“…High radiance levels correspond to higher light intensities, indicating that greater fishing fleets and fish abundance were at sea [40]. Indeed, it was previously reported that many fisheries worldwide use artificial light to attract pelagic fish and increase fish catches, e.g., [41,47]. Our results suggested that there might have been a considerable number of fishing fleets operating near the fishing grounds of area B due to the relative abundance of fish during February and March 2017 (Figure 12a).…”

“…Waluda et al [40] used satellite-derived nighttime lights to show that fish catch was positively correlated with estimated fishing extent. Indeed, light intensity at night affects fish activity levels and aggregation [41,42]. Because monthly fish catch data at the study sites are not available, we used nighttime light intensity to approximate the temporal changes in fishery activity levels.…”

Two large fish assemblages were recorded in the overwintering fishing grounds of the East China Sea in February and March 2017. In this study, available time series of satellite-derived sea surface temperature, wind, chlorophyll a, and reanalysis data were used to explore the relationships between the observed large fish aggregations and environmental factors. The bottom waters of the fishing grounds were abnormally warm in winter 2017, and then experienced significant cooling due to the eastward movement of the Yellow Sea Cold Current, which was driven by the increased northwesterly wind from January to mid-March 2017. Fishing areas in the affected region, including No. 1891, which was abnormally warm, and No. 1592, which had a strong thermal front and high chlorophyll a concentration, might have provided suitable environments for the warm-temperature fish, resulting in the observed large fish assemblages. The abnormal temperature changes between winter and early spring 2017 may have been associated with changes in local ocean circulation.

“…Bowfishing at night on lakes and reservoirs, as opposed to rivers, is consistent with the safer and more relaxing conditions more commonly encountered, especially during the calm conditions that are most favorable for successful bowfishing. Night fishing with all gears and on all waters also presents special challenges for managers in monitoring and enforcement (Cooke et al 2017), sometimes resulting in fishery closures at night to reduce illegal take and improve stock assessments. Under the current near absence of regulation of bowfisheries, however, night fishing may be primarily chosen when targeting species that are more available to being taken at night, rather than to circumvent regulations.…”

In response to lacking information on bowfishing, bowfishers, and management planning nationwide, a survey was sent to 15,000 licensed Oklahoma anglers (bowfishers and non‐bowfishers) in 2021. Respondents (n = 1,346) were mainly male (73%) and white (74%), had an annual/5‐year license (46%) or a lifetime license (39%), and had an average age of 48 (1,182 respondents provided demographics). Questions to bowfishers gauged the importance of bowfishing compared to other fishing activities; trip frequency and motivation; where, when, and which species were targeted; the utilization of fish taken; and attitudes regarding bowfishing regulations. An estimated 24% of licensed anglers had bowfished before. Bowfishing participation in the previous year had more than doubled (4% in 2018 to 9.1% in 2020). Most (57%) had bowfished for 3 years or less; 49% identified as beginners, 43% identified as intermediate, and 8% identified as advanced. Overall, most bowfishing occurred by day (54%), in early summer (May–July), from shore (49%), and in rivers and streams (67%) or reservoirs (53%). Bowfishers sought carps (85%), gars (74%), and buffalofishes (32%). Bowfishers typically used shot fish for fertilizer or buried them (48%), used them for animal consumption (35%) or human consumption (32%), or returned them to the water (20%). Compared to non‐bowfishers, bowfishers reported a wider diversity of acceptable outcomes for fish species taken with any fishing method, particularly the nongame fishes. Most bowfishers (86%) and non‐bowfishers (94%) trusted the state management agency to appropriately manage native, nongame fishes. Bowfishers were mixed on their support for or opposition to having bowfishing regulations for these species. Some respondents noted that regulations would result in them bowfishing less (23%) or quitting bowfishing completely (6%). Thirty‐two percent of non‐bowfishers expressed interest in bowfishing in the future. The results of this survey will be used in Oklahoma and elsewhere to aid in designing sustainable bowfisheries that serve the broader public interest while conserving native, nongame species.

“…The effects of ALAN on fish attraction/aggregation are not lost on recreational fishers; recreational fishers often target artificially lit areas for night fishing, as they know certain target game species will follow baitfish into the illuminated areas (Cooke et al 2017).…”

Terrestrial, marine, and freshwater realms are inherently linked through ecological, biogeochemical and/or physical processes. An understanding of these connections is critical to optimise management strategies and ensure the ongoing resilience of ecosystems. Artificial light at night (ALAN) is a global stressor that can profoundly affect a wide range of organisms and habitats and impact multiple realms. Despite this, current management practices for light pollution rarely consider connectivity between realms. Here we discuss the ways in which ALAN can have cross-realm impacts and provide case studies for each example discussed. We identified three main ways in which ALAN can affect two or more realms: 1) impacts on species that have life cycles and/or stages on two or more realms, such as diadromous fish that cross realms during ontogenetic migrations and many terrestrial insects that have juvenile phases of the lifecycle in aquatic realms; 2) impacts on species interactions that occur across realm boundaries, and 3) impacts on transition zones or ecosystems such as mangroves and estuaries. We then propose a framework for cross-realm management of light pollution and discuss current challenges and potential solutions to increase the uptake of a cross-realm approach for ALAN management. We argue that the strengthening and formalisation of professional networks that involve academics, lighting practitioners, environmental managers and regulators that work in multiple realms is essential to provide an integrated approach to light pollution. Networks that have a strong multi-realm and multi-disciplinary focus are important as they enable a holistic understanding of issues related to ALAN.
