Special simulated pectoral fin fanning equipment and hatching method for artificial hatching of clownfish fertilized eggs

Abstract

The invention discloses equipment specialized for simulating flapping of pectoral fin in artificial hatching for fertilized eggs of clownfish and a hatching method. The equipment comprises a rotary shaft and a power device used for driving the rotary shaft to rotate, wherein a water inlet is formed in one end of the rotary shaft, a water outlet is formed in the other end of the rotary shaft, a water flow channel is arranged in the rotary shaft, the two ends of the water flow channel are respectively communicated with the water inlet and the water outlet, and the water outlet is in a strip shape and has the trend consistent with the axial direction of the rotary shaft. The hatching method comprises the following steps: placing a flower pot in an egg laying area of the clownfish, waiting for the clownfish to lay the fertilized eggs on the inner wall of the flower pot, preparing a set of equipment specialized for simulating the flapping of the pectoral fin in the artificial hatching for the fertilized eggs of the clownfish and mounting the equipment at a preset position; taking out the flower pot with the fertilized eggs, placing the flower pot in a fry culture vessel and putting the lower end of the rotary shaft into the flower pot, wherein the water outlet on the rotary shaft is located in an inner cavity of the flower pot; injecting water into the water inlet and starting the power device, so that flake-shaped water flow sprayed out of the water outlet sweeps over the fertilized eggs on the inner wall of the flower pot until the fertilized eggs are hatched to form fries, therefore, the survival rate of hatching for the clownfish is improved, and the manual labor intensity is lowered.

Description

technical field [0001] The invention relates to an artificial hatching technology of fertilized eggs of clownfish, in particular to a device for simulating pectoral fin fanning specially used for artificial hatching of fertilized eggs of clownfish and a hatching method using the device. Background technique [0002] With the improvement of living standards, recreational aquarium fishery represented by ornamental fish has gradually become a new fashion for household consumption, and ornamental fish farming has also developed into a large-scale global emerging industry. [0003] Although the ornamental fish industry has a huge market space and high profits, its source channels mainly rely on natural resources, which has become a bottleneck restricting its development. At present, 95% of the seedlings of seawater ornamental fish sold in the market come from wild fishing, and only 5% are artificially bred and raised. Moreover, the wild fishing method is brutal, which has caused ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a special simulated pectoral fin flapping device and hatching method for the artificial incubation of fertilized eggs of clownfish, which solves the technical problem that the fertilized eggs of clownfish cannot be hatched in a larvae culture container, improves the hatching survival rate of fertilized eggs of clownfish, and reduces artificial Nursing intensity, more significant economic benefits
