Overwintering device for whitmania pigra culture

Abstract

The invention relates to the technical field of aquaculture, and discloses an overwintering device for whitmania pigra culture. The device includes a breeding box, a box cover is hinged to an openingin the upper end of the breeding box, heating lamps are symmetrically mounted on the box cover, a light brightness regulator electrically connected to the heating lamps is mounted at the upper end ofthe box cover, fixing plates are symmetrically and fixedly connected to the opposite inner box walls of the breeding box, positioning rods are fixedly connected to the upper ends of the fixing plates,a net cage is arranged between the two fixing plates, side plates are fixedly connected to the two sides of the net cage, positioning holes are formed in the side plates, the positioning rods are sleeved with the side plates through the positioning holes, and abutting plates are symmetrically and fixedly connected to the inner cage walls of the net cage. According to the overwintering device forwhitmania pigra culture, whitmania pigra in the breeding box can be conveniently taken out, the interior of the breeding box is easy to clean, the culture environment in the breeding box is better, and culture of whitmania pigra is facilitated.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a wintering device for wide-body golden leech breeding. Background technique [0002] With the improvement of people's awareness of the value of leeches, more and more people are carrying out artificial breeding of leeches. Among them, the wide-bodied golden leech is a relatively common cultured species. The body of the wide-bodied golden leech is slightly spindle-shaped and flat, and its body contains anticoagulant substances. Diseases such as thrombosis, cerebral arteriosclerosis, and heart failure have high medical value. With the rise of the incidence rate, the market demand for wide-bodied golden leeches is increasing. When the wide-bodied golden leech survives the winter, it is necessary to use a wintering device to help the wide-bodied golden leech survive the winter. [0003] The Chinese Patent Authorization Announcement No. is CN208387633U, which discloses a wide-b...
