Identification of three Ictalurus species in Mexico using Cytochrome Oxidase I gene sequencing.

Mexico contributes with nearly 10% of the world fish diversity (CONABIO, 2014). 543 out of 3000 species are subject to commercial exploitation in the country (SAGARPA, 2013). However, it has been proposed that 86% of the species on Earth and 91% in the ocean still need to be described (Mora et al., 2011). Channel catfish Ictalurus punctatus is one of the Mexican freshwater fishes with the highest presence in American aquaculture. For its exploitation on aquaculture and fisheries, channel catfish have been introduced in 20 states of the Mexican territory (Lara-Rivera et al., 2015). Reservoirs are common receptacles for fry and adult releases in order to promote local subsistence fishing. Since there are no reports of neither prior nor subsequent studies of these releases, it is uncertain if wild and domestic populations have mixed at some point. On the other hand, fishermen are not familiar with the taxonomical distinctive characteristics of the different species of the genus Ictalurus, which leads to misidentification of fish from the net and all the way to the market. In order to identify a specimen, there is need of two things: first, a specialized taxonomist, and second, specimens in an ideal state of preservation. DNA barcoding has proven to be a powerful tool for rapid, non-morphological and accurate species identification and discovery (Ward et al., 2005). Sequencing of a 648 bp region from the Cytochrome Oxidase 1 (COI) region allows comparison and identification of species based on similarities among related groups (Clare et al., 2007). Among the most useful applications of DNA barcoding are identification of fish products and sub-products (such as fillets, nuggets and conserves), mislabeled products (Jacquet & Pauly, 2008; Wong & Hanner, 2008; Galal-Khallaf et al., 2014) and recognition of endangered or potentially risky species (Galimberti et al., 2013; Quinto et al., 2016). There is very few information regarding channel catfish distribution on Mexican continental waters and nowadays, I. punctatus is considered to be an invasive species in Mexico (Gonzalez et al., 2014), since the production began from fish imported from the USA instead of Mexican native populations. Therefore, the aim of the present work was the molecular identification of Mexican catfish using a DNA barcoding approach.

A total of 93 samples were used for the analysis (Table 1); 17 samples representing the most important aquaculture farms in Mexico, 70 samples were obtained from free-living catfish from 5 reservoirs, 5 rivers, and 1 lake. Additionally, 5 commercial samples, labeled as "catfish" were used for a comparative analysis. Samples consisted of anal and adipose fins. DNA was extracted using the commercial kit GenElute Mammalian Genomic DNA Miniprep (SIGMA Aldrich[R]) following the directions provided by the manufacturer. DNA integrity was verified on 1.5% agarose gels. DNA concentration was calculated using a Nano Drop 2000 C spectrophotometer (Thermo Scientific v 1.1). In order to amplify 651 bp fragment from the 5' end of mitochondrial COI gene, PCR reactions were conducted using primer cocktails C_FishF1t1 and C_FishR1t1 as described by Ivanova et al. (2007) and Wong et al. (2011). The amplification reactions were performed in a total volume of 10 [micro]L and included 0.5X Buffer (Promega [R]), 0.2 mM of each deoxynucleotide triphosphate (dNTPs), 2.5 mM MgCh, 0.2 pmol of each primer, 100 ng of genomic DNA, and 1.2 U [micro]L"1 Taq DNA polymerase (Promega[R]). The reactions were conducted using an MJ Research 3130 Thermal Cycler under the following conditions: an initial denaturation at 95[degrees]C for 2 min; 35 cycles of 95[degrees]C for 30 s, 52[degrees]C for 40 s and 72[degrees]C for 1 min; and concluded with a final elongation step of 72[degrees]C for 10 min followed by a hold at 4[degrees]C. Amplified PCR products were subsequently cleaned by the Exo-SAP method (Dugan et al., 2002); 1 [micro]L of PCR product and 0.5 [micro]L EXO SAP-IT (Affymetrix) were incubated for 15 min at 37[degrees]C and 80[degrees]C for 15 min. Thereafter, 1 [micro]L of each purified PCR product was labeled using the BigDye Terminator v 3.1 Cycle Sequencing Kit (Applied Biosystems Inc., CA, USA); 4.5 [micro]L of sterile miliQ water, 2.0 [micro]L of BigDye Sequencing Buffer (400 mM Tris-HCl pH 9.0 and 10 mM MgCh), 2.0 [micro]L of Ready Reaction RR-100 and 0.2 pmol Forward Primer F2_t1 for a total reaction mixture of 10 [micro]L. A sequencing reaction program was run as follows: an initial denaturation at 96[degrees]C for 1 min; 25 cycles of 96[degrees]C for 10 s, 50[degrees]C for 05 s and 60[degrees]C for 4 min, followed by a hold at 4[degrees]C. Then, 5 [micro]L were taken from the resulting sequencing reaction and added with 22.5 [micro]L and 5.0 [micro]L SAMTM and BigDyeR XTerminatorTM (Applied Biosystems Inc., CA, USA) solutions respectively, incubated with agitation of 1000 rpm for 30 min at 24[degrees]C, then centrifuged at 10000 for 10 min and supernatant transferred to a 96 well plate and sequenced on an ABI 31306l Genetic Analyzer (Applied Biosystems Inc., CA, USA). Sequences were edited using Chromas Lite v 2.1.1 (Technelysium, Pty Ltd.). Voucher sequences from GenBank, reference sequences from BOLD (Altschul et al., 1990) databases and consensus sequences of each species generated from this study were compared and aligned using the CLUSTALW software on MegAlign Pro (DNASTAR Inc., Madison, WI). Sample identification based on the sequence similarity approach was carried out using two databases; BOLD and GenBank. The highest percent pairwise identity of the consensus sequence from each species blasted (BLASTN) against NCBI were compared to the percent specimen similarity scores of the consensus sequence from each species within the BOLD-IDS (BOLD Identification System) (Ratnasingham & Hebert, 2007). As commonly applied in DNA barcoding, sequence divergences were estimated by the Kimura 2-parameter substitution model and a phylogenetic tree was constructed with MegAling using an improved version of the Neighbor-Joining algorithm of Satou and Nei (Gascuel, 1997). The robustness of the maximum parsimony tree was assessed by performing bootstrapping analysis with 1000 replicates, and gaps removed by complete deletion (Felsenstein, 1985).

Table 1 shows the comprehensive barcoding identification results based on GenBank or BOLD databases. Both databases revealed identity in the range of 96-100% for consensus sequences of three species (Ictalurus punctatus, I. furcatus, and I. lupus). GenBank-based identification for all species yielded an alignment E-value of 0.0.BOLD-IDS results were in agreement with GenBank results in the identification of these species, yielding 100% identity. However, some entrees on FISH-BOLD were marked as "private" and therefore, even when there could be a more reliable match for the target sequence, it cannot be identified at this moment. All domestic samples used for aquaculture were positively identified as I. punctatus (Table 1). Concerning free-living individuals, most samples were also identified as channel catfish, with the exception of two individuals from Pilon and Corona Rivers in Tamaulipas, identified as I. lupus. With respect to commercial fish, only two samples matched I. punctatus COI sequence: a sample from Panuco River, a natural border between the Mexican States Tamaulipas and Veracruz, was identified as channel catfish, same as a fish purchased from a random fish market located on the center of the State of Tamaulipas. At that same location, another specimen was identified as I. lupus. A fish collected at Chapala Lake, in the State of Jalisco was also identified as I. lupus. Another related species, I. furcatus was found at Champayan Lagoon, located southern state in Tamaulipas.

Identification of channel catfish species in Mexico has several connotations. First of all, it can be inferred that, in spite of the lack of attention that has been given to the species production, aquaculture is based on I. punctatus and not misleading species. An accurate and reliable identification of channel catfish provides a powerful tool for further market analysis of fish products and sub-products. It has been established that almost 25% of fish products in the United States are mislabeled (Wong & Hanner, 2008); most products are intentionally sold as more expensive species. Channel catfish, in particular, has faced great competition against bassa fish (Pangasius spp.) since it is produced at a much lower cost. However, the low-quality requirements of bassa fish make it a potential hazard to health and unfair competition for the channel catfish industry. In the present report, it was observed that when looking for "catfish", different species are available on fish markets. I. lupus and I. furcatus were presented as alternatives for channel catfish consumption but are likely dueto the local availability of fish or a lack of awareness from the consumers. The appropriate identification of species constitutes one of the main concerns regarding population management, such as biodiversity monitoring (Groves et al., 2002; Hajibabaei et al., 2007), recognition of mating and migratory behaviors (Sawyer et al., 2009), and population genetics by providing signals of the extent and nature of population divergences and facilitating comparative studies of population diversity (Taylor et al., 2003; Hebert et al., 2004). Taxonomic identification is usually dependent on the existence of a good quality specimen and the availability of a skilled professional. Molecular identification of wild specimens could be of utmost importance for the study of wild populations. Not only in the present it was possible to verify the reported distribution of Ictalurus species in Mexico such as the case of I. furcatus and I. punctatus on Bravo and Panuco rivers (Garcia de Leon et al., 2005), but we can also report the presence of freeliving channel catfish, Ictalurus punctatus, on eight novel locations within Mexican territory: "Gustavo Diaz Ordaz", "Republica Espanola", "Ramiro Caballero", "Vicente Guerrero" and "La Boquilla" reservoirs and Purificacion, Pilon and Corona rivers (Table 2).

On the other hand, I. furcatus, previously reported in Bravo and Yaqui River (Cuvier & Valenciennes, 1829) was now found on Champayan Lagoon, more than 400 km to the south. Moreover, I. lupus, previously reported in Balsas River and Ixtla River (Jordan & Snyder, 1900), was found at 3 novel locations: Pilon River, Corona River, and Chapala Lake. As it can be noted, Ictalurus species have expanded their original range. This can be attributed to the success of a growing industry. However, it should be noted that undocumented introductions, transportation, and releases could have a negative impact on recognized wild catfish populations. Channel catfish is considered as an invasive species on present days (Gonzalez et al., 2014) and any species with a little survival potential could be dangerous on a new ecosystem. Notwithstanding, the channel catfish should be rather seen as a species with a huge productive potential instead of a threat, while new tools emerge to greatly facilitate our understanding and ability to leverage its maximum potential.

The effectiveness of DNA barcoding was ascertained for channel catfish populations in Mexico. It was verified that aquaculture industry uses only the species I. punctatus. A wider distribution range was observed for three Ictalurus species. A total of 12 novel sites are here reported for I. punctatus, I. furcatus and I. lupus. When commercial samples were analyzed, it was found that I. lupus and I. furcatus were sold as generic "catfish", so it is proposed that molecular identification by DNA barcoding represents a powerful tool in the study of catfish populations and subproducts.
