“…This is facilitated by the fact that seafood is a highly traded commodity with a very diverse range of closely related and visually similar species which undergo procedures and processing, reducing or eliminating the morphological traits used for identification, such as heading, filleting or value-added processing (Pineiro et al 2001;Marko et al 2004;Chen et al 2012;Mohanty et al 2013;Jennings et al 2016;Tagliavia et al 2016). This coupled with the fact that seafood has become a limited resource and experiences price pressures, provides a substantial market for substitution and mislabeling within the industry (Jacquet and Pauly 2008;Miller and Mariani 2010;Heyden et al 2010;Chen et al 2012;Galal-Khallaf et al 2014;Hurst et al 2014;Mueller et al 2015;Stamatis et al 2015;.…”

Food fraud is an intentional act for economic gain. It poses a risk to food integrity, the economy, public health and consumers' ethics. Seafood is one commodity which has endured extensive fraudulent activity owing to its increasing consumer demand, resource limitations, high value and complex supply chains. It is essential that these fraudulent opportunities are revealed, the risk is evaluated and countermeasures for mitigation are assigned. This can be achieved through mapping of the seafood supply chains and identifying the vulnerability analysis critical control points (VACCP), which can be exposed, infiltrated and exploited for fraudulent activity. This research systematically maps the seafood supply chain for three key commodities: finfish, shellfish and crustaceans in the United Kingdom. Each chain is comprised of multiple stakeholders across numerous countries producing a diverse range of products distributed globally. For each supply chain the prospect of fraud, with reference to species substitution, fishery substitution, illegal, unreported and unregulated substitution, species adulteration, chain of custody abuse, catch method fraud, undeclared product extension, modern day slavery and animal welfare, has been identified and evaluated. This mapping of the fraudulent opportunities within the supply chains provides a foundation to rank known and emerging risks and to develop a proactive mitigation plan which assigns control measures and responsibility where vulnerabilities exist. Further intelligence gathering and management of VACCPs of the seafood supply chains may deter currently unknown or unexposed fraudulent opportunities.

“…The substitution of economic aquatic products also results in health hazards, economic fraud and illegal trade of protected species. And it has become an extremely serious problem in the economic aquatic products industry and is spreading world widely (GalalKhallaf, Ardura, Mohammed-Geba, Borrell, & Garcia-Vazquez, 2014). For example, substitutions have been detected in the markets of North America (Wong & Hanner, 2008), New Zealand (Smith, McVeagh, & Steinke, 2008) South Africa (Cawthorn, Steinman, & Witthuhn, 2012), and Egypt (Galal-Khallaf et al 2014).…”

Hence, the detection of substituted species, as well as increasing the public awareness of the nutrition level and shifting consumer attitudes toward products, has become an important topic in the aquatic products industry.…”

“…Many DNA barcoding researches has demonstrated that COI contains sufficient variation to accurately identify a large variety of animals, including both freshwater (Hubert et al 2008) and marine aquatic organisms ( Rock et al 2008;Spies, Gaichas, Stevenson, Orr, & Canino, 2006;Ward, Holmes, White, & Last, 2008;Ward, Zemlak, Innes, Last, & Hebert, 2005), to the species level (Waugh, 2007). Especially, COI gene barcoding has provided numerous successful examples demonstrating its reliability for the identification of fish, such as tuna (Lowenstein et al 2010;Terol, Mascarell, Fernandez-Pedrosa, & Perez-Alonso, 2002), flatfish (Espineira, Gonzalez-Lavin, Vieites, & Santaclara, 2008;Terol et al 2002), anchovy (Jerome et al 2008), and catfish (Wong et al 2011), as well as other economic aquatic species (Ardura, Linde, Moreira, & Garcia-Vazquez, 2010;Galal-Khallaf et al 2014). At present, the barcoding of common economic aquatic products has become increasingly important in the supervision of the market trade (Carvalho et al 2011).…”

“…Even some countries such as Egypt and South Africa also have been doing mithocondrial DNA to fish in some supermarkets. This is done to keep out of concern because of the high incidence of substitution and regulation of the circulation of species of fish, including grouper at the International level (Galal-Khallaf et al 2014) and (Cawthorn et al 2012). However, the Epinephelus spp.…”

Abstract. Jefri E, Zamani EP, Subhan B, Madduppa HH. 2015. Molecular phylogeny inferred from mitochondrial DNA of the grouper Epinephelus spp. in Indonesia collected from local fish market. . Groupers are widely distributed in the tropical and subtropical coastal waters, and are globally one of the most commercially important groups of marine fish, commanding high market price and are being heavily targeted in fisheries. Over fishing in Indonesia becomes a pivotal factor, which is seriously threatening the grouper biodiversity, as separate catch statistics are not reported for most species, and landings are often summarized as 'serranids' or 'groupers'. This lack of species-specific catch data is due to the difficulty of identifying many of the species. The focus of this study was the tracking of molecular phylogeny of Epinephelus spp. of the family Serranidae. DNA amplification using mitochondrial cytochrome oxidase I resulted in 526-base pairs long sequences all samples. A total of seven species were characterized that are (Epinephelus areolatus, E. merra, E. fasciatus, E. longispinis, E. coioides, E. ongus and E. coeruleopunctatus). All of which were found to belong to 7 different clades in the constructed phylogenetic tree. E. ongus is genetically closest to E. coeruleopunctatus with genetic distance 0.091 (9%), whereas the farthest genetic distance was successfully identified between E. ongus and E. merra with genetic distance 0.178 (18%). Migration activity on spawning and movement of larvae that are affected by Indonesian Through flow suspected as the cause of the closeness between species grouper Epinephelus spp. in the phylogeny tree from several Indonesian seas, although information about the location and time of Epinephelus spp. spawning activity sometimes difficult to obtain certainty. Fish identification using molecular phylogenetic approach has been successfully applied in this study. It seems need further application on this method to avoid misidentification and due to high variety of species landing at local fish market. Nevertheless, this study would be an important data in the genetic management for the sustainable conservation and trade of grouper (Epinephelus spp.) in Indonesia.
