ABSTRACT In Brazil, a large quantity of shrimps captured through commercial fishing is marketed as labelled frozen packages following current legislation (Normative Instruction No. 23, of 20 August 2019). This study tested the possibility of errors in species identification (forensic analysis) listed on the labels of packages sold in the country by using mitochondrial molecular marker. Labelled samples (packages) were acquired in supermarkets in different states of Brazil, and specimens were selected on the basis of apparent morphological differences for analysis. DNA was extracted from each specimen selected from packages, with 16S marker amplification, DNA purification and sequencing. Generated sequences were compared with those available in GenBank using BLAST and grouped by neighbour‐joining method. Mislabelling was detected regarding species identification. Specimens of Pleoticus muelleri (Solenoceridae) were labelled as ‘pink shrimp’, which should be some species from the genus Penaeus (Penaeidae). Furthermore, representatives of Artemesia longinaris and P. muelleri were found under the label ‘seabob shrimp’ (i.e., Xiphopenaeus spp.). On the other hand, most of the samples were in accordance with the regulations regarding species identification. Our results indicated that some packages (8.8%) do not comply with the regulations. This finding means lack of precision about what is being commercialized and suggests the necessity to propose adjustments in‐line with consumer rights and species conservation.
