California crickets are commonly known as bigmouth bass. They are carnivorous, warm-water fish, and are native to the rivers and lakes of North America. They have the characteristics of fresh meat, large individuals, fast growth, strong adaptability, less disease, and easy catching. First, the conditions of the pond area of ​​2-3 acres is appropriate, the water depth of 1.5 meters or more, adequate water, good water quality, irrigation and drainage convenience, no pollution. The subsoil is loamy soil. It is best to lay a layer of sand around it to keep the water well. Second, the fish stocking pond raises the California crickets, appropriate mixed flowers, white peony, etc., in order to remove feed residues and regulate water quality. Acre reared with a tail weight of 10 grams of California salmon species 1000-1500 tails, with stocking 100-200 tail flowers, alum. The stocked California catfish species require neat specifications, robust physique, active swimming, and no disease or injury. Third, feeding and management 1, feed California salmon for carnivorous fish, can be fed chopped small trash fish. The size of the fish is determined by the individual size of the Californian fish. Large-sized fingerlings that have just been stocked are generally cut into small pieces 0.5 cm wide. As the fish grows, the fish pieces gradually widen to 1 cm, 1.5 cm, 2 cm. 2. Tamed-breed fish stocks are not stocked just because they are not used for a while, and they will not eat for 2-3 days. Therefore, they need to stop for 2-3 days and then feed on tame food. The method is: first throw small pieces of fish along the edge of the Tanggu, 1.5 kg each time, daily cast 2-3 times, time is 1 in the morning and 1 in the afternoon, through a week of tame food, most of the fish can come to grab food. 3, reasonable feeding and feeding to achieve regular, quantitative, qualitative, positioning. When the water temperature is high in summer, it is fed 2 times. When the spring and autumn water temperature is above 10° C., it is fed once in the afternoon. When the water temperature in winter is below 10° C., it is basically not fed. The amount to be fed depends on the water temperature, weather, and water quality. The amount of juvenile fish fed on the day is 8%–10% of the fish, and the amount of feed on the fish stage is 5%–8%. 4. Routine management Due to the poor ability of California to withstand hypoxia, the requirements for water quality during breeding are relatively high. It is necessary to change the water according to the weather and water quality conditions. Feeding the pond once every 35 days or so, the pond is not divided as much as possible during the breeding process to avoid fish body damage. Fourth, the prevention of fish diseases California has strong resistance to disease, generally less incidence, only when due to operation and other factors caused by the scrape when the easy to disease, so as to minimize the number of points. Usually regular use of 0.1 mg / kg concentration of chlorine fines for disinfection, when the onset of oral administration of norfloxacin, oxytetracycline and other drugs.
