Abstract

This report has two major components:

PART I Fish fauna of the Hotham River (including the impact of the Lion’s Weir on fish migration) Part I of the study was conducted prior to the construction of the Lion’s Weir Fishway and reports on the fish fauna of 22 sites in the Hotham and Williams River catchments and the impact of the Lion’s Weir on fish migrations. Salinisation of the catchment and species salinity tolerances were found to be the main determinant of fish distributions.

PART II Fish utilisation of the Lion’s Weir Fishway Part II provides data on fish utilisation of the Lion’s Weir Fishway between late July and November 2003.
