[0002] Zebrafish is the third largest vertebrate model organism after mice and rats, and has been widely used in many fields such as developmental biology, genetics, basic medicine, pharmacology, toxicology, drug development, and ecological and environmental evaluation.
[0003] However, in the current laboratory zebrafish breeding process, the Artemia worms are generally fed directly with a plastic straw. The amount is difficult to control and can easily lead to overfeeding, which will cause the remaining Artemia worms to clog the water outlet of the breeding tank and pollute the water quality. Feeding too little will cause individual zebrafish to be poorly developed and have inconsistent sizes. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] (1) The utility model uses the cooperation of the sealing block, the conical hole, the sealing ball, the first spring and the connecting tube to prevent the artemia liquid in the storage bottle from being discharged from the vertical tube after being pumped into the vertical tube. At the same time, when the user presses and releases the liquid pumping bracket, the liquid pumping bracket can lift a specified amount of artemia liquid to the catheter and discharge it through the catheter. At this time, the feeding instrument can discharge the artemia liquid in a quantitative manner, thereby preventing the water outlet from being blocked and the water quality from being polluted due to excessive feeding of artemia liquid, or preventing the individual zebrafish from being poorly developed and having inconsistent sizes due to insufficient feeding.

When the Artemia liquid in the storage bottle is stratified, the Artemia liquid can be evenly shaken by moving the push-pull ring up and down, thereby making the feeding device more convenient to use.

Through the cooperation of the sliding sleeve 105 and the column 104, the sealing circular plate 103 can only move up and down in the threaded barrel 102. The bottom of the sliding sleeve 105 and the upper surface of the sealing circular plate 103 are fixedly connected with a second spring 107.
