Quantifying Pathways of Nonindigenous Aquatic Species

In 1999, President Clinton signed an executive order calling for establishment of a National Management Plan for Invasive Species. This plan, published in 2  1, calls for quantification of the various pathways by which nonindigenous nuisance species (NIS) enter or are distributed within the US. While the importance of ballast water as a pathway of NIS introductions into aquatic systems is well established, the importance of other pathways has not been quantified. Some of these pathways--live bait, pet, water garden, and biological supply trades--are widely thought to be increasingly important. This project will examine the relative importance of these different pathways through 1) quantification of organisms for sale by these industries in the southern Lake Michigan region; 2) identification of those species that are most likely to establish in the Great Lakes and connecting waterways; and 3) collaboration with local and national industry leaders in production of educational materials for them and their customers, and voluntary codes of industry conduct that will reduce the future risk of spreading NIS via these pathways. Collaboration with these industries will reduce the introduction and spread of NIS in the short term, and lay the groundwork for more effective and efficient future regulations, should they be necessary. Major Goals and Objectives: 1) To determine the importance of the trades in live bait, pets, water gardens, and biological supplies as pathways for the introduction of nonindigenous freshwater species. 2) To estimate the ecological and economic risks associated with given species in trade. 3) To reduce the numbers of high risk species in trade and to reduce the likelihood of release of organisms by customers.
