Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of aquaculture cage that prevents biological attachment, by tight cover one deck cylinder net outside breeding cage, to prevent that aquatile is attached directly on breeding cage.The simple easy operating of the present invention.
Prevent an aquaculture cage for biological attachment, comprise breeding cage and cylinder net, described cylinder net is tightly placed on breeding cage, and after having overlapped, due to the convergent force of cylinder net, two ends natural shrinking can not come off, and the mesh diameter of cylinder net is less than the mesh diameter of breeding cage.
Described cylinder net transverse elasticity is good, stretches 10～29 times that rear width is original width, meanwhile, is easy to tear.
The mesh diameter of described cylinder net is 0.3mm～15mm, according to the difference change size of mesh of breeding cage aquaculture organism and demand.
Described breeding cage is a kind of of scallop, stalwart blood clam, oyster, Cage for culture of abalone.
During use, according to the shape of breeding cage, prepare a bucket that can put down breeding cage, highly for put in bucket with breeding cage after, lower than bucket edge, be as the criterion, one section of above-mentioned cylinder net opening is enclosed within on base bucket, selvage higher than bucket along 5-20 centimetre, breeding cage is put into bucket, Jiang Tong top line of the net UNICOM breeding cage lifting rope is caught simultaneously, firmly upwards mention, cylinder net has just been enclosed within outside breeding cage, simultaneously because the effect of elastic force, cylinder net can be enclosed within comparatively closely on breeding cage and not drop, net is cut off along 5-20 centimeters under breeding cage, net just firm bundle on cage, the peak time of adhering at fouling organism, especially the peak season that fouling organism is bred and adhered to, by net on breeding cage, when adhering to peak after the past, cylinder net is torn, the aufwuch adhering to above is just removed in the lump together with cylinder net.
The utility model beneficial effect compared with prior art
The utility model arranges one deck cylinder net in breeding cage outside, can be good at preventing and treating on the etting that aquatic organism is attached to breeding cage, it is online that most aquatic organisms are attached to cylinder, by the time when adhering to after peak goes over, cylinder net is torn, and the aufwuch adhering to above is just removed in the lump together with cylinder net.Avoided the operation of switching breeding cage in order to remove biological attachment etting in prior art, saved time, laborsaving, reduced aquaculture cost simultaneously.
