Description

Separator of artemia hatching

Technical Field

The utility model belongs to the technical field of the artemia are bred, especially, relate to a separator of artemia hatching.

Background

Artemia, also known as artemia salina, is a small crustacean, and has been widely regarded by people as an important bait organism and a good experimental animal material. Larvae hatched from eggs have a large amount of egg yolk and are rich in protein and fat, so artemia are excellent feeds for larvae and adults of fish, shrimp, crab, and the like. It is reported that more than 85% of aquaculture animals in the world are raised with artemia as a source of feed.

The most common mode in aquaculture today is to obtain larvae by artificial incubation of resting eggs of artemia, which leave egg shells after incubation. Because the egg shell is provided with bacteria, fungi and fungus spores and is not easy to digest, water pollution can be caused after the egg shell is thrown into a nursery pond, and fish larvae can cause gastrointestinal obstruction and die after eating the egg shell, the incubated artemia larvae and the egg shell are necessary to be separated.

At present, people use gravity separation, hatched larvae sink to the bottom of a container, and egg shells float on the water surface. After incubation is finished, a valve at the lower part of the container is opened, and incubated artemia are discharged out of the container, so that the aim of separating worm eggs is fulfilled. The method is only suitable for separating a small amount of larvae from egg shells, the separation time is too long, the water can be drained after the separation is not noticed for a little, a large amount of egg shells are collected, secondary separation is needed, and unnecessary troubles are brought; and if the manual net fishing is adopted, the workload is large and the labor intensity is high.
