SCUBA diving application and the analysis of diver's observation or sampling data were reexamined at the artificial breakwater of the fossil fuel power plant station in Fukushima Prefecture.
In the shallow coastal region at about 10m depth, the distribution of sessile organisms except the algae could be recognized, if an experienced biologists surveyed from the surface to the bottom by way of a single belt-transect.
As for the quantitative sampling area, 900-2500cm2 is recommended from the species-area relations.
And the similarity of such shallow-water fauna has clearly shown no zonational pattern.
It is important when assessing the faunal distribution not only to use the numerical index but also to use pictorial representation, therefore the computer program CDM-KITE was introduced as a new tool.
