Abstract

The utility model discloses a novel foldable parent shellfish culture net cage, and belongs to the technical field of aquiculture. The novel foldable parent shellfish culture net cage comprises two square frames composed of hollow sealed PVC (polyvinyl chloride) pipes, a rectangular polyethylene mesh, a rectangular rigid plastic screen and floating balls. The novel foldable parent shellfish culture net cage is characterized in that the periphery of the two PVC square frames is connected together through the rectangular polyethylene mesh; the rectangular rigid plastic screen is arranged on the lower PVC square frame to form the net cage; and the floating balls are tied at four corners of the upper PVC square frame. The novel foldable parent shellfish culture net cage has the advantages that as the two square frames are composed of the hollow sealed PVC pipes, the frames are conveniently manufactured without welding, rustless and light, the consumption of the floating balls is reduced and the cost is lowered; the net cage can be folded when not in use, thus saving space and facilitating placement and transportation; and the rigid plastic screen is adopted on the bottom of the net cage so that parent shellfish can be uniformly distributed, thus improving the survival rate and promoting development of the parent shellfish.

Description

A kind of novel foldable shellfish parent is cultivated net cage

Technical field

The utility model belongs to technical field of aquaculture, and particularly a kind of novel foldable shellfish parent is cultivated net cage.

Background technology

It is the key link of shellfish seed rearing that the parent shellfish is cultivated, for shellfish is formed the important foundation that the seed that healthy high-quality is provided is the stable high yield of shellfish culture industry, the unsteady net cage that the close shellfish of present cultivation is used is generally all made with steel bar framework and polyethylene etting, steel bar framework needs welding, make trouble, get rusty easily, before using every year, all need rust cleaning, heavy many with buoyancy, the cost height; Net cage is in time spent not, and it is big to take up room, place and transportation inconvenient; The polyethylene etting is used in the bottom, easily forms the string bag, and close shellfish is piled up and causes death.

Summary of the invention

Technical assignment of the present utility model is not enough at above prior art and a kind of novel foldable shellfish parent cultivation net cage that provide.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel foldable shellfish parent is cultivated net cage, comprise two the square polyethylene etting of square frame, a block length, a rectangle duroplasts screen cloth and ball floats that constitute by the pvc pipe of hollow sealing, it is characterized by: described culture apparatus utilizes rectangle polyethylene etting to connect together around two PVC square frames, rectangle duroplasts screen cloth is installed in down net cage of formation on the surface and PVC square frame, and ball float is tied up to four jiaos on surface and PVC square frame.

This utility model has following beneficial effect: it is that pvc pipe by hollow sealing constitutes that novel foldable shellfish parent is cultivated two square frames of net cage, easy to make need not the welding, and non-corrosive, material gently reduce the ball float consumption, and cost is low; Net cage can be folded up in time spent not, saved the space, placed and convenient transportation; The duroplasts screen cloth is used in the bottom, and close shellfish is distributed uniformly, improves survival rate, promotes close shellfish to grow.
