Abstract: A fundamental challenge for both sustainable fisheries and biodiversity protection in the Neotropics is the accurate determination of species identity. The biodiversity of the coastal sharks of Guyana is poorly understood, but these species are subject to both artisanal fishing as well as harvesting by industrialized offshore fleets. To determine what species of sharks are frequently caught and consumed along the coastline of Guyana, we used DNA barcoding to identify market specimens. We sequenced the mitochon… Show more

“…However, the presence of so many species at risk of extinction in one of the most important fishing zones and elasmobranch conservation hotspots is a major concern both for conservation and the long-term sustainability of local fisheries. In Guyana’s coast, the western part of the elasmobranch conservation hotspot where BNC is classified 18 , thirteen shark species were identified using COI 36 , of which nine (~70%) are listed as either threatened, vulnerable or near threatened by IUCN. Only four species are not shared ( Isogomphodon oxyrhynchus , Mustelus canis , M .…”

“…In a different study carried out off Cubagua, also located in the northeastern region, Cordovés et al (2010) found that the most frequently captured ray species were H. guttatus (48.9%), Myliobatis freminvillei (18.0%), and H. americanus (15.7%). However, further to the east, between Trinidad and Tobago and Guyana, the most important species in commercial landings were R. lalandii and C. porosus (Shing 2006, Kolmann et al 2017. Altogether, these results show that sharks belonging to the genus Mustelus and rays belonging to the genus Hypanus are important elasmobranch groups in the northeastern region of Venezuela.…”

“…(18.0%) y H. americanus (15.7%). Por otra parte, más hacia la zona oriental, entre Trinidad y Tobago, y Guyana, las especies más importantes en las capturas comerciales fueron R. lalandii y C. porosus (Shing 2006, Kolmann et al 2017. Estos resultados, en su conjunto, muestran que los tiburones del género Mustelus y las rayas del género Hypanus constituyen grupos de elasmobranquios importantes en la región nororiental de Venezuela.…”

“…Although, there is a new, quick and cheaper version being used named ''Multiplex real-time PCR'' (<4 hours and $0.94 USD per sample), being capable to detect nine of the twelve sharks listed under CITES in a single reaction (Cardeñosa et al 2018), but still depends on a good workstation in field to support all the equipment's and a source of electricity to cover all these elements, prerequisites scarcely found in field of most regions of Brazil. Still, not all species are barcoded and available for comparison (Kolmann et al 2017). Some even cheaper alternatives are available such as the software's created to allow an accurate identification through the use of fins photos (e.g., iSharkFin).…”
