据记载,日本在大政年间(1818—1929年)就开始在北海道放流鲍鱼。但是,科学地搞清放流效果则是在1935年以后,那时是放流成贝和天然苗种。人工苗种的生产和放流是从1965年前后开始的。到1985年,一处设施已经可以生产几十万乃至几百万稚贝。在全国37处县级规模的栽培渔业中心中,有31处培育鲍鱼苗种,如果包括市和渔协的设施,1981年大致生产稚贝1930万个,其中约1120万个用于放流。据悉,放流贝在渔获物中所占比例已达30％以上(井上等1985)。现根据有关资料综述如下:
According to records, during the Great Administration years (1818-1929), Japan began to release abalone in Hokkaido. However, scientifically clarifying the effects of discharge is after 1935, when it was released into Chengbei and natural seed. The production and release of artificial seed began around 1965. By 1985, a facility could already produce hundreds of thousands or even millions of juveniles. Of the 37 county-scale cultivation fisheries centers in the country, 31 cultivated abalone seedlings. In 1981, about 19.3 million juveniles were produced, including about 11.2 million for releasing abalone. It is reported that the release of the flowering shellfish in the proportion of catch has reached more than 30% (Inoue 1985). Now based on the information summarized as follows:
