The method of raising fishes and crabs was thoroughly cleaned with 75 kg of lime per acre in mid-April, and 200,000 grass carp, carp, carp, and carp were released on May 15. On May 20th, the size of 4,000 kg per kg was released. 2,000 kinds of bean crabs. Fish flower ponds were fed with soybean milk one month later, once a day. After 1 month, when the species length is 3 to 4 centimeters, feed concentrates will be stopped, and the calabash (flounder, also known as sesame moth) will be fed. After 1 week, we ate the body. The excrement discharged from grass carp and squid species can be used as both fertilizer and water, and can also be eaten by carp and carp. From the middle of June to the end of September, a total of 7,500 kilograms of calamus was fed. From July to September, the transparency of pool water should be controlled at 10-15 cm, so that the pool water can truly reach fat, live, tender and cool. After 10 months, fresh Chicken manure was fed and the amount of fish and crab was suitable for feeding. After October, the transparency of the pool water can be maintained at 5 to 10 cm.
Adjusting Water Quality Feeding chicken manure to ponds is very acidic, and quicklime must be used to regulate water quality. Generally, a pond with a depth of 1 meter per acre is splashed with 15 kg of calcined water and splashed once every 20 days.
Timely harvesting In mid-October, the capture of adult crabs needs to be well-handed. The premature hatchlings are not fat and the yield is not high. When they are too late, they become ashore and easy to escape. This is usually done one week after the gonadal maturation and before the crabs go ashore. Capture method: At night, flashlights are used to illuminate the water edge, and crabs that feed on the side of the pond are captured. The crabs are caught every 1 hour and captured continuously for 1 week. The crabs can be basically caught.
The benefits of nesting: Fish and crab are symbiotic and benefits are doubled. There is a natural ecological environment suitable for the growth of crabs in ponds. There are plenty of foods for crabs to feed on, and they are often better than stocking alone. Second, nesting in the fingerling pool is generally not the incidence of disease, can use less drugs or no drugs, so that there is no drug residue crabs, welcomed by consumers.
