To predict the influence on fish stocks which were caused by environmental change in the fishing ground of shallow sea areas, we have developed the Shallow-Sea Ecological Model(SSEM) which that focuses on living organisms, especially fish and benthos. By applying the SSEM in the Seto-Inland Sea of Japan, we have simulated another aspect of influence on fish stocks that was caused by oxygen deficient water mass and nutrient loads. From the simulated result of the fish stocks, it was indicated that the stock of fish and benthos has shown a relative difference between the western sea and the eastern sea in the Seto-Inland Sea. According the to prediction, results of fish stocks that were caused by oxygen deficient water mass, it was estimated that the pelagicfish stock increases about 6 %, whereas the stocks of demersalfish and benthos decreases about 30% and 70%, respectively. On the other hand, it seemed that there was an increased in the fish stocks of demersalfish and benthos in the eastern sea of Seto-Inland Sea by nutrient loads reduction.

내만(inner bay)과 내해(inland sea)에 다량의 질소, 인이 유입하면 식물플랑크들의 증식(적조현상)과 빈산소 수괴 현상 등의 수질문제가 발생한다. 이 때문에 본 연구가 대상으로 하는 Kitan(기담) 해협을 포함하는 Seto(뇌호)내해(inland sea)에 있어서는 1973년 Seto내해 환경임시조치법이 제정된 이후 정부차원에서 수질오탁의 원인이 되는 COD, 인 등의 총량규제가 실시되어 왔다. (중략)

The tonguefish, Cynoglossus robustus and C. abbreviatus (Order Pleuronectiformes, Family Cynoglossidae), inhabits on soft and sand mud bottoms at depth of 20∼85 m around Korea, China and Japan(Nakabo, 1993; Okamura et al., 1970). The tonguefishes are economically important species and are relatively abundant among the fishes found in the Seto Inland Sea(Inaba, 1963: Inaba, 1988). (omitted)

Gymnodinium mikimotoi is one of several species of flagellates that cause harmful red tides. The red tides of G. mikimotoi have occurred only along $33-35^{\circ}$ N, e.g. Chinhae Bay in Korea, tile Seto Inland Sea and Kumane-Nada in Japan. I try to reproduce the formation of red ties of G. mikimotoi at Suo-Nada and Iyo-Nada, the western part of Seto Inland Sea, Japan in July 1985 with the use of four-dimensional assimilation model including the biological process of G. mikimotoi in this paper.

Feeding ecology was compared among the three tonguefishes Cynoglossus abbreviatus, C. joyneri and C. robustus, collected from Seto Inland Sea, Japan, from June 2000 to May 2001. They are benthivores, consuming mainly gammarid amphipods, shrimps, crabs, gastropods, bivalves and ophiuroids. C. abbreviatus consumed greater proportions of ophiuroids whereas C. joyneri and C. robustus ate more amphipods and shrimps. While C. abbreviatus consumed mostly ophiuroids in all size classes, the diets of C. joyneri and C. robustus showed ontogenetic changes in feeding habits; smaller individuals of C. joyneri and C. robustus consumed gammarid amphipods, whereas larger C. joyneri ate shrimps and gastropods, and larger C. robustus fed mainly on gastropods, crabs, bivalves and polychaetes. Cluster analysis based on diet similarities emphasized that the three Cynoglossus species could be categorized on a size-related basis into three feeding groups: smaller C. joyneri and C. rubustus (<25 cm TL) could be classified as group A, and the larger of them (>25 cm TL) as group B, whereas C. abbreviatus was categorized as group C. This means that some degree of resource partitioning can occur among the three Cynoglossus species. The seasonal changes in the diets were also significant for the three Cynoglossus species.

The management of water quality and fishery resources with a major environmental problem in eutrophic coastal sea is studied. The numerical experiments using the water-sediment quality model (WSQM) were carried out for the management of water quality at the Seto Inland Sea in Japan. The results of long-term water quality simulation showed responses of seawater quality to input loads to vary in different localities. A formula roughly forecasting water qualify to estimate the effect of loading abatement was proposed. The simulation for the improvement of seawater quality showed the abatements of nutrient loads such as total phosphorus (TP) and total nitrogen (TN) as well as organic loads such as chemical oxygen demand (COD) to be peformed in the eastern Seto Inland Sea from Bisan Seto to Osaka Bay. On the other hand, it is indicated that the increase of loading leads to the increase of primary production. while not straightly to the increase of fish production for the catch of fisheries.

Time series satellite image data were used to discuss the possibility of the industrialization of the Kunsan area. The satellite observation was performed from 1979 to 1987 and it revealed a big change in the geographical features due to the rapid development of this area. From the previous experience regarding the industrialization of the coastal district of the Seto Inland Sea, the Kunsan area is very promising as an industrialized world trade center.
