Description

Krill cleaning and filtering device for feeding zebra fish in laboratory

Technical Field

The utility model relates to an auxiliary device that feeds the zebra fish in the laboratory, concretely relates to krill washs filter equipment is fed to the zebra fish in laboratory.

Background

Zebra fish is a mature high-throughput screening model organism at present, has tissue organs and systems similar to human, and has genes and signal paths which are highly conserved with human. Meanwhile, the method is also praised as: "mice in water". Zebra fish is a omnivorous animal and brine shrimp is one of the most favored foods for zebra fish. The brine shrimp contains more protein and fat, is favorable for the growth of the zebra fish, and is very suitable for feeding the zebra fish because the brine shrimp can carry little parasites or bacteria compared with other live baits. The brine shrimp which is commercially available is usually dormant eggs, the brine is required to be incubated for more than 12 hours in water with the salt content of 10-15g/L and the temperature of 25-30 ℃ in a boiling state by pumping, and then the brine shrimp is fed to the zebra fish for eating through the steps of filtering shrimp shells, cleaning shrimp bodies to show the salt content and the like.

Because the brine is very small in volume, brine is required to be used for pressurized incubation after the brine is purchased, the shrimp shells are filtered, then the high-concentration salt on the shrimp meat is cleaned by clear water, and then the shrimp shells are put into a fish tank of each zebra fish by a dropper. The current cleaning tool for the shelled brine shrimp is a self-made small compact fishing net, the water leakage hole of the fishing net is smaller than the volume of brine shrimp, one scoop of brine shrimp is cleaned in a container filled with water each time, and the high-concentration salt on the shrimp meat is generally cleaned in real time for multiple times, and multiple water changing operations are needed in the middle.
