A preliminary assessment of fish passage through a Denil fishway on the Edward River, Australia

Research output: Book/ReportCommissioned report

Abstract

The obstruction of migration pathways is frequently implicated in the worldwide declines of freshwater fish. Fishways are commonly constructed to overcome these effects of weirs and fishway technology is advancing rapidly. Although many different concepts have been trailed in Australia, the Denil fishway is a relatively inexpensive design with substantial potential for widespread application. A Denil fishway can be simply described as an open channel containing a series of upstream-sloping ‘U’-shaped baffles without intervening pools. Denil fishways have been constructed worldwide and provide passage for many species, with varying degrees of success.
