(1) Choose a pond with an area of ​​2 to 5 acres, with a water depth of 1.5 to 2 meters. The fish pond will not leak, the water and fertilizer will be good, drainage and irrigation will be convenient, and the water supply will be sufficient and the water quality will be good.
(2) To kill the pathogenic organisms in fish ponds before they are stocked. It is generally 7 days to 8 days before the fish species are stocked, and the quicklime is 75 kg/mu ~ 100 kg/mu. 2 days to 3 days after the injection of new water, and manure 300 kg / acre ~ 400 kg / acre as a base fertilizer to cultivate natural food.
Second, fish species stocking
Fish stockings can be selected from April to May. Try to stock early, eat as early as possible and grow early. The stocking species requires a strong physique, no disease, no injury, and neat specifications. It is best to be sterilized before stocking, soak with 3% to 5% of normal saline for 5 minutes to 10 minutes or dip with 20 mg/up of potassium manganate for 30 minutes. The amount of stocking depends on the specific circumstances, generally 800 to 1000 mu / mu is appropriate, can be appropriate with some squid, squid, squid and so on.
Third, feeding and management
(a) feeding.
The fish species can be fed for 1 day to 2 days and the bait protein requirement is controlled at about 32%. The squid material and tilapia material can be used instead of feed. Feeding should follow the principle of “Four Setsâ€, and the amount of daily feeding should be 1% to 5% of the total weight of the fish. The specific quantity should also be determined according to the season, weather, size of the fish, eating conditions, and water quality, generally 1% in spring. ~ 3%, 3% ~ 5% in summer and autumn, generally two times a day to three times feeding.
(b) Fertilization.
The main raising fish is dominated by fertilization, supplemented by feeding. Largemouth bass is a staple food plankton in natural waters, and proper fertilization can save bait costs. Green manure is applied once every 10 days, with a dosage of 100 kg/mu ~ 150 kg/mu; a fertilizer is applied every 3 days to 4 days, and 1 kg urea and 2 kg of phosphate fertilizer are applied per acre. The fertilization time should be selected for sunny days. It should also be increased or decreased according to the water quality and the degree of water thinning. The transparency should be controlled at 20 cm to 25 cm.
(3) Water quality management.
It is necessary to insist on daily inspection of the pond and pay attention to changes in water quality. Good water quality can both promote growth and prevent disease. Sprinkle lime once every 15 days. The dosage is 15kg/mu~25kg/mu. Each time lime is splashed with lime for 1 to 2 days, 20 cm to 30 cm deep water is refreshed, which is conducive to the growth and reproduction of natural food. During the summer hot season, it is necessary to constantly update the water to prevent the water temperature from being too high and affect the growth of the fish. When the water quality is too fat, we must pay attention to changing the water and always maintain the water quality “fat, live, tender and cool†to facilitate the growth of the fish.
Fourth, fish disease prevention
As long as the husbandry and management are in place, the rouge fish rarely develops. The main measures for preventing diseases are:
(1) Before the fish species is under the pond, the disinfection of the pond must be thorough, and the fish should be disinfected before going down the pond;
(2) Sprinkle lime water once every 10 days to 15 days, with a dosage of 15 kg/mu ~ 25 kg/mu;
(c) 20 to 50 codfish per acre can prevent anchor head lice;
(D) fish disease epidemic season regularly every 5 kg of fish with 5 grams to 10 grams of furazolidone bait formulations, feeding for 3 days.
