Embodiment 1

[0017] Freeze the harvested eggs at -18°C for 1 month and then dry them directly; add enteric-coated capsules containing sodium peroxide 15, 16, 17, 18, 19 to the packaging can (425 g / can) , 20 capsules, 1 gram each, packaged together with worm eggs; when in use, pour worm eggs and enteric-coated capsules into the hatching pond for incubation. (Note: The raw material is Russian salt lake eggs.)

Abstract

The invention discloses an Artemia ovum hatching method with high hatchability rate which comprises the steps of, freezing the collected insect ovum, drying directly, charging capsule with chemicals into the packaging tank, packaging together with the insect ovum, the chemicals include solids capable of generating hydrogen peroxide, during the using process, the insect ovum and capsule are poured into the hatching pool for hatching. The method can substantially increase hatching rate, the quality period can be extended for over 6 months.

Description

technical field [0001] The invention relates to a method for producing feed, in particular to a method for hatching Artemia eggs. Background technique [0002] Artemia (Artemin) English name is Brine.shrimp, as the name suggests is a living in salt water, commonly known as "worm" or "shrimp". It adapts to a wide range of environments. It can survive in coastal salt pans, inland salt lakes, and alkali lakes. When the living environment deteriorates (entering winter or increasing salinity), in order to continue the population, Artemia will release eggs (commonly known as Artemia eggs). The nauplii hatched by Artemia eggs are the necessary opening bait in aquatic nursery such as fish and shrimp. The achievements of the great development of my country's shrimp farming industry are inseparable from the use of Artemia as bait. It is difficult to replace other natural baits or artificial feeds developed. Artemia eggs are easy to preserve, easy to circulate, and ready to hatch. T...
