The present application relates to loach breeding feeding technology field, specifically to a kind of loach breeding equipment, including breeding net cage, the breeding net cage periphery is equipped with polyethylene mesh cloth, detachably connected with mounting plate on the top of breeding net cage, mounting plate top surface is connected with storage box by support frame, one-way rotating turnover plate is connected on the storage box, torsional spring is equipped between turnover plate and storage box, vertically connected with material guide pipe in the form of through on the mounting plate, material guide pipe upper end portion is communicated with storage box inner cavity, the material guide pipe lower end extends into breeding net cage inner cavity, the material guide pipe lower end is equipped with even distribution mechanism, quantitative feeding mechanism is equipped in the storage box, by even distribution mechanism and quantitative feeding mechanism, feed can penetrate water hyacinth or water morning glory cover layer, directly, evenly sent to water, significantly reduce the problem that feed is intercepted or floats waste by floating aquatic plants, improve feeding efficiency and loach feeding uniformity.

The invention discloses selenium-enriched loach breeding feeding equipment and relates to the technical field of loach breeding, the selenium-enriched loach breeding feeding equipment comprises a supporting frame and a storage shell arranged outside the supporting frame, a rotating shaft is rotatably mounted at the top of the storage shell, and the rotating shaft penetrates through the storage shell and extends into the storage shell; and a synchronous wheel is fixedly installed at the top end of the rotating shaft, a synchronous belt is installed on the outer surface of the synchronous wheel in a transmission mode, a distributing mechanism is installed at the bottom end of the rotating shaft, and a feeding mechanism is installed at the bottom of the outer surface of the storage shell. According to the selenium-enriched loach breeding and feeding equipment, feed is continuously pushed through the spiral blades, the problems of blockage and the like caused by feed accumulation are prevented, the feeding mechanism is matched with the distributing mechanism, the selenium-enriched feed is uniformly dispersed and fed into the breeding pond, local oversaturation or hunger in the breeding pond is effectively avoided, uniform growth of loaches is facilitated, and the breeding efficiency is improved. The breeding quality is improved.

The application discloses a loach gender-specific SNP marker and a genetic gender identification method, and belongs to the technical field of fish genetic breeding. The loach gender-specific SNP marker is screened through whole genome resequencing and GWAS analysis; the genetic gender identification method of the loach is based on designing specific primers for the SNP marker, taking loach genomic DNA as a template, and obtaining SNP typing of the individual through PCR amplification and Sanger sequencing, wherein the homozygous type is female, and the heterozygous type is male. The application can accurately identify the genetic gender of the individual, and can screen out pseudo-male fish, pseudo-female fish and the like obtained through artificial induction, and can identify the gender in the early individual development stage, and has the advantages of minimizing damage to the tested individual, not affecting survival and the like. The application has important application value in parent gender identification in the gender control breeding of the loach.

The application discloses a loach breeding net cage and a breeding method thereof, which comprises a net cage body, an anti-escape part is fixedly connected to one side of an opening of the top of the net cage body, at least one adjusting rod is arranged on each of opposite sides of the net cage body, the net cage body is movably arranged at the inner ring part of a floating bed through cooperation of the adjusting rod and a limiting part, and the floating bed is slidably arranged on a plurality of positioning rods. Through cooperation of the floating bed and the positioning rods, the net cage body can float up with the water level rising on the floating bed, so that the net cage body is prevented from being submerged and the loaches in the net cage body are prevented from escaping and causing loss of breeding cost; the lifting distance of the net cage body on the floating bed is controlled through cooperation of the adjusting rod and the limiting part; and meanwhile, through cooperation of the anti-escape part, the loaches in the net cage body are prevented from being captured by birds that prey on fish, so that the breeding effect is improved.
