Molecular genetic studies of the yabby, Cherax destructor Clark

A study of genetic variation in the yabby (Cherax destructor) was undertaken using a number of different molecular techniques. The results have significantly improved our understanding of the genetic structure, evolution and taxonomy of this important freshwater species. The findings also contribute to the sustainable exploitation of yabbies for aquaculture.

Dynamics of endogenous food production in Cherax destructor Clark culture ponds

This study examined endogenous food production in crayfish culture ponds and the pond dynamics resulting from the interactions of pond bottom and water column parameters under a crop flooding strategy.

Nature's line : George Goyder over South Australia

A biographical work presenting 19th century South Australian surveyor general and founder of Darwin, George Goyder, as a significant figure in colonial environmental history. Focuses on tracing the growth of experience and insight which enabled him to map, as Goyder's line, his insight into the importance of rainfall variability.

Genetic studies on Cherax destructor Clark in relation to aquaculture

Investigated three strains of the common freshwater crayfish (yabby), to determine the potential for genetic improvement of this species for aquaculture. Crossbreeding generated viable progeny and differences were found between strains in reproductive performance, sex ratios, morphology and overall genetic divergence measured by DNA sequencing.
