Problems solved by technology

[0003] At present, yellow croaker mainly depends on the fishing output of natural waters. With the continuous increase of market demand and the continuous reduction of natural resources, the fishing output in natural seas can no longer meet the needs, and it is urgent to carry out artificial breeding of yellow croaker

Embodiment 1

[0020] Select the sandy soil pond for use, with an area of ​​about 2 mu. Referring to the accompanying drawings, half of the bottom of the pond is a slope, and the slope is preferably 30-40°. One end of the bottom of the pond is provided with an inlet pipe 2, and the other end is provided with an outlet pipe 1. One end in the pond of water pipe 2 and outlet pipe 1 is covered with protective net 3 to prevent croaker from escaping; the shallowest part of the pond is 1m and the deepest is 3m, and the salinity of pond water is about 18%; a retractable greenhouse is set at the pond. By adjusting the retractable greenhouse to cover or expose the pond, the water temperature can be adjusted to keep the water temperature at 12-25°C.

[0021] Around May, when the natural water temperature reaches 15°C, fish fry can be put in. Disinfect and fertilize the pond 9 days before putting it in. The method in the prior art can be used for disinfection; after disinfection, fertilize the pond when ...

Embodiment 2

[0028] Different from Example 1, the area of ​​the earthen pond in this example is 5 mu, the shallowest part of the pond is 0.8m, the deepest part is 3.5m, and the salinity is about 16%. The stocking density is 11,000 tails / mu.

Embodiment 3

[0030] Different from Example 1, the area of ​​the earthen pond in this example is 1 mu, the shallowest part of the pond is 0.5m, the deepest part is 2.5m, and the salinity is about 28%. The stocking density is 8000 tails / mu.

Abstract

The invention discloses a cultivation method for spotted maigre. An artificial pond is adopted for feed, the salinity of the pond is 16 to 28 per thousand and the temperature thereof is 12 to 25 DEG C; the body length of stocking fish fry is 3 to 5cm, the stocking density is 8000 to 11000 fishes per mou; bird-peck foods are selected and used as the feed; the bottom of the pond is a slant plane; the shallowest point of the pond water is 0.5 to 1.5m and the deepest point thereof is 2.5 to 3.5m; a telescopic tent is arranged beside the pond, the cover of the tent is adjusted or the pond is exposed to regulate water; the feed is thrown into the pond twice a day, the thrown feed amount per day accounts for 10 to 20 percent of the body weight of fish; By using the method of the invention, the artificial cultivation for spotted maigre can be realized and market requirements are met.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a method for cultivating yellow croakers. Background technique [0002] Yellow croaker, also known as yellow croaker (Nibea albiflora), is a member of the Osteostylidae family of Osteichthyes. It is mainly produced in the East China Sea and Bohai Sea in my country. Its appearance is similar to that of large yellow croaker, with elongated body, flat sides, blunt pointed head, short blunt snout, Slightly protruding, without whiskers and canine teeth, the upper teeth are small, the inner teeth of the lower jaw are larger, and there are 5 small holes in the skull. The back of the body is light gray, the sides are light yellow, the base of the chest, abdomen and anal fin are reddish, there are many dark brown wavy fine lines obliquely forward, and the caudal fin is wedge-shaped. It is a warm-temperate near-bottom fish. Its meat contains 19.3 grams of protein and 3.2 grams of fat per 100 gram...
