“…Many studies support the effectiveness of this mt-DNA fragment in the labeling and identification of fish species (Hebert et al 2004a, b;Hubert et al 2008b;Steinke et al 2009;Ardura et al 2010;Aquilino et al 2011;Asgharian et al 2011;Lakra et al 2011;Zhang and Hanner 2011) and processed fish products (Ardura et al 2010;Wong et al 2011). In some instances, however, closely related species may have diverged too recently to be unambiguously separated by COI barcode sequences (Toffoli et al 2008;Steinke et al 2009;Serra-Pereira et al 2010;Smith et al 2011).…”

Pseudoplatystoma species are highly prized South American Pimelodid migratory catfishes. Until recently, their taxonomy was not clearly established, with discrepancies between morphological and molecular analyses. Here, Pseudoplatystoma species from the Peruvian Amazon were characterized at the molecular level from a sample representing the observed range of their color pattern variations in the study area. Analyses were performed using seven microsatellite loci for 103 specimens and, for part of them (52), using sequences of two regions of their mitochondrial genome [Cytochrome Oxidase subunit I (COI) and Control Region (CR)]. Factorial correspondence analysis and assignment tests based on microsatellite polymorphism showed that the specimens originally identified as P. punctifer belonged to two different gene pools highly differentiated from P. tigrinum. Morphological examination identified two different morphotypes (with and without black stripes), suggesting the existence of two distinct taxa within P. punctifer. This result was corroborated by the ML tree based on CR sequences, where all individuals but four clustered in a similar way as in the FCA and Bayesian assignment tests. For these four individuals, mitochondrial introgression or retention of ancestral polymorphism was likely. In contrast, the ML tree based on COI sequences showed that reciprocal monophyly was not yet achieved for this marker for the two P. punctifer taxa. The existence of three sympatric species of Pseudoplatystoma in the Peruvian Amazon is discussed in relation to their molecular characteristics, color patterns and ecology. Evolutionary scenarios regarding their divergence are hypothesized.

“…Accidental substitution may occur due to morphological similarity among species, which hinders accurate identification (Ardura, Pola, Ginuino, Gomes, & Garcia-Vazquez, 2010;Buck, 2010;Cawthorn, Steinman, & Witthuhn, 2012). There are cases in which different species receive the same vernacular name, generating ambiguities that hinder the correct identification of species (Ardura et al, 2010;Buck, 2010).…”

“…There are cases in which different species receive the same vernacular name, generating ambiguities that hinder the correct identification of species (Ardura et al, 2010;Buck, 2010). Additionally, there are species that have different trade names in different regions of the same country or in different countries, which may cause accidental substitutions (Barbuto et al, 2010;Chakraborty, Aranishi, & Iwatsuki, 2007).…”

“…Substitutions lead to mislabeling and result in several problems associated with both economic losses (Ardura et al, 2010;Cline, 2012;Galimberti et al, 2013) and preservation issues because they mask the exploitation rate of endangered and overexploited species, thus affecting fishing control and management (Garcia-Vazquez et al, 2009;Lleonart, Taconet, & Lamboeuf, 2006;Marko et al, 2004). In addition, substitutions may affect food safety when species are replaced by others that exhibit potential health risks (Cline, 2012;Galimberti et al, 2013;Handy et al, 2011;Triantafyllidis et al, 2010).…”

“…Among DNA markers, a region of the cytochrome C oxidase subunit I (COI) has been widely used as a DNA barcoding sequence and has demonstrated high sensitivity and reliability in the differentiation of species, including those that are closely related (Ardura et al, 2010;Carvalho, Neto, Brasil, & Oliveira, 2011a;Hebert, Cywinska, Ball, & deWaard, 2003a;Hebert, Ratnasingham, & deWaard, 2003b;Pereira, Pazian, Hanner, Foresti, & Oliveira, 2011b). The COI has also been successfully used in the identification of processed fish, elucidating various substitutions and commercial fraud cases (Barbuto et al, 2010;Carvalho et al, 2011a;Cawthorn et al, 2012;Galimberti et al, 2013;Hanner, Becker, Ivanova, & Steinke, 2011;Huxley-Jones et al, 2012).…”

FISH-BOL, A Case Study for DNA Barcodes

The FISH-BOL campaign was initiated in 2005, and currently has barcoded for the cytochrome c oxidase subunit I (COI) gene about 8,000 of the 31,000 fish species currently recognised. This includes the great majority of the world's most important commercial species. Results thus far show that about 98% and 93% of marine and freshwater species, respectively, are barcode distinguishable. One important issue that needs to be more fully addressed in FISH-BOL concerns the initial misidentification of a small number of barcode reference specimens. This is unsurprising considering the large number of fish species, some of which are morphologically very similar and others as yet unrecognised, but constant vigilance and ongoing attention by the FISH-BOL community is required to eliminate such errors. Once the reference library has been established, barcoding enables the identification of unknown fishes at any life history stage or from their fragmentary remains. The many uses of the FISH-BOL barcode library include detecting consumer fraud, aiding fisheries management, improving ecological analyses including food web syntheses, and assisting with taxonomic revisions.
