What is the best PCR protocol for my agency to ID sharks and rays?<\/h3>\n

Led by Mote\u2019s Dr. Demian Chapman<\/a> (also an adjunct at Florida International University) and FIU biologist Dr. Diego Carde\u00f1osa, portable and cost-effective PCR testing is revolutionizing science-based enforcement and driving international collaboration in shark conservation. Use the decision tree below to determine what type of PCR is the best for your shark product (e.g., fins) identification needs and capacity. Please contact Dr. Demian Chapman (dchapman@mote.org<\/a>) for any questions or a consultation on how to establish PCR testing in your shark product inspections.<\/p>\n

Information on species-specific PCR to detect CITES-listed species<\/h3>\n
\"\"

Species specific PCR involves using a set of primers that are designed to amplify a particular species or set of species. PCR of this kind can be run on any conventional thermal cycler and visualized using agarose gel electrophoresis. It can also be run on any real time thermal cycler that will detect amplification itself. The cost of species-specific PCR is likely to be ~ $1USD per sample, but the drawback is if the sample does not originate from a species with a primer then it will not be identified.<\/p>\n

Species-specific PCR tests have been developed and validated for many CITES-listed sharks and rays that are common in the fin trade.<\/p>\n

Universal PCR test: DNA ID<\/h4>\n

The universal PCR test DNA ID uses a single set of primers and protocol to identify a shark sample to the species level no matter what species it comes from. Unlike species-specific PCR that provides a positive or negative finding for a selected subset of species, DNA ID provides a clear species determination. DNA ID offers a fast, cost-effective, and accurate method for identifying elasmobranch species\u2014sharks, rays, and skates\u2014using PCR. Designed to support conservation enforcement and combat illegal wildlife trade, this assay distinguishes species by analyzing the unique melting behavior of PCR products generated from DNA isolated from any type of tissue (e.g., fins, meat, skin). Validated across hundreds of vouchered specimens, the protocol can be run in the field and is optimized for high-throughput processing at a cost of $USD1.50 per sample. DNA ID currently identifies over 80 elasmobranch species commonly encountered in trade, with ongoing efforts to expand coverage.<\/p>\n
