Key Technical Points for Summer Stocking of Largemouth Bass in Ponds
1. Pond drying and disinfection. Aquaculture ponds must be drained and dried for 10-15 days, the pond embankments repaired, and quicklime or bleaching powder used for disinfection. 2. Fingerling rearing. First, use early-breeding fry from Guangdong raised in dedicated ponds from late April to early May, and divide them into separate ponds when they reach about 5 cm; second, use locally self-bred largemouth bass, and select fingerlings that are robust, uniform in size, healthy and disease-free. Stocking density is 800-1200 fish per mu.

Key Technical Points for Planting Grass and Stocking Snails in Crab Culture Ponds
With the expansion of crab culture scale and the improvement of intensive farming levels, the water quality of aquaculture waters has deteriorated, the quality of river crabs has declined, and diseases have worsened, affecting the improvement of river crab culture benefits. In recent years, Dalong Township, Dafeng City, Jiangsu, has adopted the method of planting grass and stocking snails to culture river crabs.

Experience in Stocking Fingerlings for Tilapia Pond Aquaculture
1. Selection of fingerling size for stocking. Adult fish farming generally involves stocking in the same year and harvesting in the same year, so the fingerling stocking size is generally 3-10 cm, which gives a high fingerling survival rate, large marketable fish size, and high economic returns. At present, the fingerling sizes for tilapia farming in China mainly fall into three

A Detailed Guide to Bullfrog Farming Techniques: Master Scientific Farming Methods
Before the tadpoles are stocked in the pond, the pond must be cleaned thoroughly and disinfected with 200 PPM bleaching powder. After the tadpoles metamorphose, they should be transferred to juvenile frog ponds in a timely manner; to prevent cannibalism, they should be graded and raised according to size in a timely manner. After they become adult frogs, an escape-proof wall must be built around the frog pond, with a height of about 1.5 m, and the pond water depth

What are the pond-clearing methods? Remember these five before stocking fish fry
Before stocking fish fry, the aquaculture pond must be cleared to kill various predatory small wild trash fish, harmful aquatic animals and plants, parasite eggs, pathogenic bacteria, etc., creating a good environment for the growth of adult fish. The following five pond-clearing methods are introduced: 1. Clearing the pond with quicklime. When carrying out drainage pond clearing (that is, draining the pond water to a depth of 5-10 cm of remaining water before clearing), use 60-70 kg of quicklime per mu of pond; when clearing without draining, use 125-150 kg per mu of pond for every meter of water depth (200 ppm).
