AI Technical Summary
In existing technologies, crucian carp eggs are difficult to fix during microinjection, which increases the difficulty of injection, causes frequent damage to the eggs, and results in low dispersion and positioning efficiency, thus reducing the hatching success rate and overall injection efficiency.
A device comprising a base, a microinjector, a turntable, a fish egg dispersion component, and a cloth component was designed. The turntable is driven to rotate 90 degrees by the rotating component. Combined with water flow and negative pressure adsorption, the continuous and automatic operation of dispersing and fixing crucian carp eggs and microinjection is realized.
It improves the efficiency of crucian carp egg dispersion and microinjection, ensures the stability of egg position, reduces damage, and improves hatching success rate and overall injection efficiency.
