Evaluating the efficacy of the Florida Keys’ angler-assisted permit tagging program

Abstract

The use of angler-based tagging programs in recreational fisheries is on the rise, as they provide managers with effective, inexpensive means of collecting information. However, such programs are rarely evaluated for efficacy during the course of the program. Our study tagging program was the recreational permit Trachinotus falcatus (Linnaeus) fishery in the Florida Keys, which began in 2010. We evaluated the program for potential improvements using two complimentary approaches: an email-based survey of anglers and an advection–diffusion simulation model. Survey respondents reported potential fish stress and poor access to tags as the biggest obstacles to tagging permit. Respondents also cited poor data feedback from scientists as a potential area for improvement. According to the advection–diffusion simulation, the current level of tag returns is insufficient for accurately and precisely estimating movement parameters. The Florida permit tagging program could be greatly improved with greater communication between scientists and anglers. Data feedback and angler rewards could each increase angler buy-in. Tag retention could have a strong effect on the tag return rate and deserves more attention. Tag reporting could also have a strong impact on the tag return rate. The Florida permit tagging program needs more work to become a success, but has the potential to provide benefits for scientists and anglers.
