DNA-Based Testing for Fish Species Substitution Media stories covering Therion's Fish Species Substitution work are available here. Are you confident that the fish you are buying, selling or perhaps eating at your favorite restaurant is the species that you think it is? Species Substitution is one of the more common forms of fraud in the seafood industry. Because (1) the meat of many species of fish share the same taste or texture and (2) it is difficult to perform visual species identification on fillets, it therefore becomes easy to substitute an inexpensive species for a pricey one. Therion offers a variety of DNA-based assays to differentiate among various fish species. Using the techniques of DNA sequencing or DNA amplification we have been able to address questions concerning substitutions for red snapper, grouper, tilapia and walleye. In addition, the scientists of Therion can develop novel assays to work with any other species of interest. Red Snapper or ??? Grouper or???
