(3) preparing a spawning pond: the spawning pond is a rectangular cement pond with the length of 10m, the width of 4m and the height of 1.2m, is dark, is convenient to water inlet and discharge, and is provided with oxygen charging equipment; after the spawning pond is selected, the spawning pond is washed clean by clean water, and clean water is injected; the California perch eggs are extremely strong in viscosity, the ovaries are made by fixing palm pieces on a special iron stent mesh, two palm pieces are laid on one iron stent mesh, the quality of the palm pieces is good and large enough, and the back surfaces of the palm pieces are fixed for half a week by using thick iron wires; preparing 1 iron bracket net sheet for every 2 parent fishes; adding 70cm-80cm liters of clear water after the ovary is finished;
(4) selecting mature parent fish: selecting male fish with rough abdomen, enlarged abdomen and capable of squeezing milky semen, and selecting female fish with smooth abdomen, ruddy genital pore and enlarged abdomen; the ratio of male to female is 1: 1;
(5) artificial hastening parturition: the injection medicine is luteinizing releasing hormone analogue LRH-A2, diutanone maleate (DOM) and chorionic gonadotropin (HCG), and 3 kinds of medicines are mixed and injected; the injection dose is as follows: LRH-A of 4g/kg parent fish body weight2+2mg/kg of DOM of parent fish weight +800Iu/kg of HCG of parent fish weight; female fish is injected into abdominal cavity of pectoral fin for 1 time, and the injection dosage of male fish is reduced by half; the spawning induction time is selected from 4 months to 5 months;
(6) hatching: generally controlling the water temperature to be 20-24 ℃, starting spawning within about 72 hours, immediately fishing out the iron support with the palm sheets once the spawning is found, removing the palm sheets, hanging the palm sheets on hooks of a wood frame in an incubation pool, and splashing compound iodine solution diluent to prevent saprolegniasis; putting 10-15 oxygen heads into the hatching pond for oxygenation, keeping the oxygen sufficient, controlling the water temperature at 27-29 ℃, demoulding after about 56 hours, and changing the yolk sacs into flat-swimming fries after 3 days, wherein the fries begin to eat;

When most fry bodies are more than 2cm long, all the weever fries are transferred to a cement pool with the length of 20 meters, the width of 2 meters and the depth of 60 centimeters for underground water micro-flow water circulation breeding. 3-4 times of daily bait throwing, wherein the daily bait throwing amount is 5-10 percent; changing 1/4 water every 2 days, and sucking dirt once in the feeding area by using a hose with the diameter of 3-4cm every 2 days; until the fry is 4-5cm, the fry can pass through a screening pond and is put into an earth pond for stocking;
(5) disease prevention and treatment: in the 5 months, the water temperature rises, and the garlicin and the vitamin C feed additive are added once a week to mix and feed to prevent the occurrence of diseases, such as ichthyophthiriasis, maturity diseases and the like, which are common diseases of micropterus salmoides;
the defect that the ichthyophthiriasis is treated mostly by adopting the defect that the ichthyophthiriasis is not high-temperature-resistant, the water temperature is increased to 27-29 ℃, and after 24 hours, mercury nitrate solution with the concentration of one part per million to two parts per million (0.1-0.2 ppm) is prepared for splashing, 2 times a day, and the ichthyophthiriasis can be cured in 2-3 days;
treating mature body disease of Micropterus salmoides, preparing 40ppm formaldehyde solution, thoroughly changing water after 12h, feeding with 3 terramycin according to 40 jin of feed for 1 day and 2 times, wherein the feeding amount is 1/2 at ordinary times, and the disease can be cured in 2-3 days.
The method provides a good growth environment for the micropterus salmoides through scientific artificial propagation and fry breeding methods, avoids the occurrence of plant diseases and insect pests, remarkably increases the growth speed and immunity of the micropterus salmoides, improves the yield and survival rate of the micropterus salmoides, has good market prospect and is suitable for popularization.
