PhD Project: Population genetics of common carp (Cyprinus carpio) fry in different recruitment areas in the Darling-Basin (MDB), Australia.
This research is the most comprehensive study of common carp in a single river basin to date. The quantity of samples (983 in the MDB) and collection sites (36 in the MDB) exceeds any previous study of common carp, and is not often achieved amongst other studies of freshwater fish. This is the first study in which the population history of common carp has been investigated in detail at a local level, and in which management units for this species have been proposed.
A number of surprising findings have been made, namely the presence of the Prospect strain in the MDB, the extent of population genetic structuring in the Basin, the disparate distribution of the different stains as a result of human-mediated dispersal, and the cryptic introgression between goldfish and carp. It was shown here that despite being recently introduced, carp can exhibit population structuring within a single river basin,and that this structuring that is consistent with the population not yet being in mutation-drift-migration equilibrium and gene flow playing a larger role than genetic drift in shaping genetic structure. This study serves as a guide to other research groups looking to understand the population genetics of invasive freshwater fish species as a step towards their control.
