Autumn raising squid
To improve the water quality of the pond and enter the autumn, the feed intake of the carp increases, and more waste is produced each day, which can easily lead to excessive levels of harmful substances such as ammonia nitrogen and nitrite in the water. Therefore, the water should be changed frequently, and water should be changed every 7 days. Change the water volume about 20 centimeters. Each 5-mu~6 mu codfish pond area is equipped with 3 kilowatts of oxygen aerators, so that it can open the noon for 2 hours to 3 hours at noon on sunny days. It can play a mixture of upper and lower water layers to eliminate oxygen debts and increase the dissolvability of fish ponds. Oxygen reserve. Open the aerator to dawn at about 12 o'clock in the evening. Encountered showers or hot weather, early in the night to start the aerator, at the same time with the plasma full of plasma spillage. Strengthen the fish's constitution to master reasonable breeding density and scientific polyculture, and stocking density is about 850 mu. It is required that the amount of fish fed each time is twice or three times the daily feed intake of squid, and every two days to three days should be added once to prevent the squid from eating too much food. Disease prevention and control For the bait fish that are planned to be harvested, sterilize the worms 3 days to 5 days in advance, and it is necessary to combine the feeding baits for 3 days to 5 days. After ensuring that the bait fish is healthy, it is then captured and put into the squid pool. Fall is the season for the high incidence of carp trichopluses and larvae. For this reason, early detection and early treatment must be done. Regularly catch 1 to 2 squid to fish clinics for microscopy and use different methods according to the number of worms. On the third day after killing the larvae, chlorine dioxide was disinfected with 200 grams per mu.
