钢丝网箱的附着生物主要靠潜水清除,一部分也采用混养捕食附着生物的鱼类的方法来清除。但是,混养法的报道仅见于化纤网箱的少数事例,没见到关于钢丝网箱的附着生物种类和混养法等资料。由于采用电防腐法,钢丝网箱的使用年数得以延长,故更需要相应的附着生物对策。因此,观察了(鱼師)鱼等有代表性的海水鱼养殖中钢丝网箱的附着生物,并调查了混养石鲷类时清除附着生物的效果。调查对象及方法从1978年4月开始,经过约4年的时间,调查了日本中、西部养鱼场的网箱(表 Wire mesh attachment organisms mainly by diving to clear, and some also used polyculture prey attached to the method of biological fish to clear. However, the report of polyculture was only found in a few cases of chemical fiber cages. No information was found on the attached biological species and polyculture methods of steel cages. Due to the adoption of the electric anti-corrosion law, the number of years of use of the wire mesh cages can be extended, so the corresponding biological measures are required. Therefore, we observed the attachment of steel cages in representative marine fish farming, such as fish mascot, and investigated the effect of removing attached organisms when breeding gibberette. Survey object and method From April 1978 onwards, after about 4 years of investigation in Japan, the western fish farm cage (table
