I recently received an e-mail from Marty Mann of the FWC:
It is the desire of Florida Fish and Wildlife Conservation Commission (FWC) to work closely with bass anglers, clubs, and tournaments to ensure all users enjoy safe and quality fishing and boating while protecting the environment. Recently, FWC has been receiving many reports that anglers are installing fish attractors in lakes and we are trying to get the word out that this activity requires a permit from the Florida Department of Environmental Protection. Without a permit, it is considered littering and is illegal. The FWC is concerned that anglers are participating in an illegal activity and may not even be aware of it. We are also concerned that anglers are putting environmentally unfriendly materials in the lake to serve as attractors as well as placing attractors in water depths that may become navigational hazards.
