Fishing Activity

We project how human population change (2018 to 2046) and aquatic invasive species (AIS) establishment events of bigheaded carps (Hypopthalmichthys spp.) and grass carp (Ctenopharyngodon idella) might combine to affect future Canadian recreational fishing activity for the Laurentian Great Lakes. Human population change is expected to affect the total number of fishing trips (increase of about 143 000 trips or 11.4%) more than any of the AIS establishment events (maximum decrease of about 44 000 trips or 3.5%). The projected 11.4% increase to the number of fishing trips from human population change, however, lags the 38% projected increase to Ontario, Canada’s population from 2018 to 2046. Increasing urbanization and an aging population, which are associated with reduced rates of fishing participation, were responsible for this difference. The combined effects of human population change and AIS establishment illustrate the importance of accounting for human population change as it reverses the conclusions and results in a projected net increase of between 92 000 and 125 000 in the number of fishing trips. The combined model also identifies potential growth areas for fishing such as shore fishing by urbanites on the western portion of Lake Ontario.

Entry Points

The Great Lakes are one of the most invaded aquatic ecosystems in the world, and the spread of fish pathogens and aquatic invasive species (AIS) has become a serious issue for fishery management in the Great Lakes. Our study applies the Drivers-Pressures-State-Impacts-Responses model (DPSIR) to identify social-ecological linkages in the spread of pathogens and AIS by anglers, boaters, and bait dealers in the Great Lakes. We developed a conceptual DPSIR model based on input by staff members in governmental agencies and non-governmental organizations that have been involved in the management of pathogens and AIS. The integration of managers' input to develop the model is a novel approach for understanding fisheries. Most previous studies using the DPSIR framework did not account for natural resource managers' input even though the DPSIR framework is frequently applied to provide information to these groups. The identified relationships in our model provide multiple entry points for empirical, interdisciplinary research. These studies would help understand the effectiveness of management responses to change human behaviors, and to understand and predict changes in the Great Lakes ecosystem and fishery. The model could also be used to promote understanding of the impacts of pathogens and AIS on the fishery, and to increase awareness of human behaviors that contribute to the continued spread. Future studies could further expand or replicate the model with input by other stakeholder groups such as bait dealers and/or anglers and boaters to identify if these groups share an understanding of the management problem and responses.

Central Regions

The St. Lawrence Seaway links central regions of North America to the Atlantic Ocean via the Great Lakes navigation system. Harmful non-indigenous aquatic invasive species have increasingly been introduced into the Great Lakes largely through the ballast water of inbound ships involved in international commerce. A variety of solutions have been proposed, with some advocating closure of the St. Lawrence Seaway to international shipping. Historically, it was an important artery linking grain surplus regions in Canada and the United States with international markets. However, during the past two decades the Seaway's role has diminished as a grain transport artery. The objective of this paper is to develop an increased understanding of this decline and to offer thoughts regarding the likely reversal of the forces that may have caused it. Analysis indicates declining imports by selected world regions and domestic transportation legislation is central to the decline.

Secondary Spread

Biological invasions continue to accelerate, and there is a need for closer integration between invasive species research and on-the-ground management. In many regions, aquatic invasive species have established isolated populations, but have not yet spread to many sites that provide suitable habitat. In the Laurentian Great Lakes region, several Great Lakes invaders such as zebra mussel ( Dreissena polymorpha ), rainbow smelt ( Osmerus mordax ), and spiny water flea ( Bythotrephes longimanus ) are currently undergoing secondary spread to the smaller inland lakes and streams. This paper describes recent advances in forecasting the secondary spread of aquatic invasive species and presents a framework for assessing vulnerability of inland waters based on explicit assessment of three distinct aspects of biological invasions: colonization, site suitability, and adverse impact. In many cases, only a fraction of lakes on the landscape are vulnerable to specific invasive species, highlighting the potential application of this type of research for improving invasive species management. Effective application to on-the-ground resource management will require that research aimed at assessing site vulnerability be translated into management tools.
