CATDOLL : CATDOLL: How many kilograms of loach can be produced per mu?

1. How many kilograms of loach can be produced per mu?

The standard practice is to "put 100 kg of seedlings per mu". At the time of harvest, "500 kg of loaches will be harvested based on the yield multiplied by 5, and they can be sold for 15,000 yuan after November and during the Spring Festival". If the costs are excluded, including 4,400 yuan for 100 kg of seedlings, about 4,000 yuan for feed, 100 yuan for medicine, 300 to 500 yuan for escape prevention nets (replaced once every three years), and about 200 yuan for trenching in the rice field (this cost is only incurred in the first year). In the first year of release, the net income from loaches in one mu of rice field can reach 5,800 yuan. In the second and third years, the net income is expected to reach more than 6,500 yuan.

The seedlings are 2 to 3 cm small loaches, which cost about 500 yuan per 10,000. One acre of land is used to stock 100,000 to 150,000 loaches, which means 5,000 to 7,500 yuan for seedlings. In addition to feed disinfection and medicines, it will cost about 3,000 to 3,500 yuan per acre. I said that under normal circumstances, if nothing unexpected happens, that is, if the loaches do not get sick or escape. When harvested, it will be between 1,500 and 2,000 kilograms. The market price of loaches varies from place to place. It is cheap in summer and expensive at the end of the year. Haha, it depends on the market price where you are. Ours is 7 to 10 yuan in summer and 16 to 20 yuan at the end of the year. So you should have calculated it clearly. In addition, it is cheaper to buy small-sized seedlings when buying seedlings. The small size of 0.7 cm is 150 yuan per 10,000 loaches, but the feed is also expensive. It is recommended to buy large-sized loach seedlings for initial breeding. . I would also like to give you a piece of advice. When it comes to breeding, you have to be professional and diligent. You should check more often and ask more experienced people for advice. Loaches are relatively easy to raise. At least in a pond, even if the fish die, the loaches are still alive. Don't worry too much. Only when ideas are turned into reality can there be a chance of success.

2. What is the yield per mu of loach cultured in ponds?

Loach is one of the important aquaculture species because of its strong adaptability, few diseases, high survival rate, strong reproductive capacity, convenient transportation and easy availability of bait. If it is cultured in cages, take one acre of cage cultured loach as an example:

1. A 6-square-meter cage costs 60 yuan, 50 cages can be set up in one acre, and the cost of the cage is 3,000 yuan (it can be used for about three years);

2. One mu of net cage can be used to put 1,000 jin of seedlings, with a specification of about 10 grams. 3 jin is put per square meter. The purchase price of seedlings is about 8 to 10 yuan/jin. 10 yuan/jin x 1,000 jin (seedlings) = 10,000 yuan (loach is easier to catch in spring and summer, and the price is slightly lower);

3. The drug cost for a 6-square-meter cage is 12 yuan; the drug cost for one acre is 600 yuan.

4. The feed for a 6-square-meter cage costs 240 yuan, and the feeding cost for each kilogram of loach weight gain is 4 yuan, so the feed cost for one acre is 12,000 yuan (in fact, using a large amount of earthworms as feed can reduce the cost by 20%).

A 6-square-meter cage needs to be stocked with 20 jin of seedlings. After 4-6 months, the weight of loaches increases by about 4-6 times, a total of 80 jin. The annual output of one mu is more than 4,000 jin. According to the market price of about 12-15 yuan per jin in autumn and winter (if it is put on the market before the Spring Festival, the price will be higher), the income of one mu of cage is 48,000 yuan.

3. How many kilograms of Taiwan loach can be produced per acre

This depends on the type of breeding you use, such as cement pool monoculture, pond polyculture, rice field breeding, etc. Among them, cement pool monoculture is relatively large in stocking volume, with about 30,000 5cm~8cm seedlings per acre being moderate. After 8 months of breeding, the high yield can reach 250-400 kg per acre.

1. Build a pond: Build a pond in front of or behind the house, around the courtyard, in a place with water source, sheltered from the wind and facing the sun. The pond is usually made of bricks and stones, and the depth of the pond should be about 1 meter. After the pond is built, it is smoothed with cement, and after it is dry, 0.5 feet of fertilizer mud is added, and 1 foot of clean water is injected, and then the seeds can be planted.

2. Stocking: After the pond is built, stock the loach fry at a rate of 1-1.5 catties per square meter. Female loaches have a strong spawning capacity, and a female loach can produce more than 4,000 eggs from early summer to early autumn. Generally, it produces 2-3 times a year, with more than 10,000 eggs.

3. Feeding: Since loach is an omnivorous fish, cow dung, rice bran, wheat, or fly maggots can be used as bait. Generally, three times a day is enough. The feeding amount is generally determined by the feeding situation.

4. Fertilization: During the feeding process of loach, you can add some organic fertilizer appropriately, but do not apply too much or too frequently, and change the pond water frequently, generally once every 10-15 days.

5. Capture: To capture loaches, you must first drain the pond water and adopt the method of catching the big ones and leaving the small ones to ensure that there are a certain number of loach fry in the pond, which is conducive to continued breeding and high yield.

4. How many kilograms of Taiwanese loach can be produced per acre?

Two batches of Taiwan loach can be raised a year, and one batch of fry can produce about 3,000 kilograms per acre of land.

Taiwan loach, also known as large-scale paraloach, belongs to the order Cypriniformes, family Cobitidae, genus Paraloach. Distributed in Sichuan, Zhejiang, Taiwan, Liaoning, Heilongjiang, etc. The body is nearly cylindrical, with a short head. The mouth is inferior and horseshoe-shaped. There is a small notch in the center of the lower lip. The nostrils are close to the eyes. There are no spines under the eyes. The gill openings are small. The head is scaleless, and the body scales are larger than those of loach. The lateral line is complete. There are 5 pairs of whiskers. The eyes are covered with membranes. The skin folds at the caudal peduncle are well developed and connected to the caudal fin. The length and height of the caudal peduncle are approximately equal. The caudal fin is round. The anus is close to the starting point of the anal fin. The back and upper half of the body are gray-brown, and the belly is white. There are many irregular black-brown spots on the sides of the body. The dorsal and caudal fins have small black spots, and the other fins are gray-white.
