Detailed Explanation of Key Technical Points for Pollution-Free Sea Bass Farming
1. Farming waters: Farming waters generally require a water depth of 2 m-2.5 m. Half a month before releasing the fry, spread quicklime over the surrounding farming waters to disinfect them. 2. Stocking density and disinfection of fry and fingerlings: The stocking size is 0.5 g/fish-0.6 g/fish, and the stocking density is 100 fish/mu-120 fish/sq m. Before

Experience and Technical Key Points for Pond Farming of Bass
1. Pond clearing and water cultivation. For ponds used to farm bass, it is best if conditions allow to dry the pond, remove silt and expose it to sunlight, especially for old ponds that have been farmed for many years. Disinfect once half a month before releasing fry, applying 50 kg of quicklime per mu or using 20 PPM bleaching powder with an appropriate amount of pond water for disinfection.

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 Disease Prevention and Control in Artificial Scallop Seed Rearing
During artificial seed rearing, scallop larvae are highly susceptible to bacterial and fungal infections, which cause mass mortality. Among the common bacterial diseases are Vibrio species; one type, Vibrio anguillarum, specializes in decomposing organic matter and can break down the larval velum within a very short time. This symptom occurs especially within
