The benthic habitat consists from abiotic (physiotope) and biotic (ecotope) components. The physiotope is characterized by seabed and associated waters properties. They influence on diversity of the flora and fauna. This process is directly dependent on the physical and chemical characteristics of the physiotope and its spatial structure. In conclusion the analysis of the benthic habitat along selected transects becomes more reasonable than limitation of the information to the static units (statistical rectangles). The paper describes 12 selected acoustic transects of the southern Baltic. For each transect nine parameters representing values of acoustic and environmental parameters were calculated and analyzed on the base of data collected in the autumns in the period 1995-2003 aboard the R.V. Baltica. Four parameters were characterizing seabed, next three hydrologic properties of water in the demersal zone, and last two – fish distribution. The parameters were estimated with the resolution of one nautical mile. Detail analysis of statistical and spatial distributions of all parameters was applied to classify and to compare the transects.
