To reuse the garbage fishing gears effectively to the other fisheries production means is the one of rational measures based on the zero-emission concept. This research has aimed to check the ability of regenerated rope with refused gill-net from amiylane material to kelp cultivation facilities.
By the results of some field tests and stochastic analysis, a large individual kelp grew more abundantly on the regenerated rope of gill-net (GR) than the polyethylene rope (PR), which is widely used for cultivation in Japan. The average force to detach kelp from GR comes up to 6.8kg in comparison with the case of PR by 4.6kg. Through the tensile test in a site, the exfoliation probabilities in typical three portions on a kelp have showed the sticking capacity onto GR surpassed PR. Also, kelp on GR has not been easily broken out from a cultivation rope rather than PR.
