The capture, transportation and culture of [[bait fish]] can spread damaging organisms between [[ecosystem]]s, endangering them. In 2007 several American states enacted regulations designed to slow the spread of fish diseases, including [[viral hemorrhagic septicemia]], by bait fish.<ref>{{Cite web |title=DNR Fishing Regulation Changes Reflect Disease Management Concerns with VHS |url=http://www.michigan.gov/dnr/0%2C1607%2C7-153-10371_10402-170245--%2C00.html |url-status=dead |archiveurl=https://web.archive.org/web/20081214010208/http://www.michigan.gov/dnr/0%2C1607%2C7-153-10371_10402-170245--%2C00.html |archivedate=December 14, 2008 |website=www.michigan.gov}}</ref> Because of the risk of transmitting ''[[Myxobolus cerebralis]]'' (whirling disease), [[trout]] and [[salmon]] should not be used as bait.

Anglers may increase the possibility of contamination by emptying bait buckets into fishing venues and collecting or using bait improperly. The transportation of fish from one location to another can break the law and cause the [[introduced species|introduction of fish]] alien to the ecosystem.
