Using expert knowledge to estimate the potential of the Rideau and Trent-Severn Waterways for invasive and endangered species

It is important but challenging to study species lacking field data, such as potential future invaders or native species that are rarely found. In this study, we use expert elicitation to estimate the potential effect of anthropogenic structures (e.g., shipping locks, dams & weirs, and hydropower plant) and habitats in human modified aquatic ecosystems on the invasion of Asian carps and the restoration of endangered American eels. The preliminary results vary among experts and structures and provide opportunities for discussion and group learning among experts and managers. This webinar was presented by Dr. Hsien-Yung Lin, Carlton University.

On the Doorstep of the Great Lakes, Tench what is it, how did it get here, and what now

Tench, a Eurasian fish from the same family as Asian carps, was captured in the Bay of Quinte (Lake Ontario) in 2018. Over the past few decades, Tench has managed to stay out of the spotlight, despite expanding its range westward from the site of its illegal introduction in Quebec towards the Great Lakes. However, its recent rapid spread and increasing appearances in bycatch of commercial fisheries has raised alarm. In this webinar, we will delve into the history of the introduction of this fish, learn how to identify it, and describe what is known about the potential threats it poses to the Great Lakes and St. Lawrence River. We will also discuss what can be done to prevent the spread of Tench and reduce its impacts. This webinar was presented by Sunci Avlijas, McGill University

Grass Carp in Lake Erie: History, Status, and Habitat

Although Grass Carp have been captured in the Great Lakes since the early 1980’s, it was assumed that most were sterile escapees from stocked ponds, or incapable of successfully reproducing in available tributaries. However, spawning was first documented in the Great Lakes in 2015 with the collection of fertilized eggs from the Sandusky River, a Lake Erie tributary. Monitoring has since continued and spawning has been documented in multiple years in two Lake Erie tributaries, with some evidence suggesting that recruitment may have already occurred. Grass Carp consume aquatic vegetation and therefore may pose a threat to Great Lakes aquatic vegetation communities. This webinar covers the history and status of Grass Carp reproduction in Lake Erie and current research and management efforts. This webinar is presented by Dr. Patrick M. Kočovský, USGS and Nicole R. King, University of Toledo.

Socio Economic Risk Assessment of the Presence of Grass Carp in the Great Lakes Basin

“Socio-Economic Risk Assessment of the Presence of Grass Carp in the Great Lakes Basin” provides a detailed socio-economic analysis of the potential economic impact to Canada and the US of the establishment of Grass Carp in the Great Lakes. The study supplements the bi-national Ecological Risk Assessment of Grass Carp for the Great Lakes Basin (ERA) released in 2017. The Great Lakes are the world’s largest freshwater system, with 20% of the world’s fresh surface water and 95% of North America’s fresh surface water. The Great Lakes directly support the lives of approximately 40 million people in both the US and Canada. The Great Lakes are an important source of drinking water and support fish, wildlife, plants, thousands of wetlands and a variety of landscapes. They are home to commercial and recreational fisheries, numerous recreational activities, commercial transportation, and provide both tangible and intangible benefits to residents of Canada and the US.

Overview of Canadian Research on Asian Carp Prevention

The four invasive Asian carp species (Bighead, Silver, Black and Grass carp) represent an imminent threat to the Great Lakes ecosystem. These invaders would drastically alter native fish populations and habitats, which will also harm the commercial and recreational fishing industries. Due to this impending threat, scientific research is required to inform preventative strategies. This webinar will provide an overview of research in Canada directly related to the prevention of an Asian carp invasion. Examples of current research efforts include the development of models to determine which Canadian tributaries would be suitable to Asian carp spawning, and an evaluation of whether non-physical barriers would be effective in deterring the movement of Asian carps throughout high-risk tributaries. Additionally, risk assessments are being developed to inventory all potential paths of introduction, and their relative threat level. Canadian research forms a vital component of larger collaborative efforts to prevent the establishment of Asian carps in the Great Lakes. Presented by Paul Bzonek and Tej Heer from University of Toronto.

The Importance of Binational Collaboration in the Great Lakes Region to Address Asian Carps

Presented by Becky Cudmore from Fisheries and Oceans Canada and Dr. Marc Gaden from the Great Lakes Fishery Commission. The binational Great Lakes ecosystem is currently under threat from four high risk Asian carp species, Grass, Bighead, Silver and Black carps. The prevention of establishment of these invasive fishes is an identified priority for both the Canadian and American governments. Collaboration between the two federal governments is key in addressing these species. This webinar will provide background on Great Lakes governance and authorities around fishery management. Information specific to Asian carp governance will also be given and how groups like the Asian Carp Regional Coordinating Committee function to provide guidance. Examples of binational actions underway will highlight some of our successes and will include topics such as risk assessment, response, prevention, and enforcement. The webinar will end with a discussion on the importance of binational collaboration and where there are challenges.
