Problems solved by technology

[0002] Artemia is currently the fresh bait for more than 85% of aquaculture animal seedlings in the world, and Artemia has many different geographical strains, and the genetic characteristics and production performance of Artemia eggs of each strain are different. The rapid development of the artemia industry has greatly promoted the development and utilization of artemia resources around the world. However, after the artemia eggs of these strains are processed into artemia egg products, the hatching rate of artemia eggs will decline rapidly in the short term. Although the resources of Artemia eggs are very rich, most of them are located in salt lakes in alpine regions, where there is a large amount and low hatching rate. Therefore, most of the Artemia eggs produced in these salt lakes cannot be well utilized. At present, in Northwest China There are at least tens of thousands of tons of artemia eggs with low hatching rate accumulated and discarded in the region, and there are also large quantities of newly caught low hatching rate and dead eggs produced every year. These accumulated and abandoned Artemia eggs with low hatching rate It has not been well utilized so far. Unhatched Artemia eggs and dead eggs cannot be directly fed and used for seedling cultivation. However, in the process of raising aquatic products, because the hatched egg shells and Artemia larvae are mixed together, seedlings Eating egg shells can easily cause indigestion and affect health. Secondly, egg shells settle in the nursery pond and pollute the water quality.

Abstract

The open-mouthed bait for raising aquatic fry consists of shelled brine shrimp egg, alginate jelly, gelatin, ass-hide gelatin, lecithin, unsaturated fatty acid, fish meal and plant protein. Brine shrimp egg as the main material contains rich amino acids, lecithin, lipoid and other nutritive components and is fond for fish, shrimp and crab. The bait is produced through created technological process and the bait microcapsule is water insoluble, enable to float in water, and easy to digest by aquatic fry.
