Bait dealers' roles in preventing the spread of aquatic invasive species and fish pathogens in the Great Lakes region

Abstract

Abstract The spread of fish pathogens and aquatic invasive species (AIS) is an ongoing challenge in the Great Lakes region. Bait dealers can prevent the spread of fish pathogens and AIS through their business practices and by educating their customers. Little is known, however, about whether and how they fulfill these roles. Licensed bait dealers in the Great Lakes region were surveyed by mail during fall 2013 to assess their awareness and concern about fish pathogens and AIS, actions they took to prevent their spread, and factors influencing these actions. Most bait dealers were aware of AIS and fish pathogens, many were concerned about them, and held beliefs suggesting their desire to take action to prevent their spread. These concerns and beliefs, however, did not always lead to action. We found two factors, not previously examined, that affected the probability of actual behavior. First, we found differences in participation in business practices by whether or not the state/province had regulations pertaining to those business practices. We also found differences by state/province in the degree and type of communication methods used to educate their customers. Second, we found greater economic dependence on bait sales was associated with increased AIS-preventative business actions and communication with customers. If fishery managers want to increase the number of bait dealers taking action to prevent the spread of AIS and fish pathogens, they may wish to promote additional regulations in states and provinces that do not currently have them, or strengthen regulations already in place.
