Gambusia holbrooki are an alien pest fish invading the freshwater ecosystems. This species threatens more than 30 native species, causing biodiversity and economic loss. Lokman Norazmi proposes a genetic solution to this problem: Trojan Chromosome Carriers Strategy. Female fish with male genotype are released into the wild, thus producing a male-biased population leading to the collapse of the fish population.

Trojan Fish: Breaking the Wall of Alien Fish Invasion
Lokman Norazmi is an early career researcher at the Institute for Marine and Antarctic Studies, University of Tasmania (UTAS), Australia and holds an academic position at Universiti Malaysia Terengganu. He obtained his PhD in Fisheries Studies from UTAS in 2016. Working as part of an interdisciplinary research group on genetic control of pest fish he has established an army of Trojan chromosome soldiers (fish) to fight a war against alien mosquitofish invasion in Australia. The research forms a blueprint for controlling many other aquatic invasive pests at large spatial scales.
