[0015] Example 1
[0016]1) Preparation before breeding: Drain the muddy bottom of the aquaculture pond water and expose it to the sun until the bottom mud cracks. Use quicklime to clear the pond before stocking. Use 55kg of quicklime per mu for 10-13 days before stocking. Kill fish and harmful microorganisms, improve the bottom quality of the breeding pond, filter and receive the water with an inlet net, filter and receive the water with a 60-mesh inlet net at a water level of 60cm, fertilize, and cultivate the pond water; the water depth is 1.5 ~ 1.6m, and the breeding pond is preferably an estuary Area water pond. According to the algae breeding situation, proper fertilization can be used to cultivate the pond water. Muddy bottom material is conducive to burial and overwintering of blue crabs.
[0017] 2) Select the mating female crab after the beginning of autumn and the female crab confirmed to have mated. Since the beginning of autumn is the mating season of blue crabs, you ...

[0025] 1) Preparation before breeding: Drain the muddy bottom of the aquaculture pond water and expose it to the sun until the bottom mud cracks. Clear the pond with quicklime before stocking. Clear the pond with 50kg quicklime per mu 13-15 days before stocking. Kill fish and harmful microorganisms, improve the bottom quality of the breeding pond, filter and receive the water with a water intake net, filter and receive the water with a 60-mesh water intake net at a water level of 60 cm, fertilize, and cultivate the pond water; the water depth is 1.7 ~ 1.8 m, and the breeding pond is preferably an estuary Area water pond. According to the algae breeding situation, proper fertilization can be used to cultivate the pond water. Muddy bottom material is conducive to burial and overwintering of blue crabs.

[0032] 1) Preparation before breeding: Drain the muddy bottom of the aquaculture pond water and expose it to the sun until the bottom mud cracks. Use quicklime to clear the pond before stocking. Use 60kg quicklime per mu for 12 to 14 days before stocking. Kill fish and harmful microorganisms, improve the bottom quality of the breeding pond, filter and receive the water with an inlet net, filter and receive the water with a 60-mesh inlet net at the water level of 60cm, fertilize, and cultivate the pond water; the water depth is 1.9 ~ 2.0m, and the breeding pond is preferably an estuary Area water pond. According to the algae breeding situation, proper fertilization can be used to cultivate the pond water. Muddy bottom material is conducive to burial and overwintering of blue crabs.
