... Telemetry data varied in abundance, spatiotemporal resolution, and availability, with 47 telemetry studies contributing to our assessment of species mobility relative to MPA boundaries (Table B1), and of these, only four studies were conducted within the Palmyra-Kingman MPA. Furthermore, regardless of the number of telemetry studies available for any species, sufficient sample sizes are required to make conclusions about species ranges (Sequeira et al., 2019b) and tagging biases towards particular sexes, life history stages, or limited tag deployment durations may also influence results (Filous et al., 2022;Hays et al., 2020b). However, uneven data availability should not influence our conclusions regarding movement ranges for two reasons. ...

... Specifically, data were collected from 13 fixed-station acoustic receiver arrays from the study area shared via the Integrated Tracking of Aquatic Animals in the Gulf of Mexico (iTAG) regional tracking network (Friess et al. 2021). All detection data were derived from an ongoing tarpon acoustic telemetry tracking project (see Griffin et al. 2018Griffin et al. , 2022. Due to data limitations, only detection data from mature individuals (≥ 128.5 cm fork length, Crabtree et al. 1997) were used since movement patterns differ between life stages (Kurth et al. 2019). ...

... com). A rāhui aiming at biodiversity conservation purpose has been implemented recently in Tautira district, Tahiti (Bambridge et al., 2019), whereas a rāhui is currently serving educational purpose in Anaa Atoll, Tuamotu Archipelago (Filous et al., 2021), and the revival of ancient rāhui practices are currently being integrated in a spatial planning project in Mangareva, Gambier Archipelago, for stock replenishment of pearl oyster, at the request of farmers (André et al., 2022). ...

... Nonetheless, the uncontrolled expansion of this sector of the fishery has the potential to rapidly increase fishing mortality and cut off the supply of migrating fish that would otherwise be captured in the handline sector of the fishery. Therefore, a potential management solution is to cap the number of traps at its current level, in which trap operators with a history of involvement in the fishery are grandfathered into their concessions and additional permits are not issued until an existing permit is relinquished (Jennings et al., 2009 (Bijoux et al., 2013;Filous et al., 2020;Hamilton et al., 2012b;Hughes et al., 2020). Nevertheless, Rangiora's longnose emperor fishery is one of the largest domestic fisheries for coral reef species in French Polynesia (DRM, 2019) and given that assuming a mean rate of natural mortality its SPR is currently estimated to be just above the minimum threshold of overexploitation, small management actions taken now could make significant improvements to the sustainability of this fishery and guarantee that the resources continue to provide for the people of Rangiroa Atoll and the greater community of French Polynesia. ...

... The behavior of Yellowfin Tuna around FADs has been investigated extensively using ultrasonic telemetry, either with manual tracking or automated receivers (Holland et al. 1990;Cayré 1991;Marsac and Cayré 1998;Brill et al. 1999;Klimley and Holloway 1999;Dagorn et al. 2000Dagorn et al. , 2007Klimley et al. 2003;Ohta and Kakuma 2005;Edwards and Sulak 2006;Robert et al. 2012;Govinden et al. 2013;Stehfest et al. 2013;Filous et al. 2020). Yellowfin Tuna display a wide spectrum of relationships to FADs and other geological feature (e.g., seamounts) depending on fish size, location, and quantity of FADs present, ranging from short-term fidelity to long-term residency to no relationship (Klimley and Holloway 1999;Klimley et al. 2003;Ohta and Kakuma 2005;Edwards and Sulak 2006;Dagorn et al. 2007;Robert et al. 2012;Filous et al. 2020). ...

... To this end, an important starting point in the process of empowering communities to manage their fisheries is providing an assessment of their fisheries and an evaluation of management actions that could be implemented to improve their status (Crosman et al., 2020;Johnson et al., 2020a). Length-based stock assessments have proven effective in informing communities on the status of their resources, promoting management and measuring the biologic response of fish populations to management interventions (Filous et al., 2019b(Filous et al., , 2021Prince et al., 2015). These methods are costeffective and easy to implement, but require a basic understanding of the life-history parameters of targeted species and an adequate representation of the size distribution of the fish harvested in a given fishery (Hordyk et al., 2015a(Hordyk et al., , 2016. ...

... The establishment of positions, such as fishing guides, would enhance surveillance on the water and limit illegal fishing. If spawning-associated harvests of bonefish continue in Cuba, reductions in size (age) at maturity and maximum sizes may continue (Rennert et al. 2019), with population-level and financial implications (Johannes and Yeeting 2001;Filous et al. 2019Filous et al. , 2021. ...

... km 2 ) calculated in this study was orders of magnitude greater than the monthly core range (0.0001−0.016 km 2 ) and activity space (0.004−0.062 km 2 ) of giant trevally monitored at a coral reef in Australia (Lédée et al. 2015). This difference, however, may simply reflect the different time scales (annual vs. monthly) and the different spatial extent of the respective receiver arrays, given that the core home ranges (0.1−2.6 km) of actively tracked fish at an atoll in the South Pacific were more similar to this study (Filous et al. 2019). While the overall core home range size appears to exhibit variability amongst sites, giant trevally in various studies did appear to exhibit a persistent core area of habitat use representing a key habitat and a degree of site attachment. ...

... There are many examples of lights impacting migratory species during non-migratory phases of their life cycle, including sea turtles [30], mule deer [31], salmon [32], and moths [33]. For example, seabirds (including Procellariiformes), the majority of which are migratory, display positive phototaxis to land-based light pollution which has been shown to cause mass mortality [34]. ...

... EEZs around small islands provide potential for both sustainable local food and economic export to international markets. Fisheries resources in these areas include coastal and reef fishes such as parrotfishes, trevallies, snappers, groupers, and triggerfishes among others (Filous et al., 2019), as well as large pelagic migrants, especially tunas and billfishes (Christ et al., 2020). Overfishing of local species is of serious concern and several important species are considered to be at risk (Cinner & McClanahan, 2006;Sumaila et al., 2013). ...
