After the fall, water temperatures start to decline, and fish activity gradually decreases. This period is considered the golden phase for fish growth, so it's crucial to take proper measures to support their development. Here are some key points to focus on:
First, enhance feeding practices. During this time, the diet should be concentrated, especially for bottom-feeding species. It's important to balance fine and coarse feed to ensure a well-rounded and nutritious diet. For example, grass carp should be given fresh grass, while silver carp require more plankton-like materials. Carp and other species benefit from proper fertilization to maintain their health and growth.
Second, manage water quality effectively. It's recommended to add water 4 to 5 times a month, with each addition being about 5% to 10% of the pond's volume. Additionally, lime should be sprinkled every half a month at a rate of approximately 20 kilograms per acre to maintain optimal pH levels and improve water clarity.
Third, monitor fish size and harvest those that have reached marketable size. As the season progresses, more organic matter accumulates at the bottom of the pond, increasing the risk of poor water quality. Therefore, it's essential to prevent flooding during rainy periods by ensuring proper drainage systems are in place.
Lastly, disease prevention is critical. After the fall, fish are more prone to diseases such as gill rot and enteritis. Local farmers have successfully used a homemade remedy consisting of vegetable oil and ginger. The formula is as follows: mix 750 grams of vegetable oil with 250 grams of chopped ginger. Heat the oil in a pan, then add the ginger and cook for 20 minutes. Remove from heat, let it cool slightly, and mix with an appropriate amount of water. This mixture can be spread throughout the pond, especially near feeding areas. Apply once daily or every other day, and use it twice a day if possible. It's best to apply it on sunny days and change part of the water after five days to maintain good water quality.
