Risk assessment and screening for potentially invasive fishes
Kolar, C., 2004, Risk assessment and screening for potentially invasive fishes: New Zealand Journal of Marine and Freshwater Research, v. 38, p. 391-397.
Preventing the introduction of potentially invasive species is becoming more important as this worldwide problem continues to grow. The ability to predict the identity range of potential invaders could influence regulatory decisions and help to optimally allocate resources to deal with ongoing invasions. One screening tool presented here, using species life history and environmental tolerances to identify potential invaders similar to past invaders, can be used to predict the potential invading species. Another screening tool, genetic algorithms, can be used to predict the potential range of an invading species. Use and further development of tools such as these, that are quantitative and relatively transparent, would give managers and other decision makers more information for making better-informed decisions.
