At present, the only management techniques available to control non-native fishes are physical removal (e.g., electroshocking), dewatering or ichthyocides. Unfortunately, all of these methods negatively impact native fauna as well as the targeted non-native fishes and require a great deal of effort (and therefore, funding). Herein, we propose development and testing of a genetic technique (Trojan Y) to control non-native fishes. Currently, the concept of using Trojan Y technology to control non-native species exists solely as a theoretical construct. Our project is the first to attempt application of this theory to the real world (in this case, the Greater Everglades). If we are successful in development of the technology, it could potentially be applied to a wide variety of species, including other fishes (e.g., brown hoplo), invasive applesnails, the Australian red claw crayfish and the green mussel.
