“…Some of these have already been utilized to reveal discrepancies in reported marine mammal bycatch, to determine the magnitude of trade and to develop kits that rapidly identify marine mammal species in situ in Asian markets (Baker et al, 2006(Baker et al, , 2007Lukoschek et al, 2009;Lo et al, 2013). These tools, designed specifically for non-specialists, will allow quantitative data collection both on type and volume of marine mammal parts in Asian markets.…”

In Asia many marine mammal species are consumed as food or for other purposes. The prevalence of this exploitation appears to increase from west to east. An escalating use of marine mammals and the emergence of commercialization of a trade in marine mammals is supported by:• Regular documentation of both open and covert trade;• A shift in focus in some diminishing traditional hunts to other marine mammal species;• A possible revival in some targeted hunts, which had previously ceased;• The recent implication of some cultures, which have little history of marine mammal consumption previously, in targeted hunts; and• The growing importation of marine mammal parts from outside of Asia.The factors that may drive marine mammal use include population reductions in species that have been traditionally targeted; diminishing returns from traditional fisheries; and an increase in market demand for marine mammal products. Lessons from similar studies in terrestrial wildlife trade will better focus future studies of marine mammal use in Asia.

“…Most species are used for human consumption, but some for bait in fisheries (Mintzer et al, 2018). In Taiwan, despite the sale of bycaught cetaceans being illegal, the meat of hundreds of bycaught individuals was once sold in local markets (Sui, 2014), however, recent advances in forensic surveillance have since curtailed most trade (Lo et al, 2013). Information for China is anecdotal and limited, e.g., Jefferson and Van Waerebeek (2002) presented photographic evidence of bycaught common dolphins landed at fish markets of Putian, Fujian Province.…”

Wild animals are captured or taken opportunistically, and the meat, body parts, and/or eggs are consumed for local subsistence or used for traditional purposes to some extent across most of the world, particularly in the tropics and subtropics. The consumption of aquatic animals is widespread, in some places has been sustained for millennia, and can be an important source of nutrition, income, and cultural identity to communities. Yet, economic opportunities to exploit wildlife at higher levels have led to unsustainable exploitation of some species. In the literature, there has been limited focus on the exploitation of aquatic non-fish animals for food and other purposes. Understanding the scope and potential threat of aquatic wild meat exploitation is an important first step toward appropriate inclusion on the international policy and conservation management agenda. Here, we conduct a review of the literature, and present an overview of the contemporary use of aquatic megafauna (cetaceans, sirenians, chelonians, and crocodylians) in the global tropics and subtropics, for species listed on the Appendices of the Convention on the Conservation of Migratory Species of Wild Animals (CMS). We find that consumption of aquatic megafauna is widespread in coastal regions, although to varying degrees, and that some species are likely to be at risk from overexploitation, particularly riverine megafauna. Finally, we provide recommendations for CMS in the context of the mandate of the Aquatic Wild Meat Working Group.

“…Hence, a comparative study was carried out for all eight combinations of antibodies indicated in Table 2. According to the study of Lo et al, the MG content in pork is approximately 2 mg g −1 [31]. Therefore, the ELISA characteristics of the selected pairs of antibodies indicate their suitability for the development of the LFIA with the, practically, demanded sensitivity.…”

Immunochromatographic Detection of Myoglobin as a Specific Biomarker of Porcine Muscle Tissues in Meat Products

et al. 2020

View full text Add to dashboard Cite

An immunochromatographic detection of myoglobin (MG) as a specific marker of porcine muscle tissue has been developed. The method is based on the sandwich lateral flow immunoassay (LFIA) with gold nanoparticles (AuNPs) as a label. The developed test system determines MG with a detection limit of 5 ng mL−1 within 15 min. A specific determination of porcine MG and no cross-reactivity with MG from other tested mammals and bird species was demonstrated. The test system is able to detect pork additives, as low as 0.01% (w/w), in minced beef. A technique of MG extraction from muscle tissue has been proposed which allows for rapid and efficient MG extraction from meat samples (within 20 min). The developed test system can serve as an effective means of controlling the authenticity and quality of meat products.
