What kind of living organisms, where, and how many of them are present in the marine environment? This is a basic question, but the answer has yet to be discovered. Meanwhile, it is believed that humankind has captured many marine animals as food resources and has significantly reduced marine resources as a result. In this project, by using the latest DNA analysis technology and intensive field observations, we will create a bio-map of marine life groups existing in Northwest Pacific Ocean. Furthermore, we will develop an algorithm that can enable us to estimate the amount of marine resources by using the obtained information.

In order to properly conserve, maintain and utilize marine resources, it is essential to comprehensively understand their food chain structure. However, this has not been achieved yet due mainly to methodological limitations. The information obtained through this project will allow us to find ways to appropriately utilize and manage marine life groups and to determine the amount of food resources in the ocean for humankind to consume in a sustainable manner.
