| Research Abstract |
In order to raise production yields and to facilitate material cycling in extractive aquaculture areas in Sanriku ria coast, feasibility to introduce aquaculture of the Japanese common seacucumber Stichopus japonica was examined. In spite of losses of in situ instruments and experimental corves of S. japonica due to tsunami attacks in February 2010 and March 2011, S. japonica has proven to be useful as a new aquaculture organism under oyster and scallop rafts due to 1) its significantly higher growth under the rafts than outside, and 2) significantly higher assimilation rates of carbon and nitrogen with feces of shellfish as foods than those with commercially available feeds.
