| Summary: | The seasonal occurrence of the Black Sea jellyfish <i>Blackfordia virginica</i> Mayer, 1910 blooms is a reason of concern in the Guadiana estuary in the South of Portugal (South-West Europe), causing considerable economic and ecological impacts to fisheries. Due to jellyfish biochemical properties, they may represent an opportunity as an alternative food source for humans. In this context, this work evaluated the nutritional profile of <i>B. virginica</i> (proximate composition, amino acids, minerals, and fatty acids methyl ester content). <i>Blackfordia virginica</i> biomass may be adequate for human consumption, as it has nutritional properties resembling other edible jellyfish species, with relevant levels of minerals, moderate content in crude protein, low-fat content, and a low energetic value. The high Cd levels in the biomass of <i>B. virginica</i> from the Guadiana Estuary may compromise its safety as a food source. Moreover, if these jellyfishes are proven as an edible invasive species, their management through fisheries should evaluate the cost effectiveness of investments. |
