“…Consistent with the findings of Aguilar et al (2014), our surveys found the artisanal, pelagic longline fishery in Cojímar operates primarily within 20 km from shore and targets large species, including Swordfish Xiphias gladius, Sailfish Istiophorus platypterus, White Marlin Kajikia albida, Blue Marlin Makaira nigricans, and Dolphinfish (also known as mahi-mahi) Coryphaena hippurus. Sharks and scombrids are opportunistically caught and retained.…”

“…The NPOA-Sharks outlined, for the first time, actions and tasks to identify research needs and regulatory requirements for shark fisheries management and conservation in Cuba. As a result of Cuba's interest in generating information on sharks and its fisheries, progress has been made in understanding shark species diversity (Aguilar et al 2014) and connectivity and migratory patterns for some pelagic species, including those of conservation concern (Hueter et al 2017(Hueter et al , 2018. Productivity-susceptibility analyses also have been conducted to identify the vulnerability of various species to fishing pressure in Cuba (Puga et al 2018).…”

The Straits of Florida comprise an important migratory route for apex predators moving among the Gulf of Mexico, Atlantic Ocean, and Caribbean Sea. Off Cuba's northwestern coast, various gear types are used by Cuban fishers, including small-scale pelagic longlines. We report here the results of a 2011-2019 monitoring program for the longline fleet based in Cojímar, Cuba. This fleet comprises 134 small vessels targeting mostly swordfish (family Xiphiidae), billfishes (family Istiophoridae), tunas (family Scombridae), and sharks (class Chondrichthyes) within 20 km of Cuba's coast. Most operations are nocturnal with 11-12-h sets comprising an average of 56 hooks on 6,643 m of mainline. Five orders, eight families, and 18 species of sharks were documented in this fishery. Two carcharhinids (Silky Shark Carcharhinus falciformis and Oceanic Whitetip Shark C. longimanus) and two lamnids (Longfin Mako Isurus paucus and Shortfin Mako I. oxyrinchus) were the most abundant shark species caught, with shark CPUE averaging 1.98 sharks/trip (SD = 0.938). Catch abundance showed seasonal differences, with Silky Sharks and Longfin Makos more common in winter and Oceanic Whitetip Sharks more common in summer and autumn. Bimodal size structure in some species suggests multiple life stages utilizing the area, while the predominance of young sharks in species including the Oceanic Whitetip Shark suggests the importance of the area as juvenile habitat, possibly as a

“…Fishing currently poses the greatest threat to reef‐shark species globally (Dulvy et al , ), but most exploitation has occurred in the absence of fisheries data, and as such the effects of fishing on reef‐shark populations remain poorly understood. Overall, there have been reports of fishing pressure, both targeted and as by‐catch, for reef sharks in each family except Scyliorhinidae and Hemiscyllidae (Heupel et al , ; Tavares, ; Meneses et al , ; Aguilar et al , ; Table SI, Supporting Information). Amongst species, the threat posed by fishing differs depending on life‐history characteristics (Hutchings et al , ) as well as by habitat preferences and associated exposure to fishing pressure.…”

Reef sharks: recent advances in ecological understanding to inform conservation

Sharks are increasingly being recognized as important members of coral-reef communities, but their overall conservation status remains uncertain. Nine of the 29 reef-shark species are designated as data deficient in the IUCN Red List, and three-fourths of reef sharks had unknown population trends at the time of their assessment. Fortunately, reef-shark research is on the rise. This new body of research demonstrates reef sharks' high site restriction, fidelity and residency on coral reefs, their broad trophic roles connecting reef communities and their high population genetic structure, all information that should be useful for their management and conservation. Importantly, recent studies on the abundance and population trends of the three classic carcharhinid reef sharks (grey reef shark Carcharhinus amblyrhynchos, blacktip reef shark Carcharhinus melanopterus and whitetip reef shark Triaenodon obesus) may contribute to reassessments identifying them as more vulnerable than currently realized. Because over half of the research effort has focused on only these three reef sharks and the nurse shark Ginglymostoma cirratum in only a few locales, there remain large taxonomic and geographic gaps in reef-shark knowledge. As such, a large portion of reef-shark biodiversity remains uncharacterized despite needs for targeted research identified in their red list assessments. A research agenda for the future should integrate abundance, life history, trophic ecology, genetics, habitat use and movement studies, and expand the breadth of such research to understudied species and localities, in order to better understand the conservation requirements of these species and to motivate effective conservation solutions.

“…In a report on the swordfish fishery along the east coast of Florida, Berkeley and Campos (1988) noted that more shark species than target species were captured and that the overall mortality rate was 66% for 13 species of hooked sharks. Furthermore, in a recent 1-year survey (conducted from October 2010 through November 2011) of the pelagic longline fishery along the northwestern coast of Cuba, the longfin mako was the second-most abundant shark species landed (by number), exceeded only by the shortfin mako, out of the 15 different shark species observed (Aguilar et al, 2014). A nearly 5-year (from October 2010 through April 2015) pilot monitoring program of the same fishery documented the longfin mako as the most abundant pelagic shark species landed (MINAL, 2015).…”

“…), and other shark species (Reardon et al, 2006;Mucientes et al, 2013;Frédou et al, 2015). In a study of shark bycatch in the small-scale, pelagic longline fishery of northwest Cuba, Guitart Manday (1975) reported that the longfin mako was the sixth most common shark by weight of the 11 shark species reported; a more recent study of this fishery ranked the longfin mako higher in landings (Aguilar et al, 2014). Fins of longfin makos are of desirable quality and have been reported in the Hong Kong (Clarke et al, 2006), Chilean (Sebastian et al, 2008), and Indonesian fin trades (Sembiring et al, 2015).…”
