在福岛县，自1996年以来，每年都有100万条孵化饲养的青少年日本比目鱼在种群增殖计划中被释放。一个以社区为基础的管理系统被用于这个比目鱼渔业，渔民支付他们每年上岸量的5%来经营种群增殖计划。此外，自1993年以来，渔民同意不捕捞全长< 30厘米的比目鱼，以最大限度地提高种群增殖投资的经济收益。我们的鱼市场调查显示，释放比目鱼每年贡献额外的30-90吨的渔获量。然而，自1996年以来，放养的经济效益有所下降，这主要是由于鱼价和回捕率下降。另一个问题是在实施种群增殖计划时从未考虑野生比目鱼的种群动态。一个占主导地位的一年级的野生比目鱼的发生会导致显着增加登陆，并删除需要释放孵化饲养的青少年。然而，该方案不能轻易终止，因为它在使渔民认识到渔业管理的重要性方面发挥着重要作用。如何使股票增值计划更加灵活有效，是一个困难而又重要的现实问题。
In Fukushima Prefecture, one million hatchery-reared juvenile Japanese flounder Paralichthys olivaceus have been released annually in the stock enhancement program since 1996. A community-based management system is used for this flounder fishery, where fishers pay 5% of their annual landings to operate the stock enhancement program. Also, since 1993, fishers have consented not to catch flounder < 30 cm total length to maximize economic gains from the investment in stock enhancement. Our fish market surveys revealed that released flounder annually contributed an additional 30–90 tons to the catch. However, the economic efficiency of stocking has reduced since 1996, which has been largely attributed to a decline in fish price and recapture rate. Another problem is that the population dynamics of wild flounder have never been considered during implementation of the stock enhancement program. The occurrence of a dominant year-class of wild flounder causes a dramatic increase in landings and removes the need to release hatchery-reared juveniles. However, the program cannot be easily terminated because it plays important roles in having fishers recognize the importance of fishery management. It is a difficult but important realistic problem concerning how to make the stock enhancement program more flexible and effective.
