Problems solved by technology

[0005] But the above-mentioned control method can not be directly transferred to the prevention and treatment of amyloid dinoflagellate disease in the cultivation of yellow croaker. Therefore, in the artificial breeding process of yellow croaker, it has become an effective prevention and treatment of amyloid dinoflagellate disease. pressing issues

Embodiment Construction

[0017] Example 1, carried out in a certain breeding farm along the coast of Zhejiang Province, in order to prevent and cure the yellow croaker amyloid dinoflagellate disease, the following breeding methods were adopted:

[0018] 1. Prevention of dinoflagellates

[0019] 1. Bait control

[0020] In the process of artificial breeding, the frozen fish should be soaked in 30mg / L formalin for about 5 minutes before feeding. For the compound feed, for yellow croakers weighing 10-100 grams, the feeding amount is 5-8%; for yellow croakers weighing 100-300 grams, the feeding amount is 4-7%; For croaker, the feeding amount is 3-6%, and the baiting amount is the mass percentage of the compound feed and the weight of the croaker.

[0021] 2. Adjustment of breeding density

[0022] During the breeding process, different breeding densities are set according to the different body weights of croakers. The standard is: for croakers whose body weight is within the range of 10-100g, the stock...

Abstract

The invention provides a culturing method of nibea albiflora. The method comprises the following steps: treating frozen nibea albiflora in bait with formalin (20-50 mg/L) dipping bath for 4 to 6 minutes; controlling the feeding amount according to the weight of the nibea albiflora and controlling the culture density according to the weight of the nibea albiflora when mixed feed is used; performing regular medicated bath with seawater solution of mixture with the mass ratio of copper sulfate to ferrous sulfate of 7 to 3; reinforcing clean equipment, removing sludge at the bottom of a pool, and changing water to play the roles of killing amyloodinium ocellatum spores, removing pool water eutrophication generation conditions and eliminating a possibly existing amyloodinium ocellatum spreading source when the temperature of aquatic water exceeds 22 DEG C. Therefore, spreading of amyloodinium ocellatum is cut off, and propagation of the amyloodinium ocellatum is inhibited. Compared with the prior art, regarding the characteristics in nibea albiflora culture, the invention provides the culturing method of nibea albiflora capable of preventing occurrence and spreading of amyloodinium ocellatum disease, and the occurrence rate of the amyloodinium ocellatum disease is reduced to 20 percent of the previous occurrence rate after the method is used.

Description

technical field [0001] The invention relates to a method for cultivating yellow croakers, which belongs to the technical field of cultivating fish in agriculture, which is necessary for human life. Background technique [0002] Yellow croaker (Nibea albiflora), commonly known as yellow poke, belongs to the order Perciformes, the family Scrotoaceae, and the genus crocodile. It is a fish in the middle and lower waters of the coastal waters. It is mainly distributed in the coastal areas of China, the Korean Peninsula and the southern waters of Japan. Yellow croaker is delicious and nutritious, and is deeply loved by people. At present, in order to ensure the supply of yellow croaker in the market, large-scale artificial breeding and breeding have been carried out, and the disease caused by the parasitism of amyloid dinoflagellates is a main disease in the artificial culture of croaker. Amyloid dinoflagellate disease is a widely distributed and highly lethal fish disease. If it...
