日本的鲍资源增殖手段是以苗种的放流增殖为主。放流场一般选在水质澄清、潮流通畅、盐度不低于31‰、冬季水温不低于2℃、饵料海藻生长繁茂的岩礁海区。苗种放流规格大多控制在3厘米左右,回捕率可达30%。放流后对放流场进行定期定点调查的内容包括:放流贝的捕获数、年龄组成、移动距离、死壳数与壳长、被害情况等,再据以推算其回捕率、存活率、生长量、移动范围等,以推断放流效果。通过移植、增殖的方法开发和造成新的鲍资源渔场,也是较有效的增殖手段之一。
Japan’s abalone resources proliferation means to seed multiplication and proliferation based. Put the flow field generally selected in water quality clarification, tidal flow, salinity of not less than 31 ‰, winter water temperature of not less than 2 ℃, the growth of algae feed lush sea reefs. Most of the seed release standard control in about 3 cm, the recovery rate of up to 30%. After the release of the release of the flow field regularly sentinel surveys include: the number of catfish released, the age of the composition, the moving distance, the number of dead shell and shell length, the victim situation, and then calculate the capture rate, survival rate, growth , Moving range, etc., to deduce the discharge effect. One of the more effective means of proliferation is to develop and create a new abalone resource fishery by transplantation and multiplication.
