Affected by market factors, the sales of adult fish in Dongchangfu District have been slow since last year, and some farmers even haven’t fished in Tangkou. Due to the large backlog of adult fish, the Tangkou mouth is not open, coupled with the abnormal climate change in the recent period, which has brought about no significant impact on the fish stocking work in 2016. In order to eliminate this unfavorable situation in a timely and effective manner, the majority of breeding Households should effectively grasp the following tasks:

1, do a good job when the fish stocking. When the fish species is stocked, the wounds on the scraped parts of the fish have not yet completely healed. In addition, with the rise of temperature in the spring, it is very easy to infect the water mold and bacteria. For this reason, for the stocks that have been stocked at the end of the season, farmers can perform 1-2 disinfection operations depending on the actual situation. The types of drugs can be selected from chlorine dioxide, trichloroisocyanuric acid tablets, bromochloroheine, etc. Chlorine preparations.

2. For Tangkou, which is still stocking, the water quality of aquaculture waters should be lean, and the amount of water should be increased as much as possible. When fish stocks are stocked, they must be strictly disinfected. It is recommended to use potassium permanganate or salt water for disinfection. After the stocking is finished, 1-2 times of whole-cell sterilizing work will be carried out within 3-5 days. The types of drugs are mainly chlorine preparations.

3. As the water temperature gradually increases, the fish's activity and physical energy consumption increase. To ensure that the fish can enter a good growth state as quickly as possible, the current number of foods to be fed and the amount of food to be fed should be actively prepared. Based on the stock of the main fish and stocking species, reasonable choices can be made.

4, do a good job of prevention and treatment of fish parasites in the spring. On the basis of water quality management and food feeding, the prevention and killing of fish parasites must be done in a timely and serious manner.
