A method for highly efficient shelling of Artemia eggs

Abstract

The invention discloses a method for efficiently removing shells of Artemia eggs. The commercial Artemia eggs are soaked in fresh water, then soaked in sea water and fully aerated; then the eggs are sterilized, soaked in sodium hypochlorite solution and fully aerated. When the eggs turn orange, separate the egg shells, wash the eggs to remove residual chlorine, and then soak them in an ethanol solution containing shikonin for 40‑60 minutes. After soaking, rinse with sea water to remove the residual ethanol from Artemia eggs That’s it; the present invention can further dissolve the keratin of the egg membrane after shelling the Artemia eggs, and can maintain the activity of the embryos, so that the embryos of the Artemia eggs can be fully exposed, and the early embryonic development of the Artemia eggs can be directly observed under the microscope , which has important guiding significance for the family selection of Artemia in the embryonic stage, and also for the efficient and stable hatching of Artemia eggs without pathogens, thereby providing sufficient and high-quality bait for fish and shrimp breeding and breeding, which has a good impetus to the aquatic breeding industry function and application value.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for efficiently shelling Artemia eggs. Background technique [0002] At present, the vast majority of aquatic animal seedlings require live animal baits, and Artemia is the most widely used one. Artemia eggs refer to dormant eggs produced by Artemia. There are more than 100 strains of Artemia eggs recorded in the world. The newly hatched nauplii of Artemia eggs have a large amount of yolk, and are rich in protein and fat (about 60% protein and 20% fat), and the nutrients contained in the adults are also very high, so Artemia is a fish High-quality and high-nutrition bait for seedlings and growing-up stages of shrimps, crabs, etc. According to reports, more than 85% of aquaculture animals in the world currently use Artemia as a source of bait for raising seedlings. [0003] Artemia eggshells are rich in iron lipoprotein, which cannot be digested by fish and shrimp ...

AI Technical Summary

Problems solved by technology

[0004] At present, the incubation and production technology of Artemia eggs has been in a simple and rough low-efficiency mode, resulting in the hatching rate of Artemia eggs being around 50-70% in the industry, while the hatching rate in the general 24h incubation cycle is low, so Increased production costs. In fish and shrimp breeding, the cost of Artemia eggs often accounts for 50%-70% of the production cost of the hatchery, or even higher
