SOCIAL MEDIA DATA REVEALS ANGLER MOVEMENT NETWORKS AND RISK OF SPECIES INVASIONS
Human-mediated movement of aquatic invasive species via recreational fishing represents a significant and growing source of invader introductions into freshwaters. Angler activities that relocate invasive organisms include entanglement on fishing gear, boat hulls, and outboard engines, or use of non-native species as live bait. Understanding when and where anglers are fishing is pivotal for preventing the spread of detrimental invaders, but traditional approaches to inferring angler movement are often sparse in spatiotemporal resolution. Social media platforms now provide an emerging and powerful source of data to quantify geographic patterns of human activities. Anglers are highly active on social media (e.g., Flickr, Twitter and Instagram), and geotagging of fishing photographs represents a previously untapped source of angler spatial distribution data. Furthermore, fishing apps provide waterbody-specific locations of anglers and information on their bait and gear use. Here, we leverage these new data sources to quantify connections between waterbodies in terms of the magnitude, direction and timing of angler movements, with the goal of identifying potential invasion hubs. Our study will directly inform interagency management interventions for nuisance invasive species by visualizing angler movement networks and determining how they change through time.
