Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fish farming, in particular to a method for breeding Trachinotus ovatus. BACKGROUND

[0002] Trachinotus ovatus is a marine fish, its scientific name is "ovate fin pompano", commonly known as gold pompano, yellow fin, etc., belonging to the order of Perciformes, the family of Carangidae and the genus of Trachinotus. The body length of Trachinotus ovatus is 18-74 cm, the body is oval, the body is high and the side is flat, the head, mouth and eyes are small, the body is covered with small and round scales, the anterior part of the lateral line is slightly curved, the first dorsal fin spine is short, the second dorsal fin is opposite to the anal fin, the anterior fin is long, the pectoral fin is wide and short, the abdominal fin is short and located behind the pectoral fin base, and the tail fin is bifurcated. The back of the body of Trachinotus ovatus is blue-gray, the abdomen is silver-white, and the edges of the odd fins are slightly gray. The meat is tender and delicious, and it is also a famous edible fish. Trachinotus ovatus is a warm-water and upper-layer migratory fish, lives in the tropic and temperate coastal waters, and the water depth is 50-200 meters. In China, it is mainly distributed in the South China Sea and the East China Sea, and occasionally found in the Yellow Sea.

[0003] Trachinotus ovatus grows rapidly and has strong disease resistance, and is welcomed by breeders. Although Trachinotus ovatus has strong disease resistance, due to the possible degradation of fish seed quality or the pollution of the breeding environment, many diseases occur in the process of breeding Trachinotus ovatus. For example, bacterial enteritis and ulcer disease. The pathogen of enteritis is enteric punctate aeromonas, which occurs all year round, and the peak period of epidemic is from April to October. The diseased fish swims alone, the fish body is black, the appetite is reduced, and even completely stops feeding. The local intestinal wall is congested and inflamed, and there is no food in the intestinal cavity. The intestinal mucosa is exfoliated, and the intestinal wall is exfoliated. There is a large amount of yellowish mucus in the intestine, the yellowish mucus flows out from the anus, and the anus is red and swollen. Sometimes the abdomen is swollen, and there is yellowish ascites in the abdominal cavity. The main pathogen of ulcer disease is bacteria, including Vibrio coralli, Pseudomonas aeruginosa and gram-negative bacillus. These bacteria are transmitted through water or contact between fish. It is caused by infection and inflammation of the surface and muscle of the fish, and often occurs in summer. It can occur on any part of the body surface of the diseased fish. After the disease, the fish body surface can be seen with block-shaped pustule sores, and the inside has pus, blood and bacteria. The scales are exfoliated and the muscle is rotten, the edge is congested and red, forming a circular or elliptical lesion. The fish is thin and weak, and the swimming is slow.

[0004] Diseases of Trachinotus ovatus occur throughout the process of breeding Trachinotus ovatus, and are also the most important cause of death in the process of breeding Trachinotus ovatus. If not handled properly, it often leads to low survival rate and slow growth, which is a very important factor affecting economic benefits. Therefore, it is necessary to prevent diseases, clarify the pathogenesis, and scientifically, efficiently and environmentally treat various fish diseases of Trachinotus ovatus. SUMMARY
