General aquatic light, transparent layer of more than 50 cm of fish ponds every 2 to 3 days fertilization once per mu into livestock manure 100 to 150 kg. 4. Fertilize according to the weather, water quality and fish activities. General temperature suitable, refreshing can be more appropriate; sultry, cloudy and thunderstorms before the best not to fertilize; aqua light, less than the appropriate biological feed organisms. Aqua if brown, yellow-green, indicating water quality, bait
