CATDOLL : CATDOLL: How many catfish seedlings should be planted per acre?

How many yellow catfish seedlings are planted per acre?

The number of fry to be released per mu for breeding yellow catfish depends on factors such as breeding conditions, breeding methods, feed supply, fish species specifications, and management level. If it is conventional breeding, usually 2500-5000 fish with a size of 15-35 grams per tail can be released per mu. Larger fish can be matched with appropriate amounts of silver carp and bighead carp. If it is a mixed breeding model, 100-150 fry with a size of more than 30 grams per tail can be released per mu.

How many seedlings should be planted per acre for yellow catfish?

How many yellow catfish seedlings are stocked per mu is mainly related to factors such as breeding conditions, breeding methods, feed supply, fish species specifications, and management level. Under conventional breeding conditions (mainly yellow catfish), 15-35 grams per tail can usually be stocked at 2,500-5,000 tails per mu. When the size is larger, it can be appropriately sparsely stocked. At the same time, about 200 silver carp and bighead carp can be stocked to adjust the water quality. If a mixed breeding model is adopted, yellow catfish can be raised in other breeding ponds, and yellow catfish weighing more than 30 grams per tail can be raised at 100-150 tails per mu.

2. Breeding method of yellow catfish fry

1. Choose a fish pond

(1) The pond area for breeding yellow catfish should be 1-3 mu. The water source near the pond should be sufficient and the water quality should not be polluted. At the same time, the pond should be easy to drain and irrigate. It is recommended to prepare more water pumps for drainage and irrigation.

(2) If there is excess silt in the pond, it must be cleaned up completely. The thickness of the silt only needs to be kept at about 10 cm. Finally, the dam must be inspected and repaired to prevent leakage.

2. Disinfection of nutrients

(1) Kill all the wild fish, pathogens, parasites and other organisms that are harmful to yellow catfish in the fish pond. Generally, about 150 kg of quicklime can be used per mu, and then clean water is injected into the pond to a depth of 30-40 cm. When injecting water, use a fine net to filter the water to prevent wild fish and hostile organisms from entering the pond.

(2) Finally, sprinkle 4-5 kg ​​of "Bio-Fertilizer Water King" to cultivate natural bait. You can also apply 3-4 kg of farmyard manure, such as livestock manure. After completing these preparations, you can start raising seedlings.

3. Stocking fish fry

(1) 30,000 to 50,000 fish fry should be stocked per mu of pond. Note that yellow catfish is suitable for single-breeding and cannot be mixed with other fish species such as carp and crucian carp. The stocked fish fry should preferably be hatched at the same time. If the sizes of the fish fry are different, the survival rate of the fish fry will be reduced.

(2) When stocking fish fry, you should also pay attention to testing the pH and temperature of the pond water. The water temperature in the pond should not exceed 20°C, and the pH value should be between 6.8-7.5.

4. Feeding

(1) In the early stage, the fry will forage in groups. If there is sufficient natural bait, there is no need to feed them additional food. If there is a lack of natural bait, they need to be fed rotifers artificially and the amount of farmyard manure should be increased. Soy milk can also be sprinkled every morning and evening to speed up the reproduction of plankton.

(2) When the fry grow to a length of 2-3 cm, they can be fed with special feed for yellow catfish. The best feeding method is to feed them in small amounts and multiple times. When they are first domesticated, they can be fed 3-4 times a day. After successful domestication, they can be fed 2-3 times a day.

5. Management

Patrol the pond every day, pay attention to the water color and the eating habits of the yellow catfish. If you find that the water quality or the appetite of the yellow catfish has decreased, find out the cause in time and take appropriate treatment measures to help the fry grow healthily.

When is the best time to feed yellow catfish?

The main conditions for breeding yellow croaker include ponds, water quality and feed. Among them, the pond is required to be built near the water source, and oxygenators or aerators must be prepared. Thorough disinfection is required before stocking. In addition, yellow croaker has relatively high requirements for water quality, and usually the water needs to be changed every half a month or so. Feed can be fresh animal feed or artificial compound feed, and it is required to be fed at a fixed time, fixed point, fixed quality and fixed quantity.

The profit of raising one acre of yellow catfish

Generally, the output of one mu of yellow croaker is about 4,000 catties. Its price is calculated according to the weight of the yellow croaker. Generally, the price of yellow croaker with a weight of about 5 taels is about 9 yuan per catty. Therefore, the output value of one mu of yellow croaker is about 36,000 yuan. Excluding the breeding cost, the net profit of yellow croaker breeding is more than 10,000 yuan.

Yellow catfish (Pelteobagrus fulvidraco) is a common freshwater fish in the family Pelteobagrus. The body is elongated and slightly stout, with the tip of the snout tilted upward toward the dorsal fin and flattened laterally at the back. The head is slightly large and flattened, with most of the dorsal part of the head exposed. The snout is blunt and rounded when viewed from the back. The mouth is large. The eyes are medium-sized. The nose barbel is located at the front edge of the posterior nostril, extending to or beyond the rear edge of the eye. The gill opening is large, extending forward to the ventral surface vertically below the middle of the eye. The dorsal fin is small, with bony thorns, and the front edge is smooth. The adipose fin is short, with the base located at the rear end of the dorsal fin base to the front of the center of the caudal fin base. The base of the anal fin is long, and the starting point is located vertically below the starting point of the adipose fin. The pectoral fin is laterally inferior, and the front edge of the bony thorns is fine and serrated. The pelvic fin is short, and the end extends to the anal fin. The distance between the anus and the starting point of the anal fin is about the same as that between the anus and the rear end of the pelvic fin base. The caudal fin is deeply forked and the end is round. The back of the living body is dark brown, and gradually becomes light yellow toward the abdomen. There is a narrow yellow vertical band above and below the lateral line, and a yellow horizontal band above the pelvic and anal fins, which intersect to form intermittent dark vertical patches. There is a dark vertical stripe in the middle of each lobe of the tail fin.

Pelteobagrus fulvidraco mostly lives in shallow waters around lakes with slow currents and abundant aquatic plants, as well as in rivers entering lakes. It lives a benthic life, and especially likes to live in shallows with still water or slow currents, and in places with a lot of humus and mud. It is omnivorous, and under natural conditions, it mainly feeds on animal feed. In the fry stage, it feeds on zooplankton, while adult fish feed on insects and their larvae, small fish and shrimp, snails and clams, and also swallows plant debris. It is distributed in Laos, Vietnam, China, North Korea, and southeastern Siberia, Russia. In China, it is distributed in the Pearl River, Minjiang River, Xiangjiang River, Yangtze River, Yellow River, Haihe River, Songhua River, and Heilongjiang River systems

Have you ever eaten yellow catfish? This is a very delicious freshwater fish with few bones, tender meat and rich fat. Although it is quite small, it tastes very delicious and is especially suitable for making soup. For example, it is very delicious when boiled with perilla, and a little pepper is sprinkled on it, which tastes good and can remove moisture. It is also super delicious when boiled with tofu and a little shrimp skin. And if you have a weak spleen and stomach, drinking such a soup is also very good for your stomach. Of course, don't forget pepper. Pepper and yellow catfish are not an ordinary match. Putting them together can enhance the deliciousness of yellow catfish.

The nutritional value of yellow catfish is much higher than other freshwater fish. Don't you want to try such a nutritious fish? Yellow catfish has been extremely popular in recent years and has become an economical breeding variety. If you want to breed very high-quality yellow catfish, it is not very easy. Next, let's talk about the difficulties in breeding yellow catfish and what breeding techniques are there.

1. What are the difficulties in breeding yellow catfish?

Although yellow catfish is an economical fish and seems to be easy to raise, it is not so easy to breed it. Let's take a look at the difficulties in breeding yellow catfish.

1. Tips for placing bait

I think many friends are very concerned about the issue of feeding. After all, feeding is very important for every kind of aquaculture, so I will talk about this difficulty in the front. So what should we pay attention to in the process of feeding? Because yellow catfish has different requirements for the nutrition of feed and the size of the bait in different breeding stages, so I think everyone needs to flexibly control the size of the bait and the amount of bait, otherwise it will easily cause waste of bait, which is a loss for everyone. And if you feed yellow catfish unreasonable bait, yellow catfish will also get sick. This is the skill of feeding bait, and yellow catfish also has requirements for the quality of bait.

2. Bait quality

The quality of bait directly affects the quality and yield of yellow catfish. However, the quality of yellow catfish bait on the market now varies from good to bad. This makes it very difficult for friends who are just starting to farm yellow catfish to choose. With more and more friends farming yellow catfish, the yield and density of yellow catfish are also increasing. Some large-scale yellow catfish farming bases can reach more than 30,000 per mu, and the output is about 5,000 catties per mu. Choosing high-quality yellow catfish bait is very important for farming yellow catfish. I think it is best to choose some large manufacturers with a good reputation when choosing yellow catfish bait. The bait of these manufacturers generally will not damage their own brand, and the quality should be quite good. In addition to the quality of the bait, water quality management is also very important for the farming of yellow catfish.

3. Water quality management

When more bait is put in, the content of harmful substances such as nitrite in the water body exceeds the standard. Therefore, in order to improve the water quality, we need to regularly add some biological agents to the pond to decompose the harmful substances in the water and increase the fertility of the water. If necessary, the bottom of the pond must be improved to reduce the content of harmful substances. I think you can also plant some aquatic plants such as water hyacinth in the water, which can purify the water quality and increase the bait for yellow catfish.

These are some of the difficulties we will encounter in the process of breeding yellow catfish. What are we going to look at next? Of course, it is the breeding method of yellow catfish. I hope everyone can breed high-yield yellow catfish.

2. Methods of breeding yellow catfish

The breeding of yellow catfish needs to follow certain steps, otherwise it is easy for yellow catfish to have problems. So what specific steps should we follow to breed yellow catfish? Let's take a closer look.

1. Build a pond

The first step in breeding yellow eels is of course to build a pond. What does this pond need to meet? I think this pond needs to have sufficient water sources, the water quality must be good, and drainage and water diversion must be very convenient. The silt in the pond should not be too thick, otherwise it will affect the water quality. The pond bottom with muddy texture is a very good choice. So what should the water level of the pond be controlled at? I think it should be above 1.2 meters, and fences must be set up at the drainage and water inlet of the pond to prevent the yellow catfish from escaping and prevent miscellaneous fish from entering the pond and affecting the growth of the yellow catfish. After transforming the pond, what is our next step? Of course, it is to release fish fry.

2. Fry selection

Before releasing the fry, you need to select the right fry. I think it is best to release the catfish in late February or early March. The temperature at this time is more suitable for the growth of catfish, and the density should be flexibly controlled according to the size of the pond. So what kind of fry is better? I think it is a very good choice to choose high-quality artificially bred fry. You can also raise some silver carp in the pond to purify the water quality and promote the growth of catfish. After releasing the fry, what is our daily feeding and management like?

3. Feeding and management

What kind of feed is better for yellow catfish? I think we should choose the puffed pellet type feed specially for yellow catfish, and it is best to make the protein content in the feed reach more than 45%, so that the feed is more suitable for the growth of yellow catfish. I think we need to feed yellow catfish twice a day, and the feeding time needs to be fixed, preferably around 8 o'clock in the morning and around 6 o'clock in the evening. We need to pay attention to it, because yellow catfish prefers to eat in the dark, so it is best to increase the feeding amount when feeding yellow catfish in the afternoon or at night, preferably 80% of the daily feeding amount, which can promote the growth of yellow catfish.

The above contents are the issues we need to pay attention to and the breeding methods of yellow catfish in the process of breeding yellow catfish. Are you clear about it? If you want to breed yellow catfish, you must pay attention to several difficulties, that is, the quality of yellow catfish feed and feeding skills. When feeding yellow catfish, you must pay attention to feeding according to the growth stage of yellow catfish, so that yellow catfish can absorb enough nutrition at each stage, and at the same time avoid feed waste.
