A BOBBER’S PERSPECTIVE ON ANGLER-DRIVEN VECTORS OF INVASIVE SPECIES TRANSMISSION
Prevention of aquatic invasive species transmission by recreational fishing and boating is a fundamental management challenge. These activities can entrain non-native plants and animals via tangled lines, bait buckets, or hull encrustation, leading to introductions into new waterbodies. With hundreds of millions of people participating in fishing trips each year, understanding angler movement behavior can provide critical insight into the most effective locations and scales at which to apply preventative measures. Angler behavior is often inferred from infrequently and sparsely conducted surveys that provide limited spatial and temporal insight into this challenge. Here we capitalize on a big data opportunity provided by ReelSonar’s recently launched iBobber, a sonar-enabled bobber with over 3,000,000 records of fishing location, water depth, and environmental variables collected over three years. By quantifying geographic patterns of fishing activities and assessing how these patterns change seasonally, we will explore angler behavior in terms of fishing frequency and distance traveled between sites, and characterize the attributes of fished ecosystems. Our study offers novel insight into spatiotemporal patterns of angler behavior and carries important implications for predicting and preventing future transmission of aquatic invasive species via recreational fishing.
