Yellow bonefish aquaculture technology and costs are as follows:

One, aquaculture technology

1, pond conditions

Yellow bonefish adult aquaculture ponds have certain requirements, ponds need to ensure that the depth of water in more than 1.5 meters to ensure that the area of 3 to 5 acres between the ponds are best to use a muddy sandy bottom, the pond should be Drainage and irrigation is convenient, sufficient water, need to pay attention to the fish species in the pond before using quicklime for pond disinfection.

2, the density of fish put

Yellow bonefish can be with other fish with feeding, set should be as large as possible to choose the yellow bonefish, about 10 cm, specifications for the 2-3cm yellow bonefish, 1800-2500 per acre of yellow bonefish, specifications for the 4-5cm yellow bonefish, 1500-1800 per acre of yellow bonefish.

3, feed feeding and management

Generally available small fish, shrimp, earthworms and other pure animal feed, available with feed, feed on protein, fat, vitamins have certain requirements.

Because the yellow bonefish is mainly carnivorous omnivorous fish, the protein content and quality of the feed requirements are higher, generally require protein content of 38%-40%. Already domesticated human-bred fry can be fed artificial feed directly, artificial compound feed needs to include fish meal, vegetable cake, soybean cake, secondary flour, rice husk bran, enticing and growth-promoting additives, and needs to be formulated with reference to the proportions of timed, quantitative, fixed, and qualitative.

4, daily management

The pond water of yellow croaker needs to be clean water and ensure its transparency should be maintained at 35-40 cm, because the yellow croaker's ability to tolerate low oxygen is poorer than that of the conventional fish, if the pond is stocked with high density, it should be set up with an oxygenator to prevent the floating head from lack of oxygen, yellow croaker like clean water, refill the water with new water regularly, and the water of yellow croaker should not be alkaline, and the dosage of quicklime used for preventing diseases should not be more than 20 g/_. The amount of lime used for disease prevention should not be more than 20 grams/_.

5. Fish disease control

If we can ensure the conditions of good water quality and sufficient feed, yellow croaker will grow rapidly, have good physique and not easy to develop diseases, and have certain inhibition and elimination effects on some crustacean parasites. The yellow croaker not only has a good resistance to disease, it can also eliminate other fish body surface susceptible to Anchovy, need to pay attention to the breeding process of yellow croaker on trichlorfon, cypermethrin and other pesticides are more sensitive, so yellow croaker ponds should not be used in the use of such pesticides.

Second, yellow bonefish farming costs

Fry can be fed about 5,000 per acre, the water surface rent is calculated on a yearly basis, but also need to bait, including small fish and shrimp, snail meat and so on. Drugs are mainly quicklime, need to be used once every half a month, 30 kg per acre, plus labor, water and electricity, transportation, aquaculture yellow bone fish need to invest in water surface rent, yellow bone fish fry, erbium, feed, drugs, labor and other costs, an acre a year to account for the cost of the words can be worth half a year's salary of the average urban workers.
