Problems solved by technology

However, during the grouper breeding process, the ammonia nitrogen content in the water increases, the dissolved oxygen decreases, and harmful bacteria grow in large numbers. The grouper is prone to disease, and the survival rate is reduced. The surviving grouper is also in a sub-healthy state, and the meat quality is low. , low nutritional value

Embodiment 1

[0020] A culture method for grouper, comprising the following steps:

[0021] 1) Preparation before stocking: Before stocking fish species, thoroughly clean and disinfect the pond, after cleaning the pond, apply decomposed fermented manure, and fill the pond with water;

[0022] 2) Put fry: put grouper fry into the pond, control the dissolved oxygen in the water, and monitor the ammonia nitrogen content in the water;

[0023] 3) Transformation and domestication: first feed the fry with water earthworm slurry, rotifers and surimi, gradually increase the amount of crude protein, and finally feed them with feed;

[0024] 4) Daily management: Replace new water on schedule, monitor the ammonia nitrogen content and dissolved oxygen in the water, inject microbial preparations in due course, and feed feed in batches every day.

[0025] The microbial preparation components and their weight parts are 30-50 parts of Rhodopseudomonas palustris, 10-20 parts of Bacillus cereus, 30-35 parts...

Abstract

The invention discloses a culturing method for epinephelus coioides. The culturing method comprises steps of 1) preparation before releasing, 2) releasing seedlings, 3) changing food and domestication, and 4) daily management. The beneficial effects are that according to physiological characteristics, a culturing environment condition is controlled; according to growth and development conditions of an Epinephelus coioides digestion system, food is changed slowly and the Epinephelus coioides are domesticated; the Epinephelus coioides have fast growth speed and vigorous vitality; ammonia nitrogen organic matters in water can work as nitrogen source and carbon sources by microorganism agents; the Epinephelus coioides can be biochemically dissolved; beneficial bacteria flora largely propagate to form advanced flora, and poisonous bacteria breeding in water can be prevented; catechol and phenol in water can be removed; flocculation effect can be achieved; and water quality clarity can be improved.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a method for cultivating the grouper. Background technique [0002] The grouper belongs to the order Perciformes, and the body is oblong and slightly flattened. The mouth is large, with an auxiliary maxilla, and the teeth are fine and pointed, and some expand into canine teeth. The body is covered with small ctenoid scales, sometimes buried under the skin. The dorsal and anal fins have developed spines, the caudal fin is round or concave, and the body color varies a lot, often brown or red, with stripes and spots. It is a large and medium-sized marine fish in warm water. There are 12 species of grouper distributed along the coast of Fujian, among which the more common species with higher economic value are red-spotted grouper, salmon-spotted grouper, cloud-spotted grouper and net-spotted grouper. Red-spotted grouper and clouded grouper. Blue grouper is also known as green grouper ...
