The purpose of farming mud loach is to increase economic efficiency, and the most effective way to increase economic efficiency is to increase the length of the loach, through long-term practical proof: autumn is the golden season for loach, but in practice it must be good Four off:
One, put a good feeding and fertilizer off.
Generally, fertilization and feeding amount in September to November should account for about 30% of the total annual fertilization and feeding amount. When applying organic fertilizer, it should be a small number of times, so as to avoid over-flooding caused by pond fish floating head; application of inorganic fertilizer, per acre can use carbon ammonia 5 ~ 7.5 kg, or urea 2.5 ~ 3.5 kg. After the "white dew", it should be mainly fed with concentrate feed. ?
Second, turn off the management of good water quality.
After the fall, the temperature dropped, and the amount of bait in the fish ponds was relatively increased. Therefore, the water should be changed frequently to keep the fish ponds fresh and fat and not dirty.
Third, to prevent floating head off.
For the individual intensively-intensified Tangkou, because of the large amount of feed, the content of organic matter in the water is high, and the oxygen consumption factor is also increased, so it is prone to anoxic floating head phenomenon. You can turn on the aerator in the evening or early morning, or add new water to adjust.
Fourth, the prevention and control of good fish disease.
From September to November, every 15 to 20 days, fish ponds with a depth of 1 meter per acre need to be sprayed with quick lime 15 to 20 kilograms each time, and 300 grams of bleaching powder can also be used to disinfect the fishpond bags.
