Problems solved by technology

[0003] Causes of the disease (1) High stocking density; (2) Poor water quality in ponds; (3) Inbreeding, resulting in a decline in fish species; (4) Excessive feeding of commercial feed and less natural feed lead to excessive body fat and resistance of fish. (5) Farmers lack awareness of disease prevention and litter sick and dead fish, resulting in an increase of pathogens in natural waters; (6) In the process of pulling nets in winter, inadequate disinfection work causes pathogens to invade the injured parts of fish and cause disease

Embodiment 1

[0016] A new method for preventing freshwater fish bacterial sepsis, comprising the following technical steps:

[0017] (1) Disinfect regularly around the fish pond, and deal with the disease in time when the disease is found;

[0018] (2) Fish out the sick and dead fish in time and bury them deeply;

[0019] (3) Splash and disinfect the whole pool with quicklime, bleach or chlorine dioxide every 5 to 10 days.

[0020] (4) Turn on the aerator and add new water.

[0021] (5) The vitamin C added in the feed can improve the fish's disease resistance; the amount of vitamin C added is added according to the standard of 100g / mu;

[0022] (6) Adjust the water quality of the fish pond every 1 to 2 weeks to maintain a good cleanliness.

Abstract

The invention discloses a novel method for preventing bacterial septicemia in freshwater fishes. The method includes the technical steps of 1, performing periodic sterilization around a fishpond, and timely treating diseases on discovery; 2, removing and deeply burying the fishes dead of disease; 3, splashing quick lime, bleaching powder or chlorine dioxide to the fishpond for sterilization every 5-10 days; 4, starting an aerator and injecting fresh water; 5, adding vitamin C, which helps increase disease resistance of the fishes, into feed according to the standard 100g / mu; 6, regulating water quality for the fishpond every 1-2 weeks so as to keep good cleanliness.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and more specifically relates to a new method for preventing freshwater fish bacterial sepsis. Background technique [0002] In recent years, due to the blind pursuit of freshwater fish production by farmers, the increase in breeding density and the large-scale promotion and application of pellet feed, fish bacterial sepsis has occurred more often. [0003] Causes of the disease (1) High stocking density; (2) Poor water quality in ponds; (3) Inbreeding, resulting in a decline in fish species; (4) Excessive feeding of commercial feed and less natural feed lead to excessive body fat and resistance of fish. (5) Farmers lack awareness of disease prevention and litter sick and dead fish, leading to an increase of pathogens in natural waters; (6) In the process of pulling nets in winter, inadequate disinfection work causes pathogens to invade the injured parts of fish and cause disease.
