Environmental DNA (eDNA) survey of Tilapia infestations in the Moranbah/Isaac region

Objectives: Conduct a survey of tilapia infestations in the Moaranbah/ISAAC region using environmental DNA(eDNA)as the detection method. Outcomes: Based on the eDNA survey results, tilapia are present in the Moranbah and ISAAC region due to the presence of tilapia DNA. The eDNA survey detected tilapia DNA in seven sites from the Grosvenor creek and ISAAC sites. The detection rates for tilapia were variable between sites, however strong detections were observed for Grosvenor 1 and 2 as well as ISAAC 1 study sites. The strong detections found from these sites may suggest high abundance of tilapia in the local areas.
