Special culturing salt for increasing hatchability of brine shrimp eggs

Abstract

The invention discloses special culturing salt for increasing the hatchability of brine shrimp eggs. The incubation of the brine shrimp eggs is performed in an incubation culture medium, different substances are added to the incubation culture medium and are mixed to prepare special salt in the solid powder manner according to the following corresponding percentage by weight: 85-90% of sodium chloride, 3-5% of magnesium chloride, 2-4% of magnesium sulphate, 2-3% of calcium chloride, 2-3% of potassium chloride, 1-2% of sodium bicarbonate, 0.2-0.8% of sodium carbonate, and 0.1-0.15% of calcium peroxide. The concentration of the incubation culture medium is 28-35 g / L, and the density of the brine shrimp eggs in the incubation culture medium is less than or equal to 3 g of dried brine shrimp eggs per liter of the incubation culture medium. The method not only guarantees the salinity desired by the incubation of the brine shrimp eggs, but also does not cause a side effect on the incubation of the brine shrimp eggs; most important of all, varied component salt substances and an appropriate amount of the calcium peroxide can destroy the diapause eggs in the brine shrimp eggs, and the brine shrimp eggs are promoted to incubate brine shrimp nauplius which can freely go, so that the hatchability of the brine shrimp eggs reaches 80% or above.

Description

Technical field: [0001] The invention relates to a culture-specific salt for promoting the hatching of Artemia eggs, in particular to a method for improving the hatching rate of Artemia eggs. Background technique: [0002] Artemia (BrineShrimp), also known as saltwater Artemia, is a creature that lives in salt water. It is also called salt worm or brine shrimp in Chinese folk. my country's coastal salt fields have an area of ​​345,000 hectares, and there are nearly a thousand large and medium-sized salt lakes in the inland. In these vast waters, there are very rich artemia resources. Artemia has been widely valued as an important bait organism and a good experimental animal material because of its rich nutrition. When the living environment deteriorates (such as temperature drops and salinity increases), in order to continue the population, Artemia will release eggs, commonly known as "Artemia eggs". Because Artemia eggs can be freeze-dried, easy to store, and can be hatc...

AI Technical Summary

Problems solved by technology

At present, most of them directly use hydrogen peroxide solution or add oxidase to improve the hatching rate of Artemia eggs. It takes a lot of experiments to determine the appropriate concentration ratio, and the time for adding is also strict, and the follow-up treatment is cumbersome. The addition of will cause the pH of the hatching environment to be too high, which may lead to the death of Artemia nauplii, and it is not generally applicable to all kinds of Artemia eggs
