Barriers to migration are a major threat to freshwater fish populations. A novel measurement of swimming speed performance and an analytical model were used to calculate the probability that endangered Macquarie perch, Macquaria australasica Cuvier, can swim through instream structures. Over the range of river discharges (2.7-166MLday-1) and temperatures (10-22°C) examined, M. australasica could successfully pass through a rock-ramp fishway and nearby natural riffles under most river...[Show more]
