A globally invasive fish, Eurasian tench (Tinca tinca) is spreading through the St. Lawrence River and poses an imminent invasion threat to the Great Lakes. Following its illegal release into a tributary of the St. Lawrence River in 1991, tench has spread throughout the river’s main stem over the past decade, and its abundance in commercial fishing bycatch in the river has grown exponentially. The tench is a generalist benthic consumer with largely undocumented ecological impacts in North America. Reports from other invaded regions indicate that it can compete with other benthic fishes, host a diverse assemblage of parasites and pathogens, degrade water clarity in shallow lakes, limit submerged macrophyte growth, reduce gastropod populations, and promote benthic algal growth through top-down effects. Risk assessments and climate-match models indicate that the Great Lakes are vulnerable to tench invasion, and they signal the need for timely comprehensive actions, including development and implementation of monitoring and rapid-response protocols, including prevention or slowing of natural dispersal through canals.

“…To obtain an effective reduction of the risk in the short term, current research indicates that proper bait disposal by anglers is crucial to avoid biological invasions of freshwater and estuarine ecosystems (Kilian et al., ). Because many anglers do not regard improper bait disposal as an undesirable behaviour, information campaigns about aquatic invasions should be a first step towards improving disposal behaviour (Seekamp et al., ; Sharp, Cleckner & DePillo, ; Shaw, Howell & Genskow, ), provided that increased awareness will be coupled with an increased availability of waste bins around water bodies and fishing ponds.…”

Anglers can be significant vectors for non‐native species (NNS) in freshwater ecosystems, and monitoring their behaviour can be a useful way to counteract biological invasions. However, anglers may be unwilling to reveal their real behaviour in conventional surveys. In this study, the Randomised Response Technique (RRT) and the Bean Method (BM) survey technique were compared using direct questions to obtain frequency estimates of four angler behaviours that may affect NNS management in freshwater ecosystems: angling without a license, release of macroinvertebrates in the environment, use of fish bait and unauthorised fish restocking. Higher estimates were obtained from responses to RRT than BM questions, and BM provided contradictory results. Use of the RRT is recommended in those human dimension studies that explore angler behaviour as a vector for aquatic invasions.

“…Based on our findings that stakeholders are poorly informed about the status of exotic mussels in SK and the province's vulnerability to a mussel invasion, managers should develop a long-term, multi-party AIS strategy focused on prevention (Leung et al 2002;Lovell et al 2006;Sharp et al 2016), early detection, and eradication (Vander Zanden et al 2010). Invasive mussels are now established in most regions surrounding SK, particularly at sites such as Lake Winnipeg, which are directly linked to the Qu'Appelle drainage by river flow.…”

In lakes but not in minds: stakeholder knowledge of invasive species in prairie lakes

Humans are key vectors in the spread and establishment of aquatic invasive species (AIS), and human behavior can exacerbate or help prevent further spread of non-native species. Therefore, stakeholders' knowledge is critical to preventing establishment of AIS. However, stakeholders' AIS knowledge in prairie lakes remains poorly understood. We used a survey questionnaire in Saskatchewan, Canada, to assess the state of AIS knowledge, identify predictors of knowledge, and optimize management strategies. Statistical analyses of the responses of 440 participants indicated a generally low level of AIS knowledge, suggesting low communication success. Respondents were generally more aware of non-native fishes than plants. Of concern was the observation of substantial knowledge gaps regarding non-native mussels and important preventative behaviors that may have devastating ecological, social, and economic consequences if left unaddressed. Better understanding of AIS issues was significantly associated with several trans-situational (age, sex and education), situational (recreational purpose and using multiple lakes), and lake-related knowledge (awareness of eutrophication) predictors. Exploitation of these predictors is recommended to improve effectiveness of outreach and communication efforts. Specifically, we propose that management strategies focus on improving communications by streamlining outreach messages, targeting low-knowledge groups (e.g., swimmers, cabin owners), and expanding education campaigns.
