Despite the establishment of shark sanctuaries (e.g. The Bahamas), most nations have minimal shark fishery management outside of well-established marine reserves (e.g. Belize). I hypothesized that the diversity and abundance of exploited elasmobranchs (Caribbean reef shark Carcharhinus perezi, blacknose shark Carcharhinus acronotus, Atlantic sharpnose shark Rhizoprionodon terraenovae, Caribbean sharpnose shark Rhizoprionodon porosus, tiger shark Galeocerdo cuvier, great hammerhead shark Sphyrna mokarran, lemon shark Negaprion brevirostris) would be primarily driven by direct fishing pressure while the abundance of non-exploited elasmobranchs (nurse shark Ginglymostoma cirratum, southern stingray Hypanus americanus, Atlantic chupare stingray Styracura schmardae, yellow round ray Urobatis jamaicensis, whitespotted eagle ray Aetobatus narinari) is driven by alternative physical and/or anthropogenic factors (e.g. depth, reef type, local human population density) on Caribbean coral reefs. Baited remote underwater video (BRUV) surveys (N=981) were conducted at seven locations in Belize (active shark fishery) and ten locations in The Bahamas (shark sanctuary) from 2010 to 2016 to determine the relative abundance of reef-associated elasmobranchs. The diversity and abundance of exploited elasmobranchs were greater in The Bahamas than in Belize. Positive reserve effects on exploited apex predators (Caribbean reef shark, large migratory sharks) were possibly due to a combination of direct fishing and prey availability, while negative reserve effects on exploited mesopredators (small migratory sharks) were possibly due to direct predation or predator avoidance behavior. Non-exploited nurse sharks were common throughout Belize and The Bahamas but demonstrated positive reserve effects within Belize, possibly due to increased prey availability, and/or bycatch mortality or the legacy of their previous exploitation in fished areas of Belize. Non-exploited batoids demonstrated a greater abundance within Belize and within fished areas of Belize, possibly due to direct predation and/or predator avoidance in response to increased apex predator abundance in The Bahamas and marine reserves of Belize. Shark fishing results in direct and indirect effects on reef-associated elasmobranch abundance and diversity, which demonstrates the need for increased management of active shark fisheries in order to sustain non-consumptive exploitation (e.g. ecotourism) of these species."},{"label":"dcterms.available","value":"2018-03-22T22:39:01Z"},{"label":"dcterms.contributor","value":"Frisk, Michael G."},{"label":"dcterms.creator","value":"Clementi, Gina Marie"},{"label":"dcterms.dateAccepted","value":"2018-03-22T22:39:01Z"},{"label":"dcterms.dateSubmitted","value":"2018-03-22T22:39:01Z"},{"label":"dcterms.description","value":"Department of Marine and Atmospheric Science."},{"label":"dcterms.extent","value":"136 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/78119"},{"label":"dcterms.issued","value":"2017-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2018-03-22T22:39:01Z (GMT).
