“…Legislation does not differ much among regions, with the establishment of limpet no‐take areas, minimum legal catch sizes, and seasonal fishing closures. Unfortunately, these actions have been largely ineffective in protecting such resource (Diogo, Pereira, & Schmiing, ; López et al., ; Martins et al., ; Riera et al., ), mostly because of illegal harvesting and lack of or insufficient enforcement. Protective measures need to be adjusted to the particular life‐history traits of P. candei in each archipelago (e.g., temporal variation in reproduction, recruitment, population dynamics).…”

The uptake of natural living resources for human consumption has triggered serious changes in the balance of ecosystems. In the archipelagos of Macaronesia (NE Atlantic), limpets have been extensively exploited probably since islands were first colonized. This has led to profound consequences in the dynamics of rocky shore communities. The Patella candei complex includes various subspecies of limpets that are ascribed to a particular archipelago and has been the focus of several taxonomic surveys without much agreement. Under a conservational perspective, we apply morphometric and genetic analyses to test subspecies boundaries in P. candei and to evaluate its current population connectivity throughout Macaronesia (Azores, Madeira, and Canaries). A highly significant genetic break between archipelagos following isolation by distance was detected (F ST = 0.369, p < .001). Contrastingly, significant genetic differentiation among islands (i.e., Azores) was absent possibly indicating ongoing gene flow via larval exchange between populations. Significant shell‐shape differences among archipelagos were also detected using both distance‐based and geometric morphometric analyses. Adaptive processes associated with niche differentiation and strong barriers to gene flow among archipelagos may be the mechanisms underlying P. candei diversification in Macaronesia. Under the very probable assumption that populations of P. candei from each archipelago are geographically and/or ecologically isolated populations, the various subspecies within the P. candei complex may be best thought of as true species using the denomination: P. candei in Selvagens, Patella gomesii in Azores, Patella ordinaria in Madeira, and Patella crenata for Canaries. This would be in agreement with stock delimitation and units of conservation of P. candei sensu latu along Macaronesia.

“…Finally, our seventh model contained all 15 variables from the other six models and one new variable, regulation knowledge. Other compliance research (e.g., [ 5 , 25 ]) strongly supports this inclusion, as without correct regulation knowledge non-compliance may be widespread.…”

A New Approach to Identifying the Drivers of Regulation Compliance Using Multivariate Behavioural Models

2016

Non-compliance with fishing regulations can undermine management effectiveness. Previous bivariate approaches were unable to untangle the complex mix of factors that may influence fishers’ compliance decisions, including enforcement, moral norms, perceived legitimacy of regulations and the behaviour of others. We compared seven multivariate behavioural models of fisher compliance decisions using structural equation modeling. An online survey of over 300 recreational fishers tested the ability of each model to best predict their compliance with two fishing regulations (daily and size limits). The best fitting model for both regulations was composed solely of psycho-social factors, with social norms having the greatest influence on fishers’ compliance behaviour. Fishers’ attitude also directly affected compliance with size limit, but to a lesser extent. On the basis of these findings, we suggest behavioural interventions to target social norms instead of increasing enforcement for the focal regulations in the recreational blue cod fishery in the Marlborough Sounds, New Zealand. These interventions could include articles in local newspapers and fishing magazines highlighting the extent of regulation compliance as well as using respected local fishers to emphasize the benefits of compliance through public meetings or letters to the editor. Our methodological approach can be broadly applied by natural resource managers as an effective tool to identify drivers of compliance that can then guide the design of interventions to decrease illegal resource use.

“…Without data on compliance, managers have very little basis for planning enforcement actions, rating the success of compliance efforts, and the design of new interventions (Arias et al, 2015). Over the years, a number of data sources have been used to assess compliance or effectiveness of fishery closures, including: questionnaires and interviews (Bergseth et al, 2015), onboard observer data (Palka et al, 2008), biological surveys (Lewison et al, 2003;Tewfik and Béné, 2004;McClanahan et al, 2009;Diogo et al, 2016), surveys of derelict fishing nets and lines (Williamson et al, 2014), law enforcement records (Mann, 1995), vessel tracks from GPS beacons (Detsis et al, 2012;Öztürk, 2015;Petrossian, 2015), shore based camera images (Lancaster et al, 2017), aerial observations of fishing boats (Haggarty et al, 2016).…”
