Problems solved by technology

With the development of the aquaculture industry in recent years, the application of Artemia eggs in the production of aquatic seedlings has become more and more extensive. Although my country is a country rich in Artemia resources, it is still difficult to meet the needs of the market, so it is necessary to manually process Artemia eggs to make up for the shortage in the market, but the current common problem encountered by artemia egg production units is that the hatching rate of artemia eggs is not high, it is difficult to meet the requirements of commercial eggs at one time, and the quality of artemia eggs is not high

Embodiment 1

[0022] A finishing method for Artemia eggs, comprising the following steps:

[0023] Step (1): Soak fresh Artemia eggs twice. The first time is to put fresh Artemia eggs into saturated brine with a salinity of 240 and stir well. After the impurities are precipitated, remove the fresh eggs and put them back in clean saturated brine with a salinity of 270 and stir evenly, and then remove the fresh Artemia eggs after the impurities are precipitated; when soaking the Artemia eggs for the first time, stir once every 4 hours, and the soaking time for the first time For 24 hours, stir once every 3 hours when soaking brine eggs for the second time, and the second soaking time is 20 hours;

[0024] Step (2): put the twice-soaked Artemia eggs into a storage pool filled with saturated brine for temporary pickling, the salinity of the saturated brine is 250; during the temporary pickling, stir once every 5 hours .

[0025] Step (3): Measure the water temperature in the storage pool, and...

Abstract

The invention relates to the technical field of production of aquacultural seedings, and particularly relates to a fine processing method for an artemia cyst. The fine processing method comprises thesteps of soaking, extracting, temporarily storing, pickling, storing by refrigerating, detecting the hatching rate, slowly unfreezing, soaking, dehydrating, drying and packaging. The two big problemsproduced in the artificial processing of the artemia cyst are that the hatching rate is not high and the quality of the artemia cyst is relatively low, the quality of the artemia cyst and the hatchingrate of the artemia cyst are greatly improved by soaking and extracting twice, strictly controlling the temperature of freezing, unfreezing and refrigerating and strictly controlling the salinitythetime and the operation steps in soaking and dehydrating, so that the hatching rate of the artemia cyst meets the requirement of a commercial artemia cyst at a time as much as possible, the times for repeatedly processing the artemia cyst, whose hatching rate does not meet the requirement, are greatly reduced, so that the labor cost, the time cost and the processing cost are lowered, and the benefit of a production unit is increased.

Description

technical field [0001] The invention relates to the technical field of aquatic seed production, in particular to a method for finishing artemia eggs. Background technique [0002] As an important bait organism and a good experimental animal material, Artemia has been widely valued by people. It is rich in protein, complete in amino acid composition, and relatively high in crude fat. Among them, the unsaturated fatty acid is higher than the saturated fatty acid. The unsaturated fatty acid of eggs is 48.15%, that of shelled eggs is 54.82%, and the saturated fatty acid of shelled eggs is 1.5 times that of shelled eggs. With the development of the aquaculture industry in recent years, the application of Artemia eggs in the production of aquatic seedlings has become more and more extensive. Although my country is a country rich in Artemia resources, it is still difficult to meet the needs of the market, so it is necessary to manually process Artemia Eggs are used to make up for t...
