CN105660537A - Fairy shrimp egg hatching method - Google Patents

Abstract

The invention relates to a fairy shrimp egg hatching method. The method comprises the following steps: (1) fairy shrimp eggs are soaked in a sodium hydroxide solution with a concentration of 0.1-0.3g/m<3>, wherein a soaking time is 60-72h; (2) the fairy shrimp eggs are fetched from the sodium hydroxide solution, and are soaked in clear water with a temperature controlled at 10-20 DEG C until all hatched, such that fairy shrimp larvae and shells are obtained; (3) the fairy shrimp larvae are separated from the shells; (4) the fairy shrimp larvae are soaked in clear water with a temperature controlled at 5-10 DEG C; and (5) the hatching process is finished. The method provided by the invention has the advantages of simple method, easy implementation, and high hatching rate. With the method, yield is improved, and production cost is saved.

Description

A kind of hatching method of brine shrimp eggs

Technical field

The present invention relates to the hatching method of a kind of Macrobrachium rosenbergii feedstuff, particularly relate to the hatching method of a kind of brine shrimp eggs.

Background technology

At present, most aquatic product animal raise seedlings are required for animality live bait, and it is a kind of that fairy shrimp is. Along with the breakthrough of the extensive artificial breeding technique of new, special products of famous brands, of extra fine quality aquatic animal, the demand of animality live bait is increasing, therefore, how to ensure that the incubation rate of fairy shrimp and productivity seem particularly important, improve the economic benefit of enterprise.

Summary of the invention

The present invention is to solve that problem above provides a method that simply, implements easily, incubation rate is high, improve productivity, save the hatching method of the brine shrimp eggs of production cost.

The technical scheme is that described hatching method comprises the steps:

1) first, brine shrimp eggs is put in sodium hydroxide solution and soak, described concentration of sodium hydroxide solution 0.1-0.3g/m³, described brine shrimp eggs soak time is 60-72 hour;

2) secondly, being taken out by brine shrimp eggs from sodium hydroxide solution, put in clear water and soak, clear water temperature controls at 10-20 DEG C, until brine shrimp eggs all hatches, obtains fairy shrimp larva and housing;

3) then, fairy shrimp larva is separated with housing;

4) last, fairy shrimp larva is reentered in clear water and soaks, clear water temperature controls at 5-10 DEG C;

5) complete.

The inventive method is simple, implement easily, incubation rate is high, improve productivity, save production cost.

Detailed description of the invention
