Three-dimensional culture method of pseudosciaena crocea

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...

Problems solved by technology

[0003] The existing three-dimensional culture method of large yellow croaker cannot purify the water quality, which will cause the water quality to become dirty and polluted for a long time, affect the normal growth of large yellow croaker, reduce the quality of the culture, and the survival rate is low, which may also cause diseases and cannot dissolve in fresh oxygen , fish grow slowly,
