Abstract

The invention discloses a slope type schizothorax taliensis artificial propagation spawning device and belongs to the technical field of schizothorax taliensis artificial propagation. The device comprises a spawning bed and a water diversion pipe. The spawning bed comprises impact slopes, side baffles, water baffles, rest platforms and supports. The rest platforms are sequentially arranged in a stepped mode from top to bottom. The rest platforms are connected through the inclined impact slopes. The side baffles are arranged on the two sides of the rest platforms and the two sides of the impact slopes. The water baffles are arranged at the front ends of the rest platforms. The rest platforms are sequentially placed on the supports from bottom to top. The spawning bed is provided with obstacles capable of rubbing with schizothorax taliensis to stimulate the schizothorax taliensis to spawn. The water diversion pipe is arranged above the uppermost rest platform. According to the device, conditions suitable for schizothorax taliensis spawning are created in a fish pond, the schizothorax taliensis is effectively stimulated to spawn and discharge seminal fluid, and meanwhile the sperm and egg binding efficiency is improved.

Description

technical field [0001] The invention relates to a slope type anti-wave fish artificial breeding and spawning device, which belongs to the technical field of anti-wave fish artificial reproduction. Background technique [0002] Kanglang fish, whose scientific name is Chilang white fish, belongs to Cypriniformes Cyprinidae whitefish genus, and ranks first among the top ten rare native fish in Yunnan Province. Wild Kanglang fish only grows in Fuxian Lake in Yunnan Province. At present, due to overfishing and species invasion, the population of wild anti-wave fish has declined sharply. Because the anti-wave fish has extremely strict requirements on the growth environment and it is quite difficult to raise the anti-wave fish artificially, the anti-wave fish was once on the verge of extinction. [0003] In the process of artificial anti-wave fish breeding, ensuring the smooth spawning of anti-wave fish and efficient fertilization of fish eggs is the key to successful reproduction...
