The popular ICZM (Integrated Coastal Zone Management) shows us the potential approach toward a coastal area with harmonious interaction between human-being and natural environment. Seto Inland Sea which has undergone serious environmental degradation and anthropogenic changes. In order to recover and sustain its unparalleled values, rebuilding a sound environmental policy system from top to bottom is highly required. The ecosystem services and their monetary values are also estimated buy CVM necessary for sustainability assessment, due to their powerful roles in representing human-coastal zone relationship and supporting sustainability of a “Satoumi” system. The sustainability assessment framework for Seto Inland Sea, which consists of Inclusive Wealth, “Satoumi”, and ecosystem service approach was developed. Key words: Satoumi, ICZM, Seto Inland Sea, Ecosystem service, CVM, Sustainability Ⅰ.INTRODUCTION Japanese term “Satoumi” refers to coastal zone that has sound bio-productivity and biodiversity through human activities, which is composed of five elements. Three factors support the conservation and revitalization of coastal zone, i.e., material circulation, ecosystem and communication. Another two facilitate the realization of “Satoumi”, i.e., field of activity and executors of activity. -

Genetic Relationships Among Lancelet Populations in Seto Inland Sea Inferred from Mitochondrial DNA Sequences
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Hiroshima University Institutional Repository 広島大学総合博物館研究報告 Bulletin of the Hiroshima University Museum 5: 1︲6, December 25, 2013 論文 Article Genetic Relationships among Lancelet Populations in Seto Inland Sea Inferred from Mitochondrial DNA Sequences Koichiro KAWAI1, Hiroyuki KATO, Hidetoshi SAITO and Hiromichi IMABAYASHI Abstract: Genetic relationships were examined among a total of 74 lancelets, Branchiostoma japonicum (Willey 1897), collected at 16 stations in the Seto Inland Sea on the basis of the sequence of the COI region of mitochondrial DNA. Genetic divergence was usually high at the stations near straits. Besides, there were no significant relationships between geographical and genetic distances of individual lancelets. As many as 62 haplotypes were recognized, among which only three comprised multiple individuals from distant stations, and the remaining ones comprised a single individual. In a dendrogram, some clusters were made up of individuals from nearby stations whereas other ones were made up of those from more or less distant stations. These results suggest that the high genetic heterogeneity of the lancelet population in the Seto Inland Sea is maintained by continuous genetic exchanges via a large-scale dispersion at long planktonic stages driven by tidal and constant currents in this region.

Rivers in the Japanese archipelago, separated from the continent of Asia by about 17 Ma, have experienced an intermittent exchange of freshwater fish taxa through a narrow land bridge generated by lowered sea level. As the Korean Peninsula and Japanese archipelago were not covered by an ice sheet during glacial periods, phylogeographical analyses in this region can trace the history of biota that were, for a long time, beyond the last glacial maximum. In this study, we analyzed the phylogeography of four freshwater fish taxa, Hemibarbus longirostris, dark chub Nipponocypris temminckii, Tanakia ssp. and Carassius ssp., whose distributions include both the Korean Peninsula and Western Japan. We found for each taxon that a small component of diverse Korean clades of freshwater fishes Citation: Taniguchi, S.; Bertl, J.; migrated in waves into the Japanese archipelago to form the current phylogeographic structure of Futschik, A.; Kishino, H.; Okazaki, T. -

H. M. Enamul Kabir, Masahiko Sekine, Tsuyoshi Imai, Koichi Yamamoto Division of Environmental Engineering, Graduate School of Sciences and Technology for Innovation, Yamaguchi University, Ube, Japan ABSTRACT Marine microplastics pollution has been an emerging global threat. This study investigated mi- croplastics pollution in the ‘Seto Inland Sea (SIS)’ and ‘Sea of Japan (SJ)’ surrounded Yamaguchi prefecture areas in Japan. The density separation method was applied to extract microplastics from sea surface sediment and water samples. Polymeric compounds were identified through ATR-FTIR analysis. The average microplastic abundances were 112.57 ± 121.30 items/kg in sediment and 57.46 ± 20.82 items/L in water. Abundance comparisons revealed similar level of pollution in both sea areas and medium to high-level pollution than others around the world. Characterization revealed that fragments and small microplastics (< 1,000 µm) predominated sediments. Fragments and films were major shapes in the SIS sediments while only fragments predominated the SJ sediments. Large microplastics (1,000–5,000 µm) fibers predominated water in all the areas. Transparent microplastics predominated both the sediments and water. Polyethylene, polyvinyl alcohol, and polypropylene were major polymers in sediments while polyethylene terephthalate and polyethylene predominated water. No significant correlations of microplastics abundances and characteristics were observed between sediment and water. Anthropogenic activities and environmental factors were speculated to be the main sources of microplastics in these areas. -

The spa~ing season ex tends trom April to June. About 100-300 matured males and females are introduced in a' large tank of 100-1,000 m3 aapacity. The floating eggs are gathered and transferred into a net cage. The optimum incubation temperature ranges from 15;Oto 17~5°C, and the optimum specifia gra vity is higher than 1.023. The ne~ly hatched larvae are introduced into floating tanks hanged in a large conarete tank and aultured for about 10 days. The prelarvae are released into large aonarete tanks and cultured for about 20 days. O,yster eggs, rotifers (~achionus~liaatilis), eopepods eollected by net, and nauplius of Artemia salina are used for feeding i ividuals in prelarval stage. The survival rates of prelarvae are improved in tanks ~ith abunàant propaga tion of uni-cellular green algae. postlarvae are transferred into net cages installed at sea and reared to jry stage for about 10-40 days. Survival rate of trY from hatching to 20 mm total length is about 3 J. RESUME. La daurade royale atteint Za maturit4 sexueZle ~ l'âge de 3 ans. Sa saison de ponte s'4tend d'avril d juin. -
