Molecular markers have contributed to species authentication by flagging mislabeling and the misidentification of commercial landings. Such tools are of great value since the market substitution of fish of lower value for highly commercialized species is expected to become more pronounced due to a shortage of natural stocks.
Here we report on the molecular identification 4results from processed fish products (i.e. fillets) and whole fishes sold in Brazilian markets under the common name surubim (Pseudoplatystoma spp.).
DNA barcoding revealed the incorrect labeling of around 80% of all samples analyzed, with mislabeling being more pronounced within fillets rather than whole fish.
To our knowledge, this is the first report correlating the rate of fraud with processed fish products. The establishment of an official list of acceptable common names for freshwater fish and seafood is urgently needed in Brazil for further trade regulations to take place.
分子标记通过标记商业捕捞中的错误标签和误认，有助于物种鉴定。由于天然种群短缺，预计低价值鱼类对高商业化物种的市场替代将更加明显，此类工具具有重要价值。
在此，我们报告了巴西市场上以“苏鲁比姆”（Pseudoplatystoma spp.）之名销售的加工鱼产品（即鱼片）和整条鱼的分子鉴定结果。
DNA条形码显示，在所有分析样本中，约80%存在标签错误，鱼片的标签错误比整条鱼更为明显。
据我们所知，这是第一份将欺诈率与加工鱼产品相关联的报告。巴西迫切需要建立一份淡水鱼和海鲜可接受通用名称的官方清单，以便进一步实施贸易监管。
