Enhancing Wildlife Trade Monitoring in the European Union-No Need to Reinvent the Wheel.

Biodiversity loss is mainly driven by changes in land use and overexploitation, with the commercial trade of wildlife being a smaller but still important contributor to resource depletion and species decline. The trade-including live animals, plants, fungi, and derived products-is a major economic sector valued at US$145-220 billion annually. The European Union (EU) is a key market, importing wildlife products worth approximately €100 billion.

Lipidomic signatures in Octopus vulgaris arm muscle reveal geographic variation along the Iberian Atlantic Coast.

The common octopus (Octopus vulgaris) is a highly valued seafood species, whose flavour and palatability are often linked to its geographic origin. However, globalized supply chains have increased the risk of mislabelling. Lipid metabolism in marine organisms is shaped by environmental conditions, then lipidomics offers a promising tool for origin authentication.

Non-additive phospholipidomic responses to ocean warming and acidification drive intraspecific variation in cell membrane vulnerability in a marine ectotherm.

The lipidome is fundamental to the good functioning of cells and organisms. However, its role in species acclimatisation and adaptation to global changes remains overlooked. Investigating intraspecific variation in lipidome responses to combined global change drivers is therefore paramount to predict species' vulnerability in future oceans.

Acute Effect of Short-Term Benzocaine Anesthesia on the Skin Mucus Microbiome of Atlantic salmon ().

Routine aquaculture practices such as capture, transportation, and handling can disrupt the relationship between commensal and opportunistic bacteria in the fish skin microbiome. Anesthetic baths are a common welfare practice in aquaculture to reduce stress during handling.

How Significant Are Marine Invertebrate Collagens? Exploring Trends in Research and Innovation.

This review is focused on the research, innovation and technological breakthroughs on marine invertebrate collagens and their applications. The findings reveal that research dates back to the 1970s, and after a period of reduced activity, interest in collagens from several marine invertebrate groups was renewed around 2008, likely driven by the increased commercial interest in these biomolecules of marine origin. Research and development are predominantly reported from China and Japan, highlighting significant research interest in cnidarians (jellyfish), echinoderms (sea cucumbers, sea urchins and starfish), molluscs (squid and cuttlefish) and sponges.

Fatty Acids of European Sardine () White Muscle Can Discriminate Geographic Origin Along the Iberian Atlantic Coast.

The European sardine () ranks among the most valuable species of Iberian fisheries, and the accurate tracing of its geographic origin, once landed, is paramount to securing sustainable management of fishing stocks and discouraging fraudulent practices of illegal, unreported, and unregulated (IUU) fishing. The present study investigated the potential use of white muscle fatty acids (FAs) to successfully discriminate the geographic origin of samples obtained in seven commercially important fishing harbors along the Iberian Atlantic Coast. While 35 FAs were identified using gas chromatography-mass spectrometry in the white muscle of , the following, as determined by the Boruta algorithm, were key for sample discrimination: 14:0, 22:6-3, 22:5-3, 18:0, 20:5-3, 16:1-7, 16:0, and 18:1-7 (in increasing order of relevance).

An Updated Review of the Marine Ornamental Fish Trade in the European Union.

Wild-caught fish from coral reefs, one of the most threatened ecosystems on the planet, continue to supply the marine aquarium trade. Despite customs and veterinary checks during imports, comprehensive data on this global industry remain scarce. This study provides consolidated data on the largest import market by value, the European Union (EU): a 24-million-euro annual trade value, detailing the main exporting and importing countries, as well as the species and families of the 26 million specimens imported between 2014 and 2021.

Combined Use of Fatty Acid Profiles and Elemental Fingerprints to Trace the Geographic Origin of Live Baits for Sports Fishing: The Solitary Tube Worm (, Annelida, Onuphidae) as a Case Study.

Delle Chiaje, 1841 (Annelida, Onuphidae) is one of the most exploited polychaete species in European waters, particularly in Ria de Aveiro, a coastal lagoon in mainland Portugal, where the overexploitation of this resource has led to a generalized decline of local populations. In an attempt to reduce the impact of harvesting, several management actions were implemented, but illegal poaching still fuels a parallel economy that threatens the sustainable use of this marine resource. The present study evaluated the combination of fatty acid profiles and elemental fingerprints of the whole body and jaws, respectively, of collected from four harvesting locations within Ria de Aveiro in order to determine if their geographic origin could be correctly assigned post-harvesting.

Fatty Acid Profile and and sp. Load of Wild-Caught Seaweed Fly (Haliday, 1838) (Diptera: Anthomyiidae).

World aquaculture is expected to continue to grow over the next few decades, which amplifies the need for a higher production of sustainable feed ingredients for aquatic animals. Insects are considered good candidates for aquafeed ingredients because of their ability to convert food waste into highly nutritional biomass. However, commercially available terrestrial insect species lack long-chain polyunsaturated fatty acids (LC-PUFAs), which are essential biomolecules for marine cultured species.

Fatty Acid Profiling as a Tool for Fostering the Traceability of the Halophyte Plant and Contributing to Its Nutritional Valorization.

, commonly known as glasswort or sea asparagus, is a halophyte plant cultivated for human consumption that is often referred to as a sea vegetable rich in health-promoting -3 fatty acids (FAs). Yet, the effect of abiotic conditions, such as salinity and temperature, on the FA profile of remains largely unknown. These factors can potentially shape its nutritional composition and yield unique fatty acid signatures that can reveal its geographical origin.

Effects of HO pretreatment on the elemental fingerprints of bivalve shells and their implications for the traceability of geographic origin.

The fraudulent mislabelling of seafood geographic origin has been growing due to complex supply chains and growing consumer demand. To address this issue, seafood traceability tools, such as those based on elemental fingerprints (EF) of bivalve shells, have been successfully used to confirm their harvesting location. However, despite the usefulness of these methodologies, there is still room for optimization.

Marine Animal Co-Products-How Improving Their Use as Rich Sources of Health-Promoting Lipids Can Foster Sustainability.

Marine lipids are recognized for their-health promoting features, mainly for being the primary sources of omega-3 fatty acids, and are therefore critical for human nutrition in an age when the global supply for these nutrients is experiencing an unprecedent pressure due to an ever-increasing demand. The seafood industry originates a considerable yield of co-products worldwide that, while already explored for other purposes, remain mostly undervalued as sustainable sources of healthy lipids, often being explored for low-value oil production. These co-products are especially appealing as lipid sources since, besides the well-known nutritional upside of marine animal fat, which is particularly rich in omega-3 polyunsaturated fatty acids, they also have interesting bioactive properties, which may garner them further interest, not only as food, but also for other high-end applications.
