The amount of fertilizer should be determined based on the fertility of the water and the quality of the fertilizer. Generally, apply 60 to 90 kg of human and animal manure per mu, or 100 to 150 kg of livestock manure. If chemical fertilizer is used, follow a nitrogen-to-phosphorus-to-potassium ratio of 1:1:0.5. When applying, first crush it, mix it with water, and splash it evenly over the entire pond. The total amount per mu is 3 to 7 kg, with each application spaced 5 to 10 days apart. Keep the pond water a yellowish-brown or yellow

What are the four key points to get right for fish farming at the start of spring?
1. Fertilization: In early spring, when the pond water temperature stabilizes at 8°C-10°C, start applying supplemental fertilizer to cultivate natural food organisms in the water. The amount of fertilizer should be determined according to the fertility of the water quality and the quality of the fertilizer. Generally, apply 60-90 kg of human excrement and urine per mu; or 100-150 kg of livestock manure. If chemical fertilizer is used, follow a nitrogen-to-phosphorus-to-potassium ratio of 1:1:0.5. When applying, first crush and mix with water, then splash evenly over the whole pond, with a total amount of 3-7 kg per mu, and an interval of 5-10 days between each application. Keep the pond water quality yellow-brown or yellow-green, with a transparency of 30 cm
