Key Techniques and Daily Management Methods for Golden Apple Snail Farming
The golden apple snail, also known as the apple snail, originated in the Amazon River and is one of China's invasive species. It is extremely large, highly adaptable, grows very quickly, has strong reproductive capacity, and is very easy to produce high yields. However, its flesh has a poor taste and texture, so its food value is low; it is mainly used as feed for raising other aquatic animals. Below, let's take a look at its farming techniques with Qinnong Web.
1. Preparation of the Farming Site
A suitable pond can be chosen as the farming site. The area does not need to be too large: 3-5 mu is fine, and even a few square meters will do. The requirements are fresh water quality and an adequate water source. The water depth should be within 1 m. During farming, aquatic plants such as duckweed or algae should be planted on the water surface. This not only provides the golden apple snail with a shaded, light-protected living environment, but also provides natural feed and lowers feed costs. The area of aquatic plants should not be too large either; about one-third of the entire water surface is sufficient, as too much will have the opposite effect. For ease of management, bamboo poles can be used to enclose the water surface into several areas, and the bamboo poles can also serve as egg-laying sites for female snails. Many fish will feed on young snails, so the pond must be cleared and treated before farming, and filter nets should be placed at the drainage and water inlet openings, first to prevent other fish from mixing in, and second to prevent the snails from escaping.
2. Releasing the Seedlings
When releasing seedlings, this should be done in a planned way according to water quality, feed, and management conditions. Generally, for newly hatched young snails, about 5,000 can be stocked per square meter, while after half a month of growth, when the young snails reach a body weight of 2-3 g, 2,000-3,000 can be stocked per square meter. According to this ratio, as the snails continue to grow, the farming density should be gradually reduced; they can be stocked at a density of 5,000 per square meter, and as the snails grow, gradually harvest the large ones and keep the small ones. They can also be stocked according to adult specifications, and then harvested together once they have grown. When stocking, the snails should be grouped and raised according to the same growth specifications, so that their feed intake is consistent, which makes feeding management convenient.
3. Feed and Feeding
To raise golden apple snails quickly and well, the choice of feed and the feeding amount are extremely critical. Generally, the daily feeding amount is one-tenth of the golden apple snail's body weight, and as it grows, the feeding amount is gradually increased. The feed should also combine coarse and fine materials and be fresh and not spoiled. Generally, green feed and concentrated feed are fed together, with the concentrated feed accounting for 0.5% of the golden apple snail's body weight. When feeding, feed the green feed first, and after the green feed has been eaten, then feed the concentrated feed. This helps nutrient accumulation, promotes the snails' growth, and increases body weight. In addition, golden apple snails avoid direct sunlight, so the feeding time should also be noted. During the day, golden apple snails sink into the water to rest, and at night they come out to feed, so the best feeding time is in the evening.
4. Water Quality Management
Golden apple snails will grow extremely fast as long as there is sufficient feed, so if they eat a lot, they will excrete a lot. A large amount of excrement will cause water quality to continuously deteriorate, and poor water quality can easily lead to disease outbreaks, affecting the snails' growth or causing death. Therefore, water quality management is extremely important during farming. To ensure their healthy growth, the water should be changed frequently to keep the water quality fresh. In a still-water farming environment, the water generally needs to be changed once every 7-10 days, while in a micro-flowing water environment, it can be changed once every 20-30 days.
