First, the cultivation of fish species When the yolk film of the hatched fish fry disappears and the body color turns black, it can be transferred to a special breeding pond for rearing. Feed mainly leeches, supplemented with egg yolk and so on. After 15 to 20 days of breeding, when the fish grows to 3 cm in size, they should be screened in time, fed by grading in separate ponds, and enter the breeding stage. The main feed for the fingerlings is leeches. After the fish is up to 5 cm in size, the starter can start to feed with the additive-inducing compound feed. The daily amount of fish is 3% to 10% of the total amount of fish. At this stage, special attention should be paid to preventing self-sustained food. In addition to feeding the food, the control measures must be performed regularly and strictly to screen the fry in the whole pond and feed it in separate pools. When the fry grows to about 10 cm, it can be put into large ponds or ponds for adult fish breeding.
Organic materials: also known as organic polymer materials, generally by C, H, O and other elements of the relative molecular weight of more than 100,000 (of course, there are other elements, such as S or P, etc.) generally speaking, solubility (divided into two kinds of swelling and dissolution), thermoplasticity (high temperature into the kind of viscosity) And thermosetting (seemingly low temperature and return to solid state), strength characteristics (than carbon or steel and other materials made of general strength is about twice its strength), electrical insulation, general organic materials have rubber, cellulose, protein, starch, high polymer, etc.

Second, the large-mouthed aquaculture of adult fish has strong adaptability. It can be cultivated in ponds alone, or mixed with other fishes, and it can also be intensively cultured in cages and flow pools. Currently, most of the popular fish ponds are raised in ponds. Single fish ponds should use a fish pond with sufficient water sources and convenient irrigation and drainage. Before the fish species are stocked, they must be cleared of silt and then disinfected with quicklime. Under the premise of guaranteeing the quantity and quality of feed, 2500-3000 tails of 10 cm seeds should be placed every 667 square meters (1 acre), otherwise the density should be reduced relatively. Feed can be used to "fish fish", that is, feeding fish or fry, tilapia and flies, quail, etc., fed twice a day, 9 to 10 o'clock in the morning, 5 to 6 o'clock in the afternoon vote Feed it once. The daily feeding amount is 3% to 8% of the total fish body weight. Feeding should be scheduled and fixed, and bait stations should also be set up for inspection. According to the water temperature, weather, etc. during feeding, the amount of investment should be increased or decreased flexibly. Strengthening water quality management, keeping fresh water in the pool, and preventing oxygen-deficient floating heads are the key to successful large-mouth breeding. When it is estimated that the fish has a floating head danger, the fertilization and feeding should be stopped. The grass or foodstuffs that have been put in should be promptly removed. If there is a large area of ​​floating head, in addition to a large number of flushing and open aerators, at the same time sprinkle salt to rescue (water depth of 1 meter per 667 square meters of water with 1 kg Quanchiposa salt water) can achieve better results. It also supports the increase of oxygen for some 667 square meters of plankton in the squid and squid consumption pool. Normally, new water should be filled regularly, and new water should be added before noon or 2 or 3 o'clock in the afternoon. Add 3 cm of water each time, but do not add water in the evening to prevent the rapid convection of the upper and lower water layers causing floating heads. Ponds with inconvenient drainage and irrigation or ponds with water shortage should be equipped with aerators to increase oxygen, in order to ensure that the pool water has a higher dissolved oxygen content. The principle of use of aerators is: In sunny days, especially in thunderstorms, it is necessary to insist on aerators at noon, and on cloudy days in the early morning of the next day, rainy days or rainy fishes, and turn on in the middle of the night. Attention should be paid to reservoirs that do not have a base, and river rafts are not suitable for stocking large-mouthed fish. Paddy fields with a depth of less than 40 cm and no deep-water fish letters should not be stocked with large-mouthed fish.
Third, the disease prevention and control of large-mouthed disease resistance is strong, especially in adult fish farming, less disease, but in the seedling stage, bacterial disease or viral, parasitic complications often lead to a large number of diseases death. Practice has shown that using 0.3-0.4 mg/l crystal trichlorfon solution or 0.4-0.5 mg/l copper sulphate, ferrous sulfate mixture (5:2) solution throughout the pool can better Prevention of a variety of parasitic diseases. A 1 mg/L bleach solution spreads across the whole pool and has a certain effect on bacterial fish disease. The medicine baits made of oxytetracycline, sulfonamides, and viral spirits have significant curative effects on the prevention and treatment of intestinal diseases. During the growth period of adult fish, 15 to 20 mg/litre quicklime water is periodically spilled into the fish pond to maintain the cleanliness of the fish pond and bait station and have special effects on the growth of the bigmouth bass.
