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...

Most species of crabs live in or near the sea, while some live in freshwater or on land. They rely on the female crab to give birth to small crabs, and each time the female crab will lay a lot of eggs, the number can reach more than millions. Crabs rely on the geomagnetic field to determine direction. China has a long history of eating crabs, which are recorded in "Yi Zhou Shu Wu Hui Jie" and "Zhou Li Tian Guan Bu Ren". [0003] In the cultivation process of crabs, since the cultivation time is from early March to Octob...
