Inshore cage cultured fish disease control method

Abstract

The invention provides an inshore cage cultured fish disease control method. The purposes that the disease control effect on cultured river crabs is obvious, and yield and income of a fishery industry are increased are achieved. The inshore cage cultured fish disease control method includes the steps that in a river crab cultivation preparation stage, a crab pool is treated, wherein the treatment process is characterized by including the steps that after the crab pool is filled with water, medicines, with certain concentration, are utilized to conduct insect killing, sterilization and disinfection on the crab pool, and therefore pathogens of river crab diseases and middle important hosts, namely various shellfishes, of the pathogens are killed; after a certain period of time, quick lime is mixed with water according to a certain dosage and then is utilized to splash the whole pool. Through the control method, the occurrence rate of river crab diseases can be reduced, especially the morbidity of trembling diseases of the river crabs can be reduced, and the cultivation yield of the river crabs and economic benefits can be improved.

Description

technical field [0001] The invention relates to a method for preventing and controlling fish diseases in offshore net cage culture. Background technique [0002] In the cultivation of river crabs, with the continuous expansion of the cultivation scale and the continuous increase of the cultivation years, the diseases of river crabs are becoming more and more serious, especially the occurrence of "shivering disease" of river crabs, which often leads to the annihilation of the entire army of cultured river crabs. Currently, the commonly used The method is to mix the drug with water to spray the whole pond for disinfection when the crab is ill, and at the same time use the drug to make bait for the crab. The control effect is not obvious, and the death phenomenon of river crabs is serious, which not only wastes money, but also increases the drug residue in river crabs, and also pollutes the water body environment. Contents of the invention [0003] The invention provides a d...
