由于资源枯竭,在北海道沿岸开展了各种各样栽培渔业的试验.道工技术中心开发电栅栏以防止外逃和敌害生物进入的“海洋牧场系统”养殖鲍鱼.在人工鱼礁的周围通电,形成屏障区,能使鲍鱼及侵袭它的海盘车、章鱼等因电感而受阻.对鲍鱼的生长情况由电视摄像机进行24小时监视.同以往的网箱和笼养进行比较,认为可以减少波浪等的影响,提高成活率.牧场是用厚40厘米的钢筋混凝土围成,中间是2米正方形、高1.8米的钢筋构成的养成床,养殖2500个鲍鱼.在养成床周围3
Due to depletion of resources, a wide range of experiments were carried out on the coast of Hokkaido to cultivate fisheries, and the TDC developed a “sea ranch system” for the construction of electric fencing to prevent the escape of flea and predatory organisms. "Around the artificial reefs Electricity, the formation of a barrier zone, abalone and the sea its hit the car, octopus and other obstruction due to the growth of abalone by the television camera for 24-hour surveillance with the previous cage and cage comparison, that can Reduce the impact of waves, etc., to improve the survival rate. Ranch is surrounded by 40 cm thick reinforced concrete, the middle is 2 meters square, 1.8 meters high steel to form a bed, breeding 2500 abalone.
