I. Pond renovation
Pond area of ​​5 to 8 acres, rectangular, north-south to better. The bottom of the pool is required to be flat, sandy bottom, and the pool shore is firm, with a depth of 2 meters. The bottom of the tank is buried in the drain and equipped with an aerator. Before the stocking, dredge and disinfect the pond. Fertilize the basic bait to make the water green or brown.
Second, seed cultivation
Seedlings (1.5 to 2 cm in length) taken from the sea area are desalinated to a salinity of 4 to 7 Torr and put into a holding tank (1 salinity). Holding ponds are kept at a stocking density of 1 to 20,000 per acre, often flushing the pond with oxygen. The next day, the pond began to feed fresh live bait, such as zooplankton and red worm. Afterwards, it was gradually mixed with fish slurry, buoyant particles, bait, and fresh live bait, and domesticated until the fish larvae and buoyant pellet feed were fed. The daily feeding amount was 15% of the body weight of the fish and it was fed 3 times. Three days before the start of feeding, 3 grams of soil mold and 3 grams of vitamin C were used for every 50 kilograms of fish. The feed was fed once a day and fed three times. After more than 20 days, the fish fry grow up to 4-6 cm into the big pond.
Third, feed management
After the squid is sifted, it is bred by the size of the sub-pool. The stocking density is 2500 to 3500 per mu, and the water depth is kept at 1.5 meters or more. The pool water is suitable, and the lightness is 30 centimeters. Feed twice a day, the main feed for the fish gills and buoyant pellet feed, add vitamin B, C in the feed, the amount of daily feed in the pond fish body weight 60%. Monthly use of terramycin, vitamins and other mixed feed 2 times feeding, each feeding 3 days. Take a tour of the pond every day, turn on the oxygen at night or when the weather is hot and the air pressure is low. Change the water in time to keep the water in the pool fresh.
Fourth, disease prevention
The squids are prone to morbidity under artificial high-density culture conditions. Disease prevention must be strengthened. Drugs should be sterilized on farm ponds and food stations on a regular basis, and diseases should be treated as soon as possible. Focus on prevention of enteritis, gill disease, hemorrhage, hydromycosis, and parasitic diseases.
