The transportation is convenient. It is close to the city and the urban area. The environment is excellent. There are no high-pressure lines crossing the pond, and there are no tall trees. The pond area is 5-10 mu, the water depth is about 2m, and more than 2 ponds are matched. The water source is of good quality and meets the standard of NY5051-2001.
Second, pond disinfection
Clear the silt of the pond and remove the weeds around the pond. The pool rafts are best protected by block stones or perforated plates. Before stocking, the fish should be treated with quicklime 75 to 100kg/mu or bleached 3-5kg/mu to disinfect wild fish and pathogens to improve the sediment quality of the pond.
Third, fish species stocking
The stocking time is mainly at the end of the winter and early spring. In the future, the fish species will be added in time according to the amount of fish and the amount of fish in the pond. The multi-species polyculture shall be practiced to stock different species of fish inhabiting the upper, middle and lower layers of the water body. Grass carp, carp, carp The main specifications are grass carp 2kg/tail, carp 0.5kg/fig, and carp 0.25kg/fig. In addition, it will be used with 90 mu of carp and 30 catfish per mu to facilitate the full use of water and regulate water quality. According to the source of the fish, it is possible to feed 20 pairs of carp (or black carp) per mu, and 20 carp (or carp). / Acre, Snapper 100 tails / acre, to facilitate the elimination of wild fish in the water, diseased fish, and improve the fishing interest of anglers. The stocking amount should be controlled within 500kg per acre of water surface. If the water source conditions are good, or the oxygen-increasing equipment is provided, the stocking amount can be appropriately increased. When the fish species are stocked, they must be strictly disinfected and generally soaked in a 3% saline solution for 7 to 10 minutes.
Fourth, improve water quality
The height of the vertical fishing ponds is high. To prevent floating heads and flooding ponds, fish ponds are required to have a transparency of 30-40 cm, a pH value of 7.0-8.0, and a dissolved oxygen concentration of 5 mg/L or more in water. Improved water quality is one of the key measures for successful breeding. The main methods are: firstly, adding new water regularly, or starting the aerator for 1 to 2 hours at noon; second, applying photosynthetic bacteria regularly, or splashing lime water, zeolite powder, etc.; Some aquatic plants such as water spinach, water hyacinth, water lotus, and duckweed are properly transplanted in fish ponds.
Fifth, reasonable feeding
Feed nutrition must be comprehensive and balanced, with a protein content of more than 32%, a moisture content of less than 10%, and feed as a pellet. Feeding method to achieve flexible use of "timing, positioning, qualitative, quantitative" method, that feeding time is set in the afternoon 4-5, the feeding position is located in the fishing hook, and set up as many feeding points as possible Daily feeds typically account for 1.5% to 2% of pond weight.
Six, pollution-free prevention and treatment of diseases
In the process of fishing pond fishing, the use of drugs is generally not advocated. Prevention should be done first, management first, and comprehensive prevention and control should be implemented. The first is to do a good job in general work such as disinfection of ponds, disinfection of fingerlings, environmental sanitation of ponds, and monitoring of water quality. The second is to maintain a reasonable amount of fish on the pond, generally should be controlled below 500kg/mu. The third is to strictly control the entry of fish and eliminate the pool of fish with pathogens. In the transportation process, the operation is light and the abrasion of the fish is minimized. Fourth, the use of green environmental protection fishery medicine, such as Chinese herbal medicine, biological agents, salt, lime and other drugs symptomatic medicine, prevention and treatment of fish diseases.
