dc.description SUPPORTING INFORMATION : TABLE S1: The D-efficient design for choice experiment 1 and the panhandle version that includes the block number, number of responses per block, task number, trip choices, and level of attributes that included size (slot vs. minimum) and bag limit, season length, and distance from shore. This choice experiment and version surveyed respondents from Florida, USA, that launched from the panhandle to fish for red snapper 2019–2020 (n = 172). TABLE S2. The D-efficient design for choice experiment 1 and the peninsula version that includes the block number, number of responses per block, task number, trip choices, and level of attributes that included size (slot vs. minimum) and bag limit, season length, and distance from shore. This choice experiment and version surveyed respondents from Florida, USA that launched from the peninsula to fish for red snapper 2019–2020 (n = 209). TABLE S3. The D-efficient design for choice experiment 2 and the panhandle version that includes the block number, number of responses per block, task number, trip choices, and level of attributes that included management option (current management vs. harvest tag), catch size and rate, and distance from shore. This choice experiment and version surveyed respondents from Florida, USA that launched from the panhandle to fish for red snapper 2019–2020 (n = 167). TABLE S4. The D-efficient design for choice experiment 2 and the peninsula version that includes the block number, number of responses per block, task number, trip choices, and level of attributes that included management option (current management vs. harvest tag), catch size and rate, and distance from shore. This choice experiment and version surveyed respondents from Florida, USA that launched from the peninsula to fish for red snapper 2019–2020 (n = 218). TABLE S5. Demographic characteristics of respondents to a survey that asked about their experience as a red snapper angler in Florida, USA, 2019–2020 (n = 766). TABLE S6. Results (mean ± SD) of questions that asked about the respondents’ experience as a red snapper angler in Florida, USA 2019–2020 (n = 766). These questions asked about how much the respondents fished and what changes they have seen in the size and number of fish in the Gulf of Mexico. TABLE S7. Respondents’ level of support (strongly oppose–strongly support) for alternative management options of various size limits (16″ minimum vs. 14–24″ harvest slot), bag limits (1, 2, and 4 red snapper/person/trip), season lengths (15, 25, and 40 days), and harvest tag system (10 red snapper per year with no size or bag limit and no season length) (n = 766). TABLE S8. Respondents’ level of support (strongly oppose– strongly support) for alternative management options of various size limits (16″ minimum vs. 14–24″ harvest slot), bag limits (1, 2, and 4 red snapper/person/trip), season lengths (15, 25, and 40 days), and harvest tag system (10 red snapper per year with no size or bag limit and no season length) (n = 766). The factor loadings for the composite variable “harvest tag support” are listed. TABLE S9. Composite variables that were used in the two choice experiments (SPCE1 and SCPE2) that were treated as covariates in the random parameter logistic models. These covariates were created by interacting the attribute level (management option, size and bag limit, season length, and on-water distance attributes) chosen with respondents’ support for or opposition to these attribute levels. TABLE S10. Parameter estimates, standard errors, and 95% confidence intervals for multinomial logistic regression that estimated effort of management option (current management vs. harvest tag) on effort response (decrease, stay the same, and increase). Coefficients are interpreted as odds ratios relative to a reference level of the effort response “stay the same”. en_US

dc.description.abstract The Gulf of Mexico red snapper fishery has been caught in a spiral of more restrictive regulations and disputed management. Current management measures have failed to reduce fishing mortality, owing in part to derby style fishing. A harvest tag system could potentially better limit fishing mortality without decreasing harvest seasons. In 2019/20 we surveyed 766 recreational anglers who fish in Florida with private boats to ascertain their preferences for regulation changes, and how they would alter their fishing effort if a harvest tag was implemented. Respondents were heterogeneous in terms of their preferences for harvest tags versus current management approaches, with most respondents preferring to maintain their current effort under the existing management approach of bag, size, and season limits. Respondents who preferred harvest tags indicated that they might increase or decrease fishing effort. Our findings suggest that more stringent regulations using current management approaches will not secure angler satisfaction or reduce fishing pressure on the red snapper stock. Harvest tags, though not preferred by all respondents, may allow regulators to better manage the number of anglers in the fishery and to rebuild the stock, although implementing this program will pose some challenges. en_US
