Michael Hutchison completed a PhD on freshwater fish of the Murray
River, Fisheries biologist Dr Michael Hutchinson will present two studies at this years conference. First up is the captive breeding of jungle perch. When this is achieved, the project aims to reintroduce jungle perch in their traditional habitats in south-east Queensland and restore this popular angling fish to its former glory. |

The Murray-Darling Basin Commission has recently funded DPI&F to conduct a research project on improving the post-stocking survival of hatchery-reared threatened fish. Research on fish stocking has shown that in general the majority of stocked fish are taken by predators on the day of release. Fish that survive the first day have a higher chance of making adult size. Many fish that are stocked have never been exposed to predatory fish or have had only limited exposure to predatory birds. Fish stocked at larger sizes (eg 30 cm), in addition to failing to recognise predators may also have become used to a diet of pellets. These fish are usually inefficient at foraging for live foods.
