Pond salmon farming techniques and methods
The squid has a slender figure, soft fins and rapid growth. It is a suitable feed for squid. By increasing the trophic index of the squid has a significant effect on the yield of the pond, the farming techniques and methods are described as follows: I. Pond conditions The pond area is 5-8 acres, the water depth is 1.2-1.5 meters, and the pond sludge is 20 centimeters large. Right, fresh water, no pollution, easy injection and drainage. Second, clear pond disinfectant fry three days before stocking need to do a good dry pond, drying pool, and then use bleach 2.5 kg, clear pond disinfection. Third, the water quality management After 5-7 days of fry under the pond with water, can not use fertilizer, water level control of 0.6-0.8 meters, 5-7 days after the appropriate fertilization, general chicken droppings 5-7.5 kg, acres, the whole pool Evenly, about 30 centimeters of the transparency of the pool water is controlled, and the normal pond is filled with water once every 7-10 days. The water level is controlled by 1.2-1.5 meters. Fourth, the summer fish pond fish fry is first used in the summer flower pond, time is from early June to late July, specifications 0.3 cm, mu volume is 30-60,000, need to go through 15-20 days to develop sub-Tang The pool, 2 to 3 cm, has a survival rate of 60-65%. Then, depending on the farming conditions and the amount of eel feeding, there is a plan to divide the stock. Fifth, fry stocking pond breeding breeding time for the end of 6 friends to early October, can be divided into three sections. At present, according to the city's aquaculture production, the first paragraph of the last paragraph of 6 Peng Peng to early August production (usually according to the city's market supply and demand of the first reproduction mainly), stocking specifications of 5000-7000 per kilogram, carp Miao 4-5 million tail / mu, out of pond specifications 120-150 per kilogram, 300-320 kg per mu. In the second segment of the 8th to the early 9th month of the month, stocking specifications range from early September to early October, stocking specifications are 1000-1200 per kilogram, carp seedlings are 10,000 per mu, and outlet sizes are 50-60 per mu. Production 160-180 kg. Reasonably arrange the collocation for each period, and the per mu output can reach 500-600 kilograms. Sixth, feeding and management of fish after the pond after the pond stage, mainly soy milk, vegetable cake supplemented, when the pulp is fed twice, after a week of fry cultivation, until the fish on the beach, in the pool pool beach "slurry" Feed should be enough for the healthy growth of fry. Generally, it takes 0.5 soybeans per 10,000 seedlings. After the pond is divided, the fry is used organic fertilizer according to the bottom fertilizer, generally, 100-150 kilograms per acre cultivating the red worm as a ramming material, and then feeding the cake. The production of 1 kg of squid generally requires 1.5 kg of cake. VII. Disease prevention and control Fish fry go to the pool for about a week, mainly to prevent the occurrence of “bubble diseaseâ€. To do this, it is necessary to clear the pond and regularly add fresh water. During the breeding period, the main prevention and control of trifoliate, oblique tubeworm, 1 mu water depth of 1 meter with 0.5 Pmm 100 net Quanchiposa, and then another 0.2 kg of fish frog rotten leather to stop bleeding Quanchiposa, so that the healthy growth of carp.
