Embodiment Construction

[0038] A culture method for improving the output of crab and crab paste, comprising the steps of:

[0039] (1) Construction of breeding pond: build a breeding pond with an area of ​​1-3 mu. There are sun-drying balconies around the breeding pond, and a fence is placed on the outermost layer of the breeding pond. The depth of the breeding pond is 1.2-1.5m. Lay pond mud with a thickness of 10-15cm on the bottom and expose it to the sun for 4-6 days before use;

[0040] (2) Construction of aquaculture environment: first pour 15-25cm deep pool water into the aquaculture pond, set up multiple aeration pipes around the pool wall that is flush with the water surface of the pool, and the aeration pipes are connected to an external aerator. At this time, plant aquatic plants in the pool and put in water earthworms. After 3-5 days, add water until the water depth of the pool is 40-50 cm, keep the oxygen content in the pool water at 5-6 mg / L, and add water again after 5-7 days until the ...

Abstract

The invention discloses a culture method for increasing the yield of crab cream. The culture method comprises the following steps of 1 culture pond building, 2 culture environment constructing, 3 crab stocking and 4 daily managing. According to the culture method, through scientific culture pond environment setting, bait putting and daily managing operation, the total yield of crabs is increased by 20%-30%, the survival rate of the crabs is increased by 15%-20%, the adult male crab cream yield is increased by 10%-13%, and the cultured crabs are large in size, more and compact in crab cream and delicious in meat and have the high market competitiveness.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a breeding method for increasing the output of crab and crab paste.
