CATDOLL : CATDOLL: What are the techniques for breeding steel loach? Is the steel loach a protected fish?

1. What is the technology of breeding steel loach?

1. Stocking of loach fry

Before stocking, you need to select the seedlings, try to stock the seedlings that are healthy, disease-free, strong and energetic. The size of the loach in each pond should be roughly the same, which is convenient for future management. Before stocking, the seedlings must be washed and disinfected. You can use low-concentration salt water to soak for 5-10 minutes. The general density is about 2-3 kilograms per square meter. As the stocking amount increases and the weight increases, the pond water can be deepened to 50-70 centimeters.

2. Usage

Half a month after the loach seedlings were released, they were mainly fed with natural bait, and some fish meal, bean cake and bait were appropriately supplemented. The daily feeding amount accounted for 2% of their body weight. When the loach grew to 5 cm in summer, they were fed with complete compound feed. The feeding amount should not be too much, and it is better for the loach to eat it within 2 hours. The feeding should be placed near the feeding table.

3. Water quality regulation

The water quality for loach breeding is yellow-green in color, with transparency maintained between 20-25 cm and pH value at around 7.5. The water level is maintained above 80 cm in July and August. Once the water color is too dark, the water must be changed in time. Generally, 1-2 feet of water is changed every 10 days, and about one-third of the water is changed each time.

4. Management

In winter or early spring, the straw covering the loach breeding greenhouse should be removed from the plastic shed between 10 am and 3 pm on sunny days. The straw can be used to cover the shed for heat preservation at other times. In summer, the plastic film of the greenhouse should be removed, and aquatic plants can be planted in the pond to provide shade. In autumn and late spring, the film should be improved and covered with straw at night.

2. Is the stone loach a protected fish?

no.

The stone loach is often called knife loach, knife loach, stone cone, thorn loach or knife cut by the people. This is because this fish looks very much like loach, but it is a more dangerous fish than loach. Because it has its own "weapon".

Because the steel loach has very high requirements for water quality, this fish can only survive in running water and waters that are not polluted. Once the water is polluted, it basically cannot survive. In addition, many people have been overfishing in the past few years, using unscientific fishing methods, especially the serious situation of electrofishing, which has led to the disappearance of steel loach in many places.

4. Red-tailed steel loach farming?

Family Loach Farming

1. Dig a pond in the courtyard to raise loaches; Families with conditions. You can dig a fish pond or place a water tank in front of or behind the house or in the courtyard to raise loaches. Put a layer of soil at the bottom of the breeding pond or water tank to allow loaches to burrow and live. Keep the water depth at about 50 cm. Stock 1 kg of young loaches per square meter. During the breeding process, you can feed them with animal baits such as vegetable leaves, water plants, rice, bran, bean cakes, vegetable cakes, silkworms, animal waste, silkworm pupa powder, fish meal, etc. If conditions permit, it is best to make a mixed bait and stir it into blocks for feeding. When breeding adult loaches, it is not advisable to feed too much animal bait, because loaches will not be able to digest it easily if they eat too much.

Family breeding can also be self-breeding and self-feeding. In the breeding season, as long as there is a small amount of water flow stimulation in the small water body where it is raised, loaches can lay eggs and reproduce, and hatch into juvenile loaches and adult loaches.

2. Raising loaches in wooden boxes

① The specifications of the wooden box structure for raising loaches are 23 meters in length, 11.5 meters in width, and 0.8 meters in height. The inner wall is required to be smooth, and a 3-centimeter-diameter filling and drainage port should be opened on one or two sides of the box. Wire mesh should be installed at the filling and drainage port and the box cover.

② Fertilization and stocking Pile soil and chopped straw or compost in the box (about 3 kg per box), and inject warm water to a depth of centimeters above the soil layer. Bury several interconnected water pipes in the soil in the box to ensure injection and drainage. Inject about 1.85 liters of water into each box. After 35 days, release about 100 loaches per square meter. It is best to disinfect the fish before stocking.

③ Careful feeding Feed includes rice bran, snails, silkworm pupae, fish viscera, etc. Feed twice a day, at 67 in the morning and 1 in the afternoon. The daily feeding amount is 78% of the loach's body weight. It can be increased or decreased according to the loach's eating habits. The maximum feeding amount can reach 15% of the fish's body weight. Stir the lower layer of mud once every 10 days to facilitate the growth of the loach's natural bait. After feeding from April to November, the loach can gain 8-10 times its weight.

④ Daily management Since the density of wooden box breeding is high, water quality management is very important. Remove the leftover bait every day, and observe the loach's eating and activities frequently. If the loach shows abnormal phenomena such as frequent intestinal breathing and sudden stop eating, the water should be changed immediately. Generally, the water should be changed once every 10 days (after changing the water, appropriate topdressing can be done). If sick loaches or dead loaches are found, they should be removed in time to prevent the spread of fish diseases. In the later stage of breeding, new water should be added appropriately or loaches that have reached the market specifications should be removed to reduce the density and promote growth.

5. Red-tailed steel loach breeding technology?

1. If you want to raise red-tailed loach artificially, you should choose to use a fish tank. It is best to have a larger fish tank so that it is easier to raise and the red-tailed loach can have a larger range of activities.

2. In the fish tank for breeding red-tailed steel loach, some mud and sand need to be put at the bottom, so that the red-tailed steel loach can be better bred. This must be done well.

3. During the breeding period of red-tailed steel loach, you must pay attention to the water. Generally, if it is bred with tap water, the tap water must be left to stand for a period of time before the red-tailed steel loach can be raised.

4. When feeding red-tailed loach, you can choose to use bloodworms. Don’t feed too much. Generally, 1-2 times a day is enough.

5. During the breeding period of red-tailed steel loach, you must pay attention to changing the water. Generally, you should change the water once a month to avoid water deterioration. This requires special attention.

6. During the breeding period, red-tailed loach should not be raised together with other fish. This needs attention. Otherwise, it is normal for fish to eat each other.

7. What should be fed to red-tailed loach?

A certain amount of artificial feed should be fed every day. The types of feed include fish meal, pig blood meal, silkworm pupa meal, rice bran, wheat bran, vegetable cake, etc. The feeding amount can vary according to different seasons. In May and June, it is 4% to 5% of the loach's body weight; in July and August, it is 8% to 10%; in September and October, it is 5% to 6%. A feeding table should be set up in the pond, and the bait should be thrown on the feeding table. Each pond can have 3 to 4 feeding tables according to the size. Generally, the bait should be eaten within 2 to 4 hours after being thrown. The feeding table should be cleaned every 3 to 5 days to prevent diseases. The pond should be frequently filled with new water to maintain a good water quality environment.

8. Is there a future in breeding red-tailed steel loach?

Promising

The main reason is that the environment in which it lives is flowing water with sufficient oxygen. Although it is possible to simulate such an environment through artificial breeding, it is not a wild environment after all, and it is difficult for the steel loach to adapt, and the cost of domestication is not low. Currently, there are not many people breeding steel loaches, and the market is still dominated by wild ones.

The steel loach is a high-end product. Because it lives in clear water, it has almost no earthy smell and its meat is also very good. Nowadays, it is also sold at a high price, almost 100 yuan per pound. Of course, its price is so high because there are few artificial breedings and the number is small, so it is sold at a high price.

9. How to catch steel loach?

The locals use bamboo chopsticks to catch this kind of fish. They first use the chopsticks to clamp the earthworm, and then gently place the loach in the water and wait for the fish to eat it. When the stone loach swims over, they clamp the fish.

10. How to breed knife loach?

The artificial breeding technology of knife loach is as follows:

1. Pond culture: For pond culture of loach, cement pond or cement pond is generally used, with a depth of 70-100 cm, a water depth of 50-60 cm, and a 15-20 cm thick layer of fertilizer mud on the bottom of the pond. The area of ​​the pond can be large or small, and 2-3 mu is preferred. The pond should be easy to drain and irrigate, and the inlet and outlet should be equipped with wire mesh to prevent escape. The pond should be cleaned and disinfected before stocking, and the method and dosage are the same as those for the fry pond.

2. Pond polyculture is polyculture with other fishes, such as silver carp, bighead carp, carp, grass carp, bream, etc. The selection, cleaning, disinfection and stocking of this type of culture are the same as those of pond culture.

The advantage of mixed breeding is that it is not necessary to feed loaches with more bait, but only other fish. The uneaten bait and feces of fish are the food source of loaches. Therefore, this breeding method is highly efficient and has great water surface utilization value, which is worth promoting.

3. Rice field breeding: my country's southern rice-growing areas are vast. Raising loaches in rice fields not only saves water but also obtains food. It has significant economic benefits and is a good breeding model for efficient agriculture.

3.1. Rice field selection. The best rice fields for breeding loaches are those that are slightly acidic, less silt, have good water retention, and do not overflow during rainfall. High ridges should be built around the rice fields. Two nets should be set at the inlet and outlet to prevent loaches from escaping.

3.2. Stocking and management. Seedlings are placed after the early or mid-season rice is planted. Generally, 40,000 to 50,000 loaches are placed per mu. Before stocking, organic fertilizers should also be applied to cultivate floating plants and animals in the water.

3.3. Use as little pesticide as possible or no pesticide at all in rice fields where loaches are raised. Even if pesticides are needed, they should be applied in batches and the nozzles should be pointed upwards. Do not spray the liquid on the water surface. In addition, do not use herbicides. When planting double-season late rice, it is best to use the no-till method to avoid mechanical damage to loaches.

4. Pond farming.

This method of breeding is to use small fertile ponds in front of or behind houses to raise loaches. The area of ​​the pond can be large or small, ranging from a dozen square meters to forty or fifty square meters. Conventional fish will die of hypoxia in such ponds due to excessive organic matter and insufficient dissolved oxygen. Loaches grow well in such ponds because they have special respiratory organs.
