Embodiment 1

[0016] A method for cultivating crabs, comprising the steps of:

[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 0.2-0.8 meters after clearing the pond for 8 days, and apply base fertilizer to fertilize the water quality; the base fertilizer is chicken manure, and the application rate is 200 -250 kg / mu. Water peanuts or dogtail grass are transplanted in the pond, covering about 50-70% of the entire water surface.

[0019] (3) Put crab seedlings in March, and put granular bait in the morning and evening every day, and the amount of feeding each time is 6-8% of the weight of crabs; put 180,000-200,000 buckle crab seedlings at 60-80 / catties per mu.

[0020] (4) Patrol the pond every day to remove the frogs, snakes and rodents entering the pond, add new water onc...

Abstract

The invention provides a crab breeding method. The crab breeding method comprises the following steps of selecting a pond and laying escape-preventing tempered glass around the pond; adopting a quick lime drying method to clear the pond, wherein the quick lime using amount is 150 kilograms / mu, and water is added into the pond till the depth reaches 0.2 m-0.8 m after the pond is cleared for 8 days; applying a base fertilizer to improve water quality; putting juvenile crabs into the pond at March and throwing bait particles into the pond in the morning and evening every day, wherein the bait amount each time is 6-8% of crab weight; putting 180000-20000 juvenile crabs per mu, wherein every 60 to 80 crabs weigh 1 / 2 kilogram; patrolling the pond and clearing frogs, snakes and rats entered the pond every day, and adding fresh water per week, wherein the water depth of the pond is increased to be 1.1 m-1.3 m in summer; catching the crabs. By means of the crab breeding method, crab yield is high.

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 existing crab breeding method, crabs escape easily, clear ponds are not thorough, and...
