Interdisciplinary study on effective utilization of local fisheries resources with aim of resional promotion

在日本南部的鹿儿岛湾，盘足虾Plesionika semilaevis（十足目，Caridea）是小型底围网渔业的主要副渔获物。由于半滑舌鳎的市场价格较低，半滑舌鳎经常被丢弃在海里。为了有效地利用这一资源，本文从渔业生物学、海洋食品科学和海洋社会科学等多个学科的研究方法出发，对鹿儿岛湾半滑舌鳎的资源现状和存在的问题进行了研究。在本次调查中，以个体数量和个体重量计，半滑舌鳎为最优势种。此外，全年98%的个体发生在中央湾的最深处。在鹿儿岛湾，半滑舌鳎的产卵场和孵化场估计覆盖了其整个分布区。在鹿儿岛湾还对弯吻粗鲑的繁殖生物学进行了研究。结果显示，产卵期为5 ~ 11月，6 ~ 7月为产卵高峰期。海洋食品科学（新藤）：开发了软化半滑舌鳎外骨骼的方法。海洋社会科学（佐久间）：从品牌化的角度考虑了半滑舌鳎等当地渔业资源的有效利用。一个单独的公司可以被认为是风险企业的等价物。此外，在渔业合作社没有建立一个单独的空白的权力，它是作为一个地区的跨行业合作的地方空白。

In Kagoshima Bay, southern Japan, the pandalid shrimp Plesionika semilaevis (Decapoda, Caridea) is a principle by-catch of small-scale bottom seine fishery. Because the market price of P. semilaevis is low, P. semilaevis is often discarded in the sea. In order to utilize P. semilaevis effectively as a local resource, the present status and problems of this resource were examined by the research methods from the fields of fisheries biology, marine food science and marine social science.Fisheries biology (Ohtomi): The distribution and population structure of P. semilaevis was first studied in Kagoshima Bay. P. semilaevis was the most dominant species by numbers and weight of individuals collected in the current survey. Further, 98% of the individuals of occurred at the deepest part of the central bay, all year round. In Kagoshima Bay, the spawning and hatching grounds of P. semilaevis were estimated to cover the entire areas of its distribution. The reproductive biology of southern rough shrimp Trachysalambria curvirostris was also studied in Kagoshima Bay. As the results, the spawning season was estimated to last from May to November, with a peak during June and July.Marine food science (Shindo): The methodology for softening the external skeleton of P. semilaevis was developed.Marine social science (Sakuma): In this part, effective utilization of local fisheries resources such as P. semilaevis was considered from the viewpoint of branding. An individual bland could be considered as thing equivalent to venture business. Also at Fisheries Cooperatives without the power of building an individual bland, it was built as a local bland by cross-industrial cooperation of an area.
