.

2. Cultivation of bait fish: Based on the principle of good palatability and low economic cost, silver carp, white carp, bighead bream, silver carp, bighead carp and other fish fry can be selected as bait fish. Use the idle period before stocking the sweet-scented osmanthus fish pond to cultivate early bait fish. You can breed crucian carp or bream fry yourself, or you can put various fry about 20 days before the release of sweet-scented osmanthus fish. The stocking amount per mu is 400,000 to 600,000. The feeding method is to feed with soybean milk or other feed. The bait fish in the middle and late stages must be raised in special ponds. It is advisable to adopt a multi-pond high-density breeding method, catch them in batches, and gradually loosen them to ensure that the bait fish grow synchronously with the sweet-scented osmanthus fish.

3. Stocking of Mandarin fish: The stocking time is generally in June, and the stocking size is required to be 6-10 cm. The advantage is that the survival rate is high and the growth rate is fast. Generally, the stocking amount per mu is 500-800 fish.

4. Feeding of bait fish: During the breeding period of adult fish, it is advisable to ensure that they are full every day. If there are too few bait fish and they are hungry, it will affect the growth of mandarin fish or cause cannibalism.

5. Water quality control: The water quality of the mandarin fish pond should be well controlled and water should be changed frequently. The high temperature season from June to September is the peak feeding season. The water should be filled and drained once a week, with 0.4 cubic meters of water changed each time, and the transparency of the pond water should be kept above 40 centimeters.

Tips for stocking mandarin fish

1. Sources and fishing of fish species

1. Source of fish species. Now is the hot season, the temperature is very high, and the fish species are weak, which is generally not convenient for long-distance transportation. The source of supplementary fish species is mostly solved by local adjustment, or they can be caught in natural waters nearby. The fishing site of the fish species is required to be very close to the stocking site, and the fishing and stocking should be closely connected. The fish species should not be out of water for too long, and it is best to catch and stock at the same time. If it is not possible for the time being, you can temporarily raise them in a net cage or stop them in a dragnet for operation, but the time should not exceed two hours. It is strictly forbidden to operate fish species out of water.

2. Fishing and raising of fish species should always adhere to the principle of catching quickly and releasing lightly. When fishing, you must be careful and slow, and try not to hurt the fish. The fishing time can be determined in the morning and evening when the weather is cool. The fishing tools should be large drag nets, set nets, etc. that do not hurt the fish. When fishing in the same water body, the number of times the net is pulled should not be too many, otherwise the fish will float and die. Wire nets will hurt the fish and make the fish scales fall off, so don't use them. Fishing in a dry pond will choke the fish with sewage and burn the fish due to shallow water, so it's best not to use it. For...>>

Question 8: There are many types of feeds and brands for breeding mandarin fish. You can choose the one that suits your own breeding. It mainly depends on your own use. Because the environment of each farm is different, you don’t have to use big brands. Look at the news now that big brands have also had problems. I use Wuhan Huamu’s laying hen feed, which is pretty good and has received good feedback, especially the feces, which are very well formed and delicate, and the feed is well digested and absorbed, which improves the utilization rate of the feed.

Question 9: What kind of bait does Mandarin fish eat? Mandarin fish can be fed pellet feed in artificial breeding.

Mandarin fish, also known as Guiyu and Jihua fish, belongs to the order Perciformes and the genus Siniperca. It is widely distributed and breeds in major rivers and freshwater lakes. Mandarin fish has tender meat, few bones, delicious taste and rich nutrition. It is a delicacy on banquets and is favored by consumers. Not only can a small amount of mandarin fish be mixed in ponds to remove wild fish, but it can also be raised in special ponds. It is one of the popular species in freshwater aquaculture.

1. Living habits

Mandarin fish is a typical carnivorous fish. When artificially fed, it can be fed dead fish, dead shrimp, etc. Male fish mature at the age of three, and female fish mature at the age of four. Its growth rate is relatively fast, reaching 50-100 grams in the first year, about 0.5 kilograms in the second year, and 1-1.5 kilograms in the third year.

2. Pond conditions

The pond for breeding adult mandarin fish should be 3 to 8 mu in area, with a water depth of more than 1.5 meters, and about 2.5 meters in summer. The bottom should preferably be sandy loam with less humus, sufficient water source, fresh water quality, and preferably flowing water. The dissolved oxygen content of the pond water should be more than 5 mg/L, the pH value should be 7 to 8, and the transparency should be more than 30 cm.

3. Bait fish cultivation

The area for bait fish breeding is 3 to 4 times that of the mandarin fish pond. Considering the palatability and economics of mandarin fish, bait fish are generally selected from silver carp, crucian carp and other species, and the stocking density is 300,000 to 500,000 fry per mu. After the fry are released, they do not need to be fed immediately. When the number of zooplankton decreases and the fry are foraging around the pond, they can be fed with soy milk or other feed. In the early stage of breeding, feed is added when it is eaten up, and in the later stage, the size of bait fish should be controlled, and the length of bait fish should be controlled between 1/2 and 1/3 of the body length of mandarin fish.

Generally, when stocking 8 to 10 cm long mandarin fish, the size of bait fish should be controlled at 3 to 4 cm.

4. Stocking of Mandarin Fish

When raising mandarin fish alone, 800 to 1,000 mandarin fish of 8 to 10 cm in size can be placed per mu. Some fast-breeding fish can also be mixed in the mandarin fish pond as live feed. Generally, 200 to 400 pairs of tilapia broodstock or 60 two-winter crucian carp are placed per mu. Use a sparse net to divide the fish pond into two halves, and raise mandarin fish on one side.

Fish are raised while other fish are raised, so that the young fish can pass through the sparse net and become food for the mandarin fish. At the same time, the activities of the mandarin fish do not hinder the quiet reproduction of other fish.

5. Feeding and Management

1. Feeding: Feed fish at intervals. In the early and late stages of breeding, feed once every 7 to 10 days, and in the middle stage, feed once every 5 days or so. The ratio of mandarin fish to bait fish should be maintained at 1:5 to 10. Too few bait fish will affect the feeding and growth of mandarin fish, while too many bait fish will easily cause lack of oxygen and floating, which is not good for the growth of mandarin fish.

2. Water quality management:

It is necessary to frequently add new water, especially from June to September, add new water every 5 to 7 days, 15 to 20 cm each time, to keep the water rich, active, fresh and tender, and promote the healthy growth of mandarin fish. Submerged plants such as Vallisneria and Hydrilla verticillata can be planted around the pond to provide a hiding place for fish and purify the water quality. Sprinkle quicklime water once every 15 to 20 days, 15 to 20 kg each time. Open the aerator in a timely and reasonable manner to increase the dissolved oxygen content in the pond water to prevent fish from lacking oxygen. At the same time, some oxygenators should be prepared to rescue fish when they float to the surface due to lack of oxygen.
