Detailed Explanation of Key Points for High-Yield Largemouth Bass Farming Techniques
Largemouth bass has extremely delicious flesh and is rich in nutrients. It is highly favored by consumers on the market and is also one of the common and important economic fish species. Because it can grow in both seawater and freshwater, the area of artificial farming is continuously expanding. Below, QinNong Net brings you the high-yield farming techniques for largemouth bass. Let's take a look together.
1. Farming Preparation
Before farming, preparation must first be done. Choose a large pond with an area of 6-10 mu. If it is too large, it is not easy to manage; if it is too small, the water body is unstable. This area is the most suitable. The water depth should be above 2 m, requiring sufficient water sources, clean and pollution-free water quality, and convenient transportation. Before releasing the fry, the pond must be disinfected. First drain the pond water, expose the pond bottom to the sun, then use bleaching powder or lime powder for disinfection and sterilization, maintaining the water depth at about 20 cm. Soak and splash, and after one week, water can be added to 1 m for cultivation.
2. Temporary Rearing and Stocking of Fry
The farming history of largemouth bass is relatively short, and the farming techniques are not yet fully mature. There is no large-scale fry breeding base, and the fry mainly come from sea catching. Fry are caught in spring. There will be losses during catching and transportation, reducing the survival rate, so during this period temporary rearing must first be carried out. Cage farming is more convenient for temporary rearing. Generally, 3000 fry are temporarily reared per cubic meter of water, and the density can be reduced according to the size of the fry. During temporary rearing, feed Artemia larvae or marine and freshwater copepods for the first 7-10 days, then feed fresh minced fish. When the fry grow to 8-10 cm, they can be released into the pond for farming.
3. Feeding Management
Largemouth bass is mainly fed with low-value trash fish. In artificial farming, the bait is also mainly low-value trash fish, supplemented with artificial compound feed. During farming, largemouth bass grabs food quickly and has a large appetite, so each feeding should be regular and quantitative, with careful observation. During feeding, observe whether the largemouth bass is full to avoid wasting bait. Pay attention to the method when feeding. First feed a small amount of bait to attract the largemouth bass to come and grab food, then feed all the bait. When they sink and no longer grab food, stop feeding. The number of feedings should vary according to temperature and seasonal changes. In spring and summer each year, which is the peak growth season for largemouth bass, the number of feedings should be increased, generally 4-5 times per day; while in early spring and late autumn, when the temperature is lower and unsuitable for largemouth bass growth, the number of feedings needs to be reduced.
4. Other Management
In addition to feeding, inspections should also be carried out several times every day to observe problems in the farming pond, and abnormalities should be dealt with promptly. This mainly includes water quality, largemouth bass activity, escape prevention, and disease prevention and control work. Water quality management mainly involves observing water color, smell, and transparency, and dealing with problems promptly when found. Largemouth bass activity involves observing whether the largemouth bass is active. If its activity is insufficient and it looks listless, the cause must be found and then dealt with. Escape prevention requires paying attention to the surroundings of the pond to see whether there is any largemouth bass escaping. Disease prevention and control work is especially important. Strengthen management at ordinary times, and when diseases are found, apply the right medicine promptly.
