Resources for Teaching and Learning about Exotic Species

Exotic species are organisms transported by humans, wildlife, wind, and water into regions where they did not historically exist. On the other hand, native organisms of North America are generally considered species that were ecologically established prior to the time of European settlement (Pultz, 1995). Considerable data from various scientific and commercial sources have provided convincing evidence that all U.S. shores are impacted by exotic aquatic invaders. For instance, the zebra mussel and green crab have had serious ecological and socioeconomic impacts from the Great Lakes to the Gulf of Mexico, and from the Atlantic to the Pacific oceans-and in rivers and lakes in between. According to the Aquatic Nuisance Species (ANS) Task Force (2000), Great Lakes water users spend tens of millions of dollars on zebra mussel control every year. As a result of such consequences, the National Sea Grant College Program and other organizations are very concerned with the increasing number of aquatic exotic species. The full economic and ecological impacts of each exotic species are continually under investigation. EXOTIC AQUATICS CONTROL AND EDUCATIONMost exotic species are both accidentally and intentionally spread by the human beings. For instance, some species can be picked up and transported on boating equipment, including trailers, motors, tackle, downriggers, anchors, axles, rollers, and centerboards. Others can be carried in the water of livewells, baitbuckets, motors, bilges, and transom wells (IISGCP, 1998). Since zebra mussels were first discovered in Lake St. Clair in June 1988, they have spread to all five of the Great Lakes and their connecting waterways, as well as inland lakes and rivers across North America, primarily through water recreation pathways.

Even though there are artificial methods to control exotic aquatics, including chemical, biological, mechanical and physical controls, educational efforts can be the most important key to solving current and future problems. If teachers and students, along with members of their communities, become more knowledgeable about exotic species, it is then possible for individuals and groups to make informed decisions about their behavior related to the introduction and spread of exotic invaders (EATM, 2000).

As Haury and Milbourne (1999) described, the Internet can provide "a way to break out of the school walls and engage students with people and resources scattered around the world." With the Internet resources described here, teachers can encourage increased student attention to aquatic invaders. Furthermore, these key information sources can be used by science communicators, parents, students, researchers, and other professionals who are making decisions about their own lifestyles. INTERNET RESOURCESExotic Aquatics on the Move

This site is based on a joint project of six Sea Grants and six Geographic Alliances. Geographic information (origin & distribution), educational resources, and picture collections will be very helpful in teaching and learning about exotic aquatics.
