Inland recreational fisheries are ecosystem service hotspots, providing disproportionate subsistence, economic, and cultural benefits to many communities. However, freshwaters are transforming at a rapid rate and are sensitive to multiple drivers including climate change and land-use change. Managing transforming inland systems presents challenges as some drivers, such as climate change, are beyond local control. Other influential factors including fisheries harvest and species assemblage are potentially under local control, but it is unclear the impact these drivers have on inland recreational fisheries. I sought to understand the role of harvest and species interactions on inland recreational dynamics to inform climate adaptation approaches. To do this, in chapters 1 and 2 I evaluated the role of harvest in inland recreational fisheries using multiple approaches. In chapter 1, I scaled-up waterbody-specific harvest estimates to estimate the statewide magnitude of harvest and consumption to understand the contribution of inland recreational fisheries to food security and the economy. I found that inland recreational fisheries consumption was likely an important food source for angling communities and contributed $63 million annually, which went unmeasured. In chapter 2, I took an in-depth analysis into the harvest dynamics of a single, multi-use fishery, walleye (Sander vitreus), by applying a novel production approach. I found prolonged and increasing production overharvest in the northern Wisconsin walleye fishery, likely contributing to species declines in combination with a complex of other factors including climate change, emphasizing the need for sensitive assessment metrics. Then in chapters 3 and 4, I evaluated the impact of species interactions on inland recreational fisheries through an intensive whole-lake fish removal experiment in a north temperate lake. I removed ~285,000 warm water Centrarchidae spp. from a 33.1 ha lake and found a ~23% decline in centrarchid biomass. One cool water species, walleye, did not respond, however another cool water species, yellow perch (Perca flavescens), biomass increased by ~900%, emphasizing the contrasting responses thermally-similar fishes can have to changing food web interactions. These studies demonstrated that harvest and species assemblages are influential drivers of change for inland recreational fisheries.
