Steiner, H. A. (1991). Investigations at the fish ladder from the River Drau into the Kellerberg Loop. Osterreichs Fischerei. 44:87-100.
The measurings showed, that the installation of a fish ladder for the preservation of the flowing water continuum for the old branch of the River Drau is absolutely feasible, taking the ecological conditions and the fishery biological outline conditions into consideration. Beside variable outlets on account of the natural catchment area, the fish ladder at the Kellerberg Loop took the performance of the fish, disposition of the fish path and sufficient decoy current into consideration. The fish ladder was well accepted and serves as permanent living space for at least 10 different species of fish. The fish ladder also serves a good purpose with regard to ascents during the spawning time.
