example 1

[0020] The invention provides a technical solution: a three-dimensional cultivation method of large yellow croaker, the production steps include the following: S1, select fish species: select fish species with uniform individuals, no disease, no injury, no deformity and strong mobility, and put them into the breeding Fill the breeding box with seawater, and add fresh water in an appropriate amount according to the pH value; S2, feeding feed: prepare feed in proportion, using 20 parts of small miscellaneous fish, 10 parts of earthworms, 20 parts of shrimp and crab shells, and 5 parts of vitamin C 6 servings of yellow powder, once a day in the morning and once in the evening, the feed amount is 8% of the fish's body weight; S3, oxygenation: fill the breeding box with oxygen regularly every afternoon, and the time to turn on the aerator is controlled at 2-4h ; S4, water purification and circulating salt filtration: Use the connecting hose at one end of the water pump to connect to...

example 2

[0026] The invention provides a technical solution: a three-dimensional cultivation method of large yellow croaker, the production steps include the following: S1, select fish species: select fish species with uniform individuals, no disease, no injury, no deformity and strong mobility, and put them into the breeding Fill the breeding box with seawater, and add fresh water in an appropriate amount according to the pH value; S2, feeding feed: prepare feed in proportion, using 30 parts of small miscellaneous fish, 20 parts of earthworms, 15 parts of shrimp and crab shells, and 1 part of vitamin C 2 portions of yellow powder, once a day in the morning and once in the evening, the feed amount is 8% of the fish's body weight; S3, oxygenation: fill the breeding box with oxygen regularly every afternoon, and the time to turn on the aerator is controlled at 2-4h ; S4, water purification and circulating salt filtration: Use the connecting hose at one end of the water pump to connect to ...

Embodiment 1

[0031] Embodiment 1 improves the feed nutrient content of large yellow croaker by increasing the fraction of small miscellaneous fish, earthworms and shrimp and crab shells, promotes growth, and improves the survival rate of fry. Embodiment 2 prevents diseases by increasing 1 part of vitamin C and 2 parts of yellow powder Occurs, effectively prevents diseases from occurring, and emits harmful gases in the water.

[0032]To sum up, the three-dimensional breeding method of large yellow croaker is connected to the breeding box through the set water pump, which can purify the water quality, promote the normal growth of large yellow croaker, improve the quality of breeding, help improve the survival rate of fry, and prevent the occurrence of diseases , to effectively prevent the occurrence of diseases, to emit harmful gases in the water, and through the set aerator, fresh oxygen can be dissolved to promote the growth of fish.

Abstract

The invention discloses a three-dimensional culture method of pseudosciaena crocea. The method comprises the following steps that S1, fingerlings are selected, wherein the fingerlings with uniform individuals, no disease, no injury, no deformity and strong activity are selected to be put into a culture box, seawater is filled into the culture box, and a proper amount of fresh water is added according to the pH value; S2, feed is put and is prepared in proportion, 20-30 parts of small trash fishes, 10-20 parts of earthworms, 15-30 parts of shrimp and crab shells, 1-5 parts of vitamin C and 2-6parts of yellow powder are adopted, the feed is fed once in the morning and once at night every day, and the feeding amount of the feed is 8% of the weight of the fishes; S3, oxygen filling is carriedout, wherein the culture box is filled with oxygen at regular time every afternoon, and the time for starting an aerator is controlled to be 2-4 hours; and S4, water purification and circular salt filter are carried out, wherein a connecting hose at one end of a water pump is connected into the culture box to pump water, an output hose at the other end of the water pump is placed in the culture box, the purifying and salt filtering time is controlled to be 2 h / day to 5 h / day, normal growth of pseudosciaena crocea can be promoted, the culture quality is improved, and the survival rate of fry is increased.

Description

technical field [0001] The invention relates to the technical field of large yellow croaker cultivation, in particular to a three-dimensional cultivation method of large yellow croaker. Background technique [0002] Large yellow croaker is a fish belonging to the family Stoaceae and the genus Yellow croaker. Body elongated, laterally flattened, with multiple rows of luminescent particles on the ventral side of the body; head blunt and pointed. Mouth large, end-positioned, oblique, snout not protruding, upper jaw equal to lower jaw, posterior edge of maxilla reaching posterior edge of orbit; inner teeth of mandibular teeth larger, outer teeth close to inner teeth; 4 or 6 mental foramina , the central 4 holes are arranged in a square around the Yi suture, and the first 2 holes are small. There are 2 nostrils, the oblong posterior nostril is larger than the circular anterior nostril. The lower edge of the orbit extends to the level of the top of the premaxilla. The rear edg...
