Population Genetics of Australian Barramundi (Lates calcarifer)

This site is the location for sharing of population genetic data (genotypes) of Australian Barramundi generated at James Cook University within the Centre for Sustainable Tropical Fisheries and Aquaculture and the School of Marine and Tropical Biology.

Project Background:

Barramundi (Lates calcarifer) is an iconic fish species supporting commercial, aquaculture and recreational fisheries throughout tropical Australia. Due to the importance of barramundi to tropical communities there is a need to understand how this species will respond to climate change and how its distribution, genetic structure, population carrying capacities and local recruitment may be impacted. For aquaculture, potential threats and opportunities due to climate change also need to be identified.


The population genetics research being undertaken on barramundi and referred to here is part of a broader project at James Cook University that aims to understand how climate change will impact both wild and cultured barramundi stocks and importantly to identify adaptation options various user-sectors can consider to minimise future impacts. This will be acheived through the characterisation of genetic, physiological, bioenergetic and immunological adaptations that may be present between populations (stocks) and integration of this data with climate models.

The research is funded by the Australian Department of Climate Change and Energy Efficiency (DCCE) and the Fisheries Research Development Corporation (FRDC).


Summary of population genetics data held:

We currently have 1245 genotypes consisting of 16 polymorphic microsatellite loci from barramundi sampled between 1988 and 2012 with sampling spread across 45 different locations from Broome in Western Australian to the Mary River in SE Queensland.

Access to the genotypes is presently restricted to authorised collaborators but will be made publically available at the completion of the project and after acceptance of the final report and associated journal articles.
