Global shark currency: the distribution, frequency, and economic value of shark ecotourism (2011, background): “For example, shark populations on the US east coast have declined an estimated 80–90% since the mid1980s, as a result of target and non-target fisheries (Baum & Blanchard, 2010; Baum et al., 2003; Clarke, Magnussen, Abercrombie, McAllister, & Shivji, 2006; Myers et al., 2007).”
Fishing down the deep (2006, background): “More recently, fisheries exploitation has spread from coastal areas to the open ocean and a general decline in fish biomass has been reported (Baum et al. 2003; Christensen et al. 2003; Myers and Worm 2003): as a consequence, many marine species are of serious conservation concern (Casey and Myers…”
Assessing the size, growth rate and structure of a seasonal population of whale sharks (Rhincodon typus Smith 1828) using conventional tagging and photo identification (2007, positive): “The decline of shark populations worldwide (FAO, 1994; Camhi et al., 1997) and speciﬁcally in the Atlantic and Gulf of Mexico (Baum et al., 2003; Baum and Myers, 2004) has prompted calls for stronger conservation measures for some species such as ﬁshing bans, quotas and listing in international…”
Socio-economic value and community benefits from shark-diving tourism in Palau: A sustainable use of reef shark populations (2012, positive): “For this reason, fishing for sharks both as a target species and as by-catch has severely reduced shark populations in many parts of the world’s oceans (Baum et al., 2003; Field et al., 2009; Myers, 2003; Myers et al., 2007), including tropical reef systems (Robbins et al.”
Large-scale experiment shows that nylon leaders reduce shark bycatch and benefit pelagic longline fishers (2008, background): “Global declines in shark popuations may not be as severe as suggested by Baum et al. (2003) f the switch to nylon by many longline vessels during the 1980s esulted in large declines in shark catchability and if the mortality ates of escaped sharks are relatively low.”
Business partner or simple catch? The economic value of the sicklefin lemon shark in French Polynesia (2011, positive): “There is a general consensus that the ongoing decimation of shark populations by commercial fishing is putting many species in danger of extinction (Baum et al. 2003; Clarke et al. 2006; Ferretti et al. 2008).”
Reducing sea turtle interactions in the Hawaii-based longline swordfish fishery (2007, background): “This is of interest due to concerns over the status of some shark populations, the sustainability of their exploitation and ecosystem-level effects from shark population declines (FAO, 1999; Bonfil, 2002; Baum and Myers, 2004; Baum et al., 2003; Burgess et al., 2005a,b; Fowler et al., 2005; Ward a”
Global-scale genetic identification of hammerhead sharks: Application to assessment of the international fin trade and law enforcement (2005, background): “…exploitation and well-documented susceptibility of shark populations to collapse in response to overfishing has made conservation and management of sharks an issue of urgent and international concern (Bonfil 1994; Weber and Fordham 1997; FAO 2000; Musick et al. 2000; NMFS 2001; Baum et al. 2003).”
Size and structure of a photographically identified population of manta rays Manta alfredi in southern Mozambique (2011, background): “These aggregation sites offer some of the best opportunities to gather data on species whose population sizes or distributions are otherwise unclear or unknown, a fact that ultimately hampers the assessment and management of their populations and fisheries (Bonfil 2002; Baum et al. 2003 ).”
A review of shark satellite tagging studies (2011, background): “An increasing number of studies worldwide have demonstrated rapid declines of large sharks over the last decades due to over-fishing practices (Baum et al., 2003; Myers and Worm, 2005; Dulvy et al., 2008; Ferretti et al., 2008, 2010).”
Overview of the conservation status of cartilaginous fishes (Chondrichthyans) in the Mediterranean Sea (2007, background): “…data on catch trends for this species in the region, although significant reductions in thresher sharks have been reported through catch per unit effort (CPUE) comparisons in the Northwest Atlantic pelagic longline fishery (Baum et al. 2003), and suspected declines have occurred elsewhere.”
Predicting ecological consequences of marine top predator declines. (2008, background): “Declines in marine top predators Predators that occupy high trophic levels in marine habitats, including marine mammals, large teleosts and sharks, have been declining worldwide at a rapid pace [1– 4]. Recent estimates suggest that populations of large sharks have declined regionally by 90% or more ”
