HYDROBIOLOGICAL STUDIES ON THE GREAT BERG RIVER, WESTERN CAPE PROVINCE

Abstract
This is the first of a series of papers on the ecology of the Great Berg River in the Western Cape Province, South Africa. The topography and the flora are dealt with shortly and the physical and chemical conditions are described in some detail. The fauna is described broadly and related to the physical zonation of the river; the part played by the physical conditions in the zonation of the fauna is discussed and conditions are compared with those found in other parts of the world.
