Yellow bone fish culture technology and cost, regular injection of new water

Pond conditions: the water depth is more than 1.5m and the area is about 3-5 mu, which needs to be disinfected with limestone before release. Release density: according to the body length of fish species, it is generally about 2000 fish per mu. Feed feeding: can feed small miscellaneous fish, earthworms and other animal feed, with fish meal, vegetable cakes and other artificial feed. Daily management: to maintain the cleanliness of water, high-density culture needs to be equipped with aerator. Culture cost: the annual cost of raising one mu of yellow bone fish is about 25000 yuan.

I. Culture techniques of yellow bone fish

1. Pond conditions

The main results are as follows: (1) the adult culture of yellow bone fish has certain requirements for the pond, and the pond needs to ensure that the water depth is more than 1.5 meters.

(2) to ensure that the area is between 3 and 5 mu, the pond had better use silt bottom.

(3) the pond should have convenient drainage and irrigation and sufficient water.

(4) it is necessary to pay attention to cleaning and disinfecting the pond with quicklime before the fish species go into the pond.

2. Fish release density

Yellow bone fish can be fed with other fish, when captive culture should choose a larger size of yellow bone fish, about 10 centimeters.

The size of 2-3cm yellow bone fish is 1800-2500 per mu.

For yellow bone fish with a specification of 4-5cm, 1500-1800 fish are put in per mu.

3. Feed feeding and management

(1) Pure animal feed such as small miscellaneous fish, shrimp, earthworms, etc.

(2) available formula feed, which has certain requirements for protein, fat and vitamins.

(3) as the yellow bone fish is an omnivorous fish mainly carnivorous, the protein content and quality of the feed are required to be 38% and 40%.

(4) the breeding seedlings that have been domesticated can be fed with artificial feed directly, and the artificial compound feed should include fish meal, vegetable cake, bean cake, secondary powder, rice skin bran, food induction and growth promoting additive, and the proportion formula of timing, quantity, fixed point and quality should be referred to.

4. Daily management

(1) the pond water for culturing yellow bone fish needs to be clean water and its transparency should be kept at 35-40 cm.

(2) as the hypoxia tolerance of yellow bone fish is worse than that of conventional fish, an aerator should be set up to prevent anoxic floating head if the stocking density in the pond is high.

(3) Yellow bone fish like clean water and add new water regularly.

(4) the water of yellow bone fish pond should not be too alkaline, and the amount of quicklime used for disease prevention should not exceed 20 g / kg.

5. Prevention and treatment of fish diseases

The main results are as follows: (1) if the conditions of good water quality and adequate feed can be guaranteed, the yellow bone fish will grow rapidly, have a good physique and are not easy to get sick. It also has a certain inhibition and eradication effect on some crustacean parasites.

(2) the yellow bone fish not only has good disease resistance, but also can eliminate the Anchor head disease on the body surface of other fish.

(3) it is necessary to pay attention to the sensitivity of yellow-bone fish to pesticides such as trichlorfon and deltamethrin, so these pesticides should not be used in ponds with yellow-bone fish.

Second, the culture cost of yellow bone fish.

1. Fish fry: 0.30 yuan per tail, about 5000 fry can be fed per mu, a total of 1500 yuan.

2. Water rent: 600 yuan / mu / year.

3. The bait includes small fish, shrimp, snail meat and so on: 1.5 yuan / kg, the average feed coefficient is 30, and the food cost per kilogram gain is 45 yuan. If you choose compound feed, the unit price is 7 yuan / kg, and the feed coefficient is about 1.3. if you calculate according to the yield of 3000 jin of fish per mu, it will cost about 22000 yuan.

4. The medicine is mainly used for living lime, which needs to be used once every half a month, 30 kilograms per mu, and about 210 yuan if the breeding period is 7 months.

5. The cost of labor, water and electricity, transportation and so on is about 1000 yuan per mu.

To sum up, the cultivation of yellow-bone fish needs to invest in surface rent, yellow-bone fish fry, erbium feed, feed, medicine, labor and other expenses, and if the cost is calculated per mu a year, it will cost about 25310 yuan per mu.
