- Species identification is a fundamental part of recognizing and describing biodiversity. The difficulty in assigning an organism to a biologically meaningful category should be well considered before the use of any molecular identification tool. Molecular methods or tools provide valuable data on species diversity through their ability to detect variation at the DNA level. These methods are based on the assumption that individuals from a same species carry specific DNA (or protein) sequences that are different from those found in individuals from other species. Traditionally fish species identification is based on external morphological and meristic features. But in most cases morphological and meristic features are of limited value for identification and differentiation purposes, even with whole specimens, because they can show either considerable intraspecific variations or small differences between species. DNA-based identification methods offer an analytically powerful addition or even an alternative. Here we briefly review modern technological achievements for DNA analysis that offer great potentials for the identification of fish species.
