Embodiment 1

[0017] 1. Pond requirements. The ideal pond area should be 10 mu, the water depth should be 2 meters, and the thickness of the silt should not exceed 20 centimeters. For every 10 mu of ponds, there is one aerator with a power of 3 kilowatts and one automatic bait feeding machine.

[0018] 2. Clean the pond. Drain the pool water in winter and freeze and dry for more than 20 days. Fifteen days before the fish species are stocked, 10 cm of water is used, and 150 kg of quicklime per mu is used for disinfection in clear ponds.

[0019] 3. Stocking of fish species. Before and after the Spring Festival, 1,000 grass carp fingerlings with a size of 200 g / kg, 300 fingerlings of crucian carp with a size of 15 / kg, 50 fingerlings of silver carp and 10 fingerlings of bighead carp with a size of 5 / kg were released per mu. Soak and disinfect the fish with 5% salt water for 5-10 minutes before stocking.

[0020] 4. Feed feeding. Mainly feed pellets, the protein content of the feed is 28-...

[0025] 1. Pond requirements. The ideal pond area should be 20 mu, the water depth should be 2.5 meters, and the thickness of the silt should not exceed 20 centimeters. For every 10 mu of ponds, there is one aerator with a power of 3 kilowatts and one automatic bait feeding machine.

[0026] 2. Clean the pond. Drain the pool water in winter and freeze and dry for more than 20 days. Fifteen days before the fish species are stocked, 20 cm of water is used, and 150 kg of quicklime per mu is used for disinfection in clear ponds.

[0027] 3. Stocking of fish species. Before and after the Spring Festival, 1,000 grass carp fingerlings with a size of 250 g / kg, 300 crucian carp fingerlings with a size of 20 / kg, 50 silver carp fingerlings with a size of 6 / kg, and 10 bighead carp fingerlings were released per mu. Soak and disinfect the fish with 5% salt water for 5-10 minutes before stocking.

[0028] 4. Feed feeding. Mainly feed pellets, the protein content of the feed is 28-32%. ...

Description

technical field [0001] The invention relates to the technical field of aquaculture models, in particular to a high-yield cultivation method for grass carp ponds. Background technique [0002] Grass carp farming mostly adopts traditional methods such as lakes, cages, and ponds. Grass carp English name: Grass carp. The only species of the genus Grass carp in Cyprinidae Cyprinidae, also known as white grass carp, grass root fish. It inhabits rivers and lakes in plain areas, and generally prefers to live in the middle and lower layers of water and areas with many aquatic plants near the shore. It is lively, swims quickly, and often looks for food in groups. A typical herbivorous fish. Overwinter in the deep waters of main streams or lakes. Broodstock have the habit of swimming in the breeding season. Because of its rapid growth and wide source of feed, it is one of the four major domestic fish in freshwater farming in China. Grass carp is rich in unsaturated fatty acids, ...
