Artificial propagation and spawning device for Schizothorax spp.

Abstract

An artificial propagation and spawning device for Schizothorax spp. comprises a support plate; a plurality of vertical sliding grooves are formed in the top surface of the support plate, and sliding blocks are respectively arranged in the sliding grooves; the top surfaces of the sliding blocks are respectively hinged to the bottom ends of rocking rods, and the bottom surfaces of the sliding blocksare respectively connected with the inner walls of the bottom surfaces of the corresponding sliding grooves through springs; a hatching box with an open top surface is arranged above the support plate, and the top ends of the rocking rods are hinged to four corners of the bottom surface of the hatching box respectively; the top surface of a sector gear is fixedly mounted in the middle of the bottom surface of the hatching box; the top surface of the support plate is provided with a motor through a bracket, and the outer periphery of an output shaft of the motor is fixedly fitted with the inner circle of a gear; and the gear is meshed with the sector gear. Dead eggs are regularly removed through the hatching box and a dead egg removing device, the dead eggs in the hatching box can be basically discharged through periodic operation of the dead egg removing device, the pollution of the dead eggs to a hatching liquid is avoided, the purity of the hatching liquid is guaranteed, the hatching condition of manual propagation is further guaranteed, and manually clearing the dead eggs is not required so that the labor cost is saved.

Description

technical field [0001] The invention belongs to the field of fish breeding equipment, in particular to an artificial breeding and spawning device for Schizothorax. Background technique [0002] Schizothorax is deeply loved by consumers because of its tender meat and delicious meat taste. However, wild Schizothorax is affected by factors such as long breeding cycle and external environmental influences. The natural population is small and cannot reach consumers. According to the needs of use, artificial reproduction can increase the production of Schizothorax while protecting fish resources, which is conducive to increasing the income of farmers. However, there are few breeding devices suitable for Schizothorax, and the breeding devices cannot be effectively simulated. The wild breeding environment of Schizothorax makes the output of Schizothorax not high. During the breeding process of Schizothorax, dead eggs cannot be removed in time. If the dead eggs are placed in the hatc...
