In recent decades, many jurisdictions have established regulations governing the use of live baitfish in recreational fishing. These regulations are usually motivated by environmental concerns, such as the role that live baitfish play in the spread of invasive species and aquatic diseases. One question that might be posed by policymakers is whether limiting the use of live baitfish could impact the general public's interest in fishing. In this study, we conduct a before-after control-intervention (BACI) analysis to test whether live baitfish regulations in the United States are followed by changes in recreational fishing. Using data from the 1960s to the present day, we analyze four states that have implemented live baitfish restrictions: Maine, New York, Vermont and Colorado. We find that live baitfish restrictions do not cause a decline in the public's participation in fishing. Our results can empower policymakers to craft evidence-based regulations on the use of live baitfish while remaining confident that such policies are not likely to cause any unintended consequences on the recreational fishing community.
