Embodiment 1

[0016] The high-yield culture method of crab comprises the steps:

[0017] (1) Choose a pond with an area of ​​1.5 mu, a width of 10 meters, and a length of 70 meters. Lay anti-escape tempered 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 220 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 released in March, and bait is put in every morning and evening, and the amount of each feeding is 7% 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 made of the following raw materials according to the weight Composition: 180 parts of bean cake powder, 70 parts of corn flour, ...

Abstract

The invention provides a high-yield cultivation method of crabs. The high-yield cultivation method comprises the steps of selecting a pond and laying anti-escape toughened glass at the four sides of the pond, performing pond cleaning through a dry process by use of quick lime, injecting water until the water depth is in the range of 0.2-0.8m 8 days later after pond cleaning and applying a base fertilizer for fertilizing the water, putting in juvenile crabs in March and putting in a bait at morning and evening every day, performing pond inspection every day to remove frogs, snakes and rates going into the pond, injecting fresh water every week, increasing the depth of water in the pond to the range of 1.1-1.3m in summer, and catching in October, wherein 180000-200000 juvenile crabs, 60-80 crabs per kilometer, are put in per mu; the bait is prepared from such raw materials as 150-200 parts of bean cake meal, 50-80 parts of corn flour, 10-12 parts of vegetable oil, 0.1-0.5 part of vitamin B, 0.1-0.2 part of CaCl2, 5-6 parts of radix scrophulariae, 1-2 parts of fructus forsythia, 1-2 parts of semen cassia, 1-2 parts of Chinese olive and 50-60 parts of water.

Description

technical field [0001] The invention relates to the field of cultivation, in particular to a method for cultivating crabs. Background technique [0002] Crab (páng xiè): Animalia, Arthropoda, Crustacea, Decapod order, Reptilia suborder. Crabs are crustaceans whose bodies are protected by a hard shell. Crabs breathe through gills. In terms of biological taxonomy, crabs and shrimps, lobsters, and hermit crabs are considered to be the same kind of animals. 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 breeding process of crabs, because the nutrition of crab feed is not comprehensive en...
