Problems of Fish Rearing after the Spring Festival
The Spring Festival is one of the most significant traditional holidays in China, marking a time of family reunions and celebrations. However, after the festivities, aquaculture farmers should not overlook the important tasks that come with pond fish farming. In fact, the period following the festival is critical for preparing for the next production cycle. Here are some key points to consider:
1. **Timely Harvesting of Adult Fish**
After the holiday, it's an ideal time to harvest adult fish. Promptly catching and selling them helps clear the pond, recover capital, and prepare for the next round of fish farming. Delaying sales due to price fluctuations can negatively impact future production.
2. **Stocking Fingerlings at the Right Time**
For empty ponds, once the water temperature becomes suitable, fingerlings should be introduced promptly. Before stocking, ensure the pond is thoroughly cleaned and disinfected. Follow proper stocking patterns, species selection, and quantities to maximize efficiency.
3. **Water Quality Management**
Ponds that have been unused during winter often suffer from poor water quality. It’s essential to adjust the water by replacing 1/3 to 1/2 of it to improve conditions and promote healthy fish growth.
4. **Early Feeding Based on Temperature**
As spring begins, temperatures rise, and fish become more active. Monitor weather changes, measure water temperature regularly, and observe fish behavior. When conditions are favorable, feed them promptly to help them regain strength and start growing early.
5. **Disease Prevention and Control**
The post-holiday period is crucial for both harvesting and stocking, which can cause stress and injuries to fish. With rising water temperatures, bacteria multiply faster, making fish more vulnerable to diseases. After the ice melts, apply trichlorfon at 0.2–0.5 ppm, and a few days later, use a disinfectant to keep the water clean and prevent disease outbreaks.
In conclusion, the period after the Spring Festival is just as vital as the holiday itself for fish farming. Don’t let the busyness of celebrations distract you from these essential tasks. Proper management now ensures a successful season ahead.
