A nano-inflatable device for hatching eggs of Artemia

Abstract

The invention belongs to the field of aquaculture, and discloses a nanometer air inflation device used for incubation of Eubranchipus vernalis eggs. The device is characterized by comprising a PVC pipe (1), a reducing tee (2), a nanotube (3), a cylindrical sand head (4) and a hose (5), wherein the upper opening of the reducing tee (2) is connected with and arranged on the PVC pipe (1); the nanotube (3) is connected with the left opening and the right opening of the reducing tee (2) so as to form a ring shape; and the air inlet of the cylindrical sand head (4) is connected with the hose. The invention provides the nanometer air inflation device capable of improving the incubation rate of Eubranchipus vernalis eggs and reducing pollution risk brought by death of Eubranchipus vernalis eggs, so the use cost of Eubranchipus vernalis eggs is decreased, and incubation efficiency is improved. The nanometer air inflation device provided by the invention has the advantages of reasonable design, convenience and practicability.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a nano-inflatable device for hatching Artemia eggs. Background technique [0002] Artemia is also called Artemia, and its full name is Eubranchipus vernalis (Eubranchipus vernalis) brine brine shrimp. It is a small crustacean widely distributed in the world and resistant to high salt. 50‰-250‰, as an important bait organism, has been widely valued by people. The aquaculture industry, especially the seedling breeding process, has a very large demand for Artemia worms. Because the production of Artemia worms is not high, the price of Artemia eggs has always been high, and users hatch and feed them after purchasing Artemia eggs. [0003] The hatching of Artemia eggs is mainly affected by the following factors: salinity, temperature, dissolved oxygen, pH and light intensity. If any one of these factors is not up to standard, it will affect the hatchability. In orde...

If any of these factors is not up to standard, it will affect the hatching rate

In order to improve the hatching efficiency, the current common Artemia egg hatching adopts high-density hatching and uses cylindrical sand heads to inflate. In the later stage of hatching (12-24h), the dissolved oxygen in the water body gradually decreases to be lower than the dissolved oxygen required for the hatching of Artemia eggs. In addition, the inflated water flow of the cylindrical sand head is small, and an effective water circulation circle cannot be formed. Most of the eggs cannot be released from the light on the water surface at the bottom of the bucket, so that they cannot hatch, resulting in a low hatching rate of Artemia eggs, which reduces the hatching efficiency and hatching output. Increased costs; and the unhatchable artemia eggs become dead eggs, which are brought into the breeding pond, causing pathogenic pollution
