“…The type of bait used to arm BRUVS depends on the availability of what local fishermen catch; therefore, it is generally composed of Indigenous species. Regarding the family Clupeidae, the most common species used is Sardinops sagax [21,23,25,28,32,35,36,46,47,56,63,64,66,68,72,74,81,83,93] for the Scombridae family is Scomber scombrus [33,53,67,79] followed by "tunas" Euthynnus affinis [53], Katsuwonus pelamis [43,71], Thunnus albacares [40], Euthynnus alletteratus [42]. Bait can be composed either of a single species or of mixtures of species and/or their parts: in [88] the bait housing contained a 100 g mixture of minced pilchards (80 g), falafel (10 g) and tuna oil; in [89] baits used to attract sharks included fish scraps, cephalopods, and/or cetacean flesh and oil; in [73] the bait was composed of 500 g of Sardinella brasiliensis and barracuda viscera, Sphyraena barracuda.…”

Cartilaginous fish face significant threats due to overfishing and slow reproductive rates, leading to rapid declines in their populations globally. Traditional capture-based surveys, while valuable for gathering ecological information, pose risks to the health and survival of these species. Baited Remote Underwater Video Systems (BRUVS) offer a non-invasive alternative, allowing for standardized surveys across various habitats with minimal disturbance to marine life. This study presents a comprehensive review of BRUVS applications in studying cartilaginous fish, examining 81 peer-reviewed papers spanning from 1990 to 2023. The analysis reveals a significant increase in BRUVS usage over the past three decades, particularly in Australia, South Africa, and Central America. The most common BRUVS configurations include benthic setups, mono-camera systems, and the use of fish from the Clupeidae and Scombridae families as bait. BRUVS have been instrumental in studying 195 chondrichthyan species, providing insights into up to thirteen different aspects of the life histories. Moreover, BRUVS facilitate the monitoring of endangered and data-deficient species, contributing crucial data for conservation efforts. Overall, this study underscores the value of BRUVS as a powerful tool for studying and conserving cartilaginous fish populations worldwide.

“…Marine protected areas (MPAs) can restore depleted fisheries and degraded habitats (Blampied et al, 2022; Fraschetti et al, 2013; Guidetti & Sala, 2007; Stevens et al, 2014), and are a key management tool to conserve marine biodiversity and other marine resources (Duarte et al, 2020; O'Leary et al, 2016). From 2000 to 2020, the number of designated MPAs in the Mediterranean Sea has increased from 109 to 1209, and their coverage has increased over 30‐fold (data from MedPAN & SPA/RAC, 2021).…”

Marine protected areas (MPAs) can protect and restore marine biodiversity and fisheries, but there are concerns that they may also benefit invasive species. The spatial and temporal colonization of invasive lionfish (Pterois miles) in the eastern Mediterranean was compared across zones with varying fishing restrictions (no fishing, recreational and commercial fishing, and commercial fishing only), and stations where targeted removal events were conducted by volunteer SCUBA divers. Lionfish density in no fishing areas was nearly double that of areas with commercial fishing only, and over four times greater than in areas where both commercial and recreational fishing were allowed. Lionfish density increased with depth, possibly due to easier human exploitation in shallow waters (0–10 m) that are accessible to recreational spearfishers. Targeted removals by volunteer divers decreased lionfish densities by over 60%, while areas without removals had a 200%–400% increase. Along with management actions, natural and ecological processes might drive lionfish densities within MPAs, and the speed with which lionfish colonized fishery‐restricted zones, emphasized the need for a more sophisticated MPA management strategy that considers invasive species impacts and dynamics in an ecosystem‐based approach.
