Article Abstract
Although seafood species identification has traditionally relied on morphological analysis, sometimes this is difficult to apply for the differentiation among penaeid shrimps owing to their phenotypic similarities and to the frequent removal of external carapace during processing. The objective of this review is to provide an updated and extensive overview on the molecular methods for shrimp and prawn species authentication, in which several omics approaches based on protein and DNA analysis are described. DNA-based methods include the amplification by PCR of different genes, commonly the mitochondrial 16S ribosomal RNA and cytochrome oxidase I genes. A recently described method based on RFLP coupled to PCR turned out to be particularly interesting for species differentiation and origin identification. Protein analysis methods for the characterization and detection of species-specific peptides are also summarized, emphasizing some novel proteomics-based approaches, such as phyloproteomics, peptide fragmentation, and species-specific peptide detection by HPLC coupled to multiple reaction monitoring (MRM) MS, the latter representing the fastest method described to date for species authentication in food.
A new freshwater prawn, Macrobrachium ngankeeae n. sp., is described from two rivers in the Kaimana Regency on the southern coast of Papua Barat Province, Indonesia.
* Aquaculture is an important yet underrepresented sector in NAPs, using significant antibiotics compared to human and terrestrial animal applications, and it requires tailored strategies due to its complexity and global trade implications.
* To enhance NAPs for aquaculture, it’s crucial to recognize its diversity and engage stakeholders across the value chain, including health services, while ensuring policies consider the interconnectedness of human, animal, and environmental health.
The study focuses on the giant red shrimp, a valuable marine species, emphasizing the importance of understanding its biology for effective conservation and management strategies.
Researchers developed and characterized new microsatellite markers through next-generation sequencing, identifying 19 polymorphic loci after testing 58 candidates across a global panel of shrimp individuals.
The identified loci will aid in parentage analysis and understanding the population structure and connectivity of the giant red shrimp across different geographical areas, particularly between exploited and unexploited environments.
The best practice for killing decapod crustaceans lacking a centralized ganglion has been debated for a century. Currently, there is a movement away from live boiling towards electrocution and mechanical splitting or spiking, which are efficient in the large commercial setting but may be unavailable and impractical for small decapods such as shrimp and prawn in the small-scale setting of, e.g.
Background: The invasion of non-native species into ecosystems is a growing human-induced problem. To control their spread and population growth, knowledge is needed on the factors that facilitate or impede their invasions. In animals, traits often associated with invasion success are high activity, boldness, and aggression.
