Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.It should be understood that following examples are only
For illustrating the utility model not for restriction the scope of the utility model.
Fig. 1 show the preferred embodiment of the utility model one be used for test the dress that fishing is degraded with fiber in marine environment
Put, it includes plastic frame 1, float 2, copper alloy mesh sheet 3, fiber fastener 5, sinker 6 and synthetic fiber rope 7.
Wherein plastic frame 1, copper alloy mesh sheet 3 and synthetic fiber rope 7 form the net cage of open top.Plastic frame 1
