Problems solved by technology

The shells shed by Artemia are rich in Ca 2+ , can effectively supplement the problem of calcium deficiency in young crabs. The Artemia bred by this method is the favorite food of the crab seedlings, which increases the immunity of the crab seedlings, improves the survival rate, and the quality of the crabs is good. Simple and convenient, it solves the technical problems of Artemia breeding and reproduction

Embodiment 1

[0019] Step 1: Screen the Artemia eggs, and screen out the shriveled eggs that cannot hatch. Before hatching, soak the Artemia eggs in sodium hypochlorite (5ppm) for 15-20 minutes, and wash the remaining sodium hypochlorite in the eggs with fresh water after soaking.

[0020] Step 2: Disinfect the hatching bucket, inject water with trichloride (10ppm disinfection, and gas for 12h) 24 hours in advance, raise the water temperature to between 26°C and 30°C after water injection, and install air chambers in the hatching barrel, the more The better, to prevent the eggs from sinking to the bottom, sprinkle soda (no adverse effects were found in excess of soda), after 1 hour of gas storm, sprinkle EDTA (3ppm), at this time you can release the eggs (smell the water before releasing the eggs) The smell of chlorine, if there is a gas explosion, the insect eggs can be released).

Abstract

The invention discloses an ecological breeding breeding method for baiting fairy shrimps capable of increasing the yield of juvenile crabs. Shells removed from the fairy shrimps contain rich Ca < 2 + > and can effectively solve the problem that the juvenile crabs lack calcium, the fairy shrimps bred through the method are fond of the juvenile crabs, the immunity of the juvenile crabs is improved, the survival rate is increased, the crabs are good in quality, the fairy shrimps can be bred and propagated on a large scale, operation is easy and convenient, and the technical problem of fairy shrimp breeding and propagating is solved. Vitamins are fed to the fairy shrimps according to the phagocytic characteristic of the fairy shrimps, then the juvenile crabs are fed, most of the vitamins are directly absorbed by the juvenile crabs, secondary transformation is avoided, after the crab larvae eat the high-quality fairy shrimps, the physique is enhanced, the survival rate of the larvae is increased from 50%-55% to 80%-90%, and therefore the breeding benefits of the crabs are increased.

Description

technical field [0001] The invention relates to a breeding method for bait of crab seedlings, in particular to an ecological breeding method of Artemia bait which can increase the production of crab seedlings. Background technique [0002] In my country, the fresh and tender meat of crabs has become a popular and popular table delicacy, especially hairy crabs, such as Yancheng Dazong Lake hairy crabs, Gucheng Lake hairy crabs, Yangcheng Lake hairy crabs, etc., are well-known in China. However, the output of crabs has not been high, and death due to disease is the main reason, and the death of juvenile crabs is the direct cause of the difficulty in increasing production. Among them, when crabs are in the transition from the first stage of peeling to the second stage of juvenile crabs, the crabs at this time eat Fewer crabs lead to poor resistance and are prone to death. Therefore, to enhance the immunity of young crabs during this period, it is necessary to feed nutritious ba...
