Article
The release of cold-water from hypolimnetic zones of impoundments sharply reduces downstream riverine water temperature. This cold-water pollution (CWP) can extend for hundreds of kilometres, severely challenging the physiological ability of aquatic fauna, particularly ectotherms such as fish, to maintain essential processes such as metabolism, dev...
Article
Spawning patterns in fish that use temperature as a spawning cue are responding to long‐term changes in the climate. The threatened Murray Cod, Maccullochella peelii (Mitchell), is an important apex species in inland south‐eastern Australia. Information from 1461 spawnings collected from hatcheries over 40 years was combined with environmental, met...

The volcanic crater lakes of southern western Victoria, Lakes Purrumbete and Lake Bullen Merri have long supported high quality and productive recreational salmonid fisheries. Both lakes are regularly stocked with hatchery-bred rainbow trout, brown trout and chinook salmon to sustain popular and productive put-grow-and-take recreational fisheries....
Article
Suitable habitat for many temperate freshwater species of salmonids is predicted to dramatically decline, yet many hatcheries still release millions of juvenile salmonids into rivers and lakes annually with little or no post release monitoring. This is, in part, because marking of hatchery reared fish is often not compulsory and currently available...
