“…DNA barcodes [156,157] and Radio Frequency Identification Device (RFID) tags have been used for authentication and tracking of seafood in commerce [298,305,313,340,341,342]. However, there is a need for rapid handheld instruments that can be used by fishers, wholesalers, and retailers.…”

“…However, there is a need for rapid handheld instruments that can be used by fishers, wholesalers, and retailers. Tracking and authentication technologies, commodity tracking systems, and the development of regulatory protocols/agreements show promise that the seafood market system can be traceable and accurately assessed in the future [340,343]. …”

An Updated Review of Ciguatera Fish Poisoning: Clinical, Epidemiological, Environmental, and Public Health Management

et al. 2017

Ciguatera Fish Poisoning (CFP) is the most frequently reported seafood-toxin illness in the world. It causes substantial human health, social, and economic impacts. The illness produces a complex array of gastrointestinal, neurological and neuropsychological, and cardiovascular symptoms, which may last days, weeks, or months. This paper is a general review of CFP including the human health effects of exposure to ciguatoxins (CTXs), diagnosis, human pathophysiology of CFP, treatment, detection of CTXs in fish, epidemiology of the illness, global dimensions, prevention, future directions, and recommendations for clinicians and patients. It updates and expands upon the previous review of CFP published by Friedman et al. (2008) and addresses new insights and relevant emerging global themes such as climate and environmental change, international market issues, and socioeconomic impacts of CFP. It also provides a proposed universal case definition for CFP designed to account for the variability in symptom presentation across different geographic regions. Information that is important but unchanged since the previous review has been reiterated. This article is intended for a broad audience, including resource and fishery managers, commercial and recreational fishers, public health officials, medical professionals, and other interested parties.

“…Policymakers cannot ignore how the expanding adoption of DNA barcoding technology is changing the way cases of intentional mislabelling and fraud are detected and prosecuted. The innovation of hardware such as 'hand-held' devices with DNA identification capabilities could democratize the authentication process and reduce the time necessary for species identification (see Ulrich et al, 2015). Yet, the ability for hand-held devices to become a widely acceptable way to authenticate species hinges on the existence of a globally accessible, expert-authenticated database of genetic information and other species identifiers, which are part of the DNA barcoding methodology.…”

“…Since the cost of feed, environment decline, disease outbreak and wages have been major constraints to the development of the industry; the provision of an alternative novel economic grouper strain that will be able to enhance sustainability of grouper farming is of interest to the industry. Giant grouper and tiger grouper are both economically important fish (Ulrich, John, Barton, Hendrick, Fries & Paul ) however, their growth rates are different. In culture conditions the giant grouper typically has a higher growth rate than tiger grouper.…”

Groupers are economically important for aquaculture in Thailand. A novel hybrid grouper (Epinephelus lanceolatus 9 Epinephelus fuscoguttatus) has been successful cross-bred; therefore, the present work aimed to assess the hybrid's traits. The growth performance, strength and tolerance to a pathogenic bacterial infection of this hybrid were compared with its parent species, tiger grouper and giant grouper. The results of all measured growth parameters indicated that the hybrid strain grew fastest followed by giant and tiger grouper respectively. The expressions of the growth-related genes, insulin-like growth factor (IGF) I and II, were also analysed in fish muscle and liver which are the main target organs in fish growth regulation. Among tested species, similar expression patterns of IGF-I and IGF-II were detected in both organs. The levels of these genes in liver and muscle of hybrid and giant grouper were higher than those of tiger grouper comparable with the growth manner. After challenge with Vibrio vulnificus, the immunological parameters, clearance time of Vibrio in haemolymph and survival was measured to verify the fish immunity. Leucocyte number, lysozyme activity and the ability to eliminate the pathogen were very high in hybrid and giant grouper while these parameters were lower in tiger grouper. Correspondingly, the mortality rate of tiger grouper was higher than others and % survival at the end of observation time (15 days post challenge) was lowest in infected tiger grouper. Altogether, the results suggested that the hybrid grouper has desirable traits that will improve cultured grouper.
