1. The importance of disinfection of small fish
Disinfection of small fish can not only kill pathogens, but also reduce water pollution and avoid cross-infection. Disinfection is essential especially when new fish are introduced into the tank or when diseases appear in the fish group.
2. Common disinfection methods
| Disinfection method | Applicable scenarios | Operation steps | Things to note |
|---|---|---|---|
| salt water bath | New fish entering the tank, mild infection | 1. Prepare 3% salt water 2. Soak the small fish for 5-10 minutes 3. Observe the fish’s reaction | The time should not be too long to avoid stress |
| Potassium permanganate solution | Serious infections, parasites | 1. Prepare light pink solution 2. Soak for 10-15 minutes 3. Rinse thoroughly | Excessive concentration will harm fish bodies |
| UV disinfection | water disinfection | 1. Install UV lamp 2. Irradiate for 1-2 hours every day | Avoid direct exposure to fish body |
| Drug disinfection | bacterial infection | 1. Take the medicine according to the instructions 2. Isolate sick fish and treat them | Pay attention to drug residues |
3. Disinfection precautions
1.Control concentration and time:If the concentration of the disinfectant is too high or the soaking time is too long, it may cause harm to small fish.
2.Observe the fish’s reaction:During the disinfection process, the status of the small fish should be closely observed. If there is any abnormality, stop immediately.
3.Isolation and disinfection:New or sick fish should be disinfected separately to avoid infecting other healthy fish.
