Embodiment 1

[0016] The method for cultivating crabs comprises the steps:

[0017] (1) Select a pond with an area of ​​1-2 mu, a width of 8-12 meters, and a length of 60-100 meters, and lay anti-escape toughened glass around the pond;

[0018] (2) Use quicklime dry method to clear the pond, the dosage is 150 kg / mu, add water to the depth of 0.5 meters after clearing the pond for 8 days, and apply base fertilizer to improve the water quality; the base fertilizer is chicken manure, and the application rate is 250 kg / mu. Water peanuts or dogtail grass are transplanted in the pond, covering about 60% of the entire water surface.

[0019] (3) Crab seedlings are placed in early April, and bait is put in every morning and evening, and the amount of feeding each time is 6-8% of the weight of the crabs; 180,000-200,000 buckle crab seedlings of 60-80 / catties are put in per mu; the bait is prepared by The composition of the following parts by weight: 55 parts of small fish, 45 parts of pumpkin, 30 pa...
