Pond farming squid technology
Squid is a wide-temperate, wide-salt, short-food chain estuary fish that feed on plant foods. It has the advantages of delicious meat, less disease, and rapid growth, suitable for living in the sea, brackish water and The main farmed fish in freshwater waters. I. Preparation before stocking Renovate the pond with 15-20 kilograms of tea cake per acre or disinfect with 100-150 kilograms of quick lime. 2. Water Quality Cultivation Carp likes fertilizer and water. After disinfecting in the clear pond, let the sun shine for a few days, turn the sediment and then expose it for 10 days, then you can inject new water, fertilize or use EM to develop water quality. In the water inlet, it is blocked by a plastic net to prevent wild fish from entering the pool. Second, the breeding method of raising squid monoculture and polyculture two modes. According to the inhabited water layer and different food habits of different fishes, polyculture, so as to give full play to the potential of the water body and the rational use of feed, can obtain better aquaculture benefits. In the production practice, ecological polyculture modes such as Macrobrachium praecox, Penaeus praecox, Shrimp, Penaeus vannamei, and Scylla serrata are effective. Third, aquaculture technology measures 1. Seed rearing is flexible according to the different conditions of various ponds. General requirements of specifications 4 cm or more; stocking stocks to be robust, complete scales, plump body, smooth body color, swimming and lively and normal. It is advisable to use 1200-1500 tails per acre for monoculture, and 250-300 tails per acre for polyculture. The stocking time should be determined by weather changes, and it is generally most appropriate to stock up before the Ching Ming Festival. 2. Feeding the feed Throughout the breeding process, feeding feeds insists on the principles of “Three Looks†(see the weather, seeing the water color, watching the fish activity feeding) and “Four Ding†(quality, quantity, timing, positioning). According to the size of the fish, the amount of feeding is flexibly adjusted in different seasons. Do not put sour, spoilage feed. Two times a day feeding, 9-10 am, 3-5 pm, and according to the weather changes, sunny days more cast, less rainy days of hot and humid cast; fish activities more normal vote, when the incidence of less vote. The amount of bait is 5%-10% of the fish's body weight. In the early stage of breeding, if there is a duck pond, duck manure and water, plankton in the water is very rich, which can reduce feeding. 3. Feeding management In order to prevent floating heads of fish and avoid pans, in addition to strictly controlling the amount of feed, in the summer heat and hot weather, install an aerator, stick to the pond twice a day, and observe that fish activities are abnormal, and take emergency actions in time. Measures, inject fresh water, start the aerator, because the squid swimming quickly and good jump, set a net at the inlet and outlet to prevent the escape of the carp. 4. Diseases The common diseases of salmon are parasitosis and watery mildew, but bleeding has recently been discovered. The parasites are mainly fish gills and nematodes, which invade the fish body and abdominal cavity and cause death. Sarcoidosis is often caused by a fish body bump infection. Regularly use bleaching powder, quicklime, or fish and fish gills to disinfect the water twice a month. Frequently remove the sewage sludge, aquatic weeds and poolside weeds in the pond, timely replace the new water, improve the water environment, keep the water fresh and prevent Disease occurs. 5. The harvest is timely harvested according to the market conditions and the growth of the fish to increase economic efficiency. General feeding 7-8 months, individuals up to about 500 grams, can be marketed. Monoculture can reach more than 400 kilograms per mu, and polyculture of 120 to 150 kilograms per mu.
