Embodiment 1

[0020] A method for the prevention and treatment of freshwater fish melon worm disease is characterized in that, after being diagnosed as fresh water fish small melon worm disease, it comprises the following steps: first, use 60 ° high liquor in the water body of culturing fresh water fish, and the dosage is 1.5g Sprinkle evenly per m³; after an interval of 4 hours, use Protozoon (the main components are diammonium hydroxide and ethylenediamine, the active ingredient is greater than 45%) in the water body at a dosage of 0.22ml / m³ for even sprinkling, and use it once a day ; After 3 times of continuous use, finally use florfenicol in the water body at a dosage of 4mg / m³ for even splashing.

Embodiment 2

[0022] A method for the prevention and treatment of freshwater fish melon worm disease is characterized in that, after being diagnosed as fresh water fish small melon worm disease, it comprises the following steps: first, use 60° high-altitude white wine in the water body of cultivating fresh water fish, and the dosage is 1.7g Sprinkle evenly per m³; after an interval of 4 hours, use Protozoon (the main components are diammonium hydroxide and ethylenediamine, the active ingredient is greater than 45%) in the water body at a dosage of 0.26ml / m³ for even sprinkling, and use it once a day ; After 3 consecutive uses, finally use florfenicol in the water body at a dosage of 3.8mg / m³ for even splashing.

Embodiment 3

[0024] A method for the prevention and treatment of freshwater fish melon worm disease is characterized in that, after being diagnosed as fresh water fish small melon worm disease, it comprises the following steps: first, use 60 ° high liquor in the water body of cultivating fresh water fish, and the dosage is 1.9g Sprinkle evenly per m³; after an interval of 3.5 hours, use Protozoon (main components diammonium hydroxide and ethylenediamine, active ingredients greater than 45%) in the water body at a dosage of 0.3ml / m³ for even sprinkling, and use it at intervals of one day Once; after 2 consecutive uses, finally use florfenicol in the water body at a dosage of 3.5mg / m³ for even splashing.

Abstract

The invention provides a method for preventing and treating ichthyophthiriasis of freshwater fish. The method comprises specific steps as follows: high-alcohol baijiu with the alcohol strength of 60 V / V or above is firstly used for uniform splashing; after 3-4 h, a protozoon killer is uniformly sprayed to water and used once every other day; after the protozoon killer is continuously used 2-3 times, finally, florfenicol is used for uniform splashing. By means of the method, ichthyophthirius multifiliis can be effectively stripped from body surfaces and gills of fish and thus can be more efficiently and thoroughly killed, and the survival rate of the fish is increased; meanwhile, the method is applicable to almost all freshwater fish, is wide in applicable range, convenient to use, short inuse cycle and remarkable in pesticide effect, meets the aquaculture demands of the freshwater fish at present and has very great promotion value and huge market potentials.

Description

technical field [0001] The invention belongs to the technical field of aquaculture disease prevention and control, and in particular relates to a method for prevention and treatment of freshwater fish melon worm disease. Background technique [0002] Small melon worm, also known as white spot disease, is a common parasitic disease in freshwater fish farming. It has a high incidence and mortality rate, is more harmful, and has a low cure rate. Economic losses. The pathogen of the small melon worm is the multiseed small melon worm, which is a protozoan belonging to the family Ophryoglenidae of the order Hymenostomatida, and it often parasitizes on the skin surface, fins, and barbels of fish. , chin whiskers and gills, etc., and some can also parasitize inside tissues such as muscles, because after infecting fish, it will stimulate the secretion of mucus and vesicles formed by tissue proliferation, making it difficult for drugs to kill them. After the fish are infected with t...
