Problems solved by technology

If it is not timely and accurately diagnosed and effective prevention and control measures are taken, cryptocystosis stimulated by golden fish will spread to a large area and break out rapidly in a short period of time, which will be devastating to golden fish farming, with a mortality rate as high as 100%.
In recent years, coastal money fish farming has been repeatedly infested by Cryptocaryonia stimuli, causing heavy losses and affecting the healthy and sustainable development of the aquaculture industry. At present, there is no specific drug for preventing and treating the disease of Cryptocaryon stimuli, and it is operable and easy to master. utility method

Embodiment 1

[0023] a. Nutrient-intensive cultivation: During the breeding period, fish juvenile fish with a body length of more than 10 mm were caught from the sea area, and the juvenile fish fry with a body length of more than 10 mm had completed the metamorphosis period. Then the juvenile golden fish fry are cultivated in the sandy mud pond with a suitable density of seawater biological bait in advance, and the biological density of the seawater biological bait in the pond is kept at 5 / ml to 10 / ml, and the supplementary feeding is easy to digest Absorbed soft compound feed, such as eel compound feed, the daily feeding amount of this soft compound feed is 3% of the total mass of fish, gradually transition to feeding extruded seawater fish compound feed, the daily feeding amount of extruded seawater fish compound feed 5% of the total mass of fish. The survival rate of the juvenile fish with a body length of 5 cm is as high as 95% after intensive cultivation in ponds. The juvenile fish se...

Embodiment 2

[0026] a. Nutrient-intensive cultivation: During the breeding period, fish juvenile fish with a body length of more than 10 mm were caught from the sea area, and the juvenile fish fry with a body length of more than 10 mm had completed the metamorphosis period. Then, the juvenile goldfish fry are intensively cultivated in a sandy mud bottom pond with a suitable density of seawater biological bait in advance, and the biological density of the pond bait is kept at 5 / ml to 10 / ml, and supplementary feeding is easy to digest and absorb. Soft compound feed, such as eel compound feed, the daily feeding amount of this soft compound feed is 4% of the total mass of fish, gradually transition to feeding extruded seawater fish compound feed, and the daily feeding amount of extruded seawater fish compound feed is 6% of the total mass. The survival rate of larvae larvae grown to a body length of 5 cm after intensive cultivation in ponds reached 96%. The juvenile fish seedlings with a body ...

Embodiment 3

[0029] a. Nutrient-intensive cultivation: During the breeding period, fish juvenile fish with a body length of more than 10 mm were caught from the sea area, and the juvenile fish fry with a body length of more than 10 mm had completed the metamorphosis period. Then the money fish seedlings are cultured intensively in sandy mud bottom ponds with seawater biological bait of suitable density in advance, and the biological density of the pond bait is kept at 5 / ml-10 / ml, supplemented with soft and easy to digest and absorb. Sexual compound feed, such as eel compound feed, the daily feeding amount of this soft compound feed is 5% of the total fish mass, and gradually transition to feeding extruded seawater fish compound feed, the daily feeding amount of extruded seawater fish compound feed is 5% of the total fish mass. 7% of mass. The survival rate of the juvenile fish of the golden fish, which grows to a body length of 5 cm after intensive cultivation in the pond, reaches 96%. Th...

Abstract

The invention discloses a prevention and control method for cryptocaryon irritans of scatophagus argus. According to physiological and ecological features of the scatophagus argus, the purpose of preventing and controlling the cryptocaryon irritans of the scatophagus argus is met with a combined method of nutrient enrichment cultivation and disease prevention of the scatophagus argus, drug therapy of the cryptocaryon irritans and ecological regulation, wherein therapeutic drugs are copper acetate and zeolite powder combined with copper acetate, furacilin antibiotics or an algae-inhibitory compound and furacilin antibiotics combined with the algae-inhibitory compound. The survival rate of the young scatophagus argus intensively cultivated with the method is greatly increased and reaches more than 95%; the fry survival rate of the diseased scatophagus argus is increased from 0% to 64-88%, so that the economical loss is greatly reduced. The method is remarkable and stable in effect and easy to master, popularize and apply, has the characteristics of economy, good actual effect, low toxicity, easiness for operation and the like, and has an important actual effect for establishing a technical system for disease prevention and control of the scatophagus argus and promoting the development of the breeding industry of the scatophagus argus.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for preventing and treating cryptocytoniasis stimulated by money fish. Background technique [0002] The money fish (Scatophagus argus) has a beautiful and strong body, colorful colors, docile temperament, delicious meat and rich nutrition. It is a rare seawater economic fish with ornamental and edible value. In my country, it is mainly distributed in the South China Sea, the Taiwan Strait, and the coastal rocky reefs of the East China Sea, seaweed clusters, and mangroves. It is a relatively common species in the coastal areas of Guangxi, Hainan, Guangdong, Fujian, and Taiwan provinces. It is the only recorded species in my country. The only species in the moneyfish family. Money fish is a tropical-subtropical wide-temperature wide-salt species with strong environmental adaptability. It can not only grow and develop normally in seawater and brackish water, but also...
