Abstract
The invention discloses a carp nest, which is characterized by comprising a peripheral frame and a net arranged on the frame surface, wherein the frame is a cuboid, and is formed by splicing hollow tubes; a cavity of the frame is filled with sand soil; two opposite surfaces of the frame in the height direction are hollow, the other surfaces of the frame are provided with two-layer nets; except the top two-layer net, other two-layer nets are externally bound with net cloth; and when the net cloth is bound, the net cloth is folded in half, and is bound onto the net along the folding line. The carp nest is firm in structure, can keep water in a hatching pond clean, is high in production inducing capacity, adhesion, air permeability and light transmission, can improve fertilization and hatching rates, is time-saving and labor-saving in recovery, can reduce the loss of fries, is durable, and convenient to clean, disinfect and store, can be repeatedly used, saves financial resources and human resources, can eliminate adverse effects of a material of the traditional carp nest on germ cell hatching and fry survival and growth of carp, and has a good application prospect.
