4. Professional suggestions and precautions
1.Water quality testing should be carried out regularly: It is recommended to check the pH value (6.5-8.5 is preferred), dissolved oxygen (>5mg/L), and ammonia nitrogen content (<0.2mg/L) once a week.
2.Feeding management must be scientific: The daily feeding amount should be controlled at 3%-5% of the fish's body weight, and should be fed in 2-3 times. It is advisable to finish the fish in 15 minutes each time.
3.Pay attention to weather warnings: When the temperature drops sharply by more than 5℃ or the air pressure is lower than 1000hPa, the feeding amount should be reduced in advance.
4.Disease prevention must come first: Soaking fish bodies in 3% salt water for 5 minutes every month can effectively prevent parasitic diseases.
5. Emergency treatment plan
When it is found that crucian carp suddenly stops eating collectively, a three-step method of "stop-check-treat" can be adopted:
| steps | Specific operations | Time node |
|---|---|---|
| Step one: stop eating | Stop feeding immediately for 24-48 hours | The day of discovery |
| Step 2: Check | Test water quality, observe fish body surface, dissect and examine intestines | fasting period |
| Step Three: Treatment | Take targeted measures based on inspection results | After confirming the reason |
Conclusion
Crucian carp not eating is a common problem in breeding and fishing. Through scientific analysis and systematic investigation, effective solutions can be found in most cases. It is recommended that farmers establish daily observation records and accumulate experience data so that they can make quick and accurate judgments when encountering problems. The weather has changed frequently recently, so fishing enthusiasts are particularly reminded to adjust their fishing strategies according to temperature changes.
