Re-evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2. [PDF]

EFSA J
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Environmental Factors Influencing Metal Concentrations in Scomber colias Along the Canary Islands. [PDF]

Biol Trace Elem Res
Abstract A total of 140 specimens of Scomber colias were collected from the Canary archipelago waters during the first semester of 2021, with 20 samples from each of the seven main islands. After analyzing the concentrations of metals (Al, Zn, Cd, Pb, Fe, and Cu) with ICP-OES, significant variations were observed among islands, with specimens

Interdecadal variations of the mercury content in Scomber colias in Canary Islands

Environmental Science and Pollution Research, 2022
Mercury is a very dangerous toxic metal that bioaccumulates very easily in organisms, and it migrates through the food web. The specimens studied in this study were Scomber colias. In the results obtained for the years 1973, 1992, and 2021, the concentration of mercury has been decreasing considerably over the decades, starting with 0.23 ± 0.04 mg/kg ...

MultiBarcodeTools: Easy selection of optimal primers for eDNA multi‐metabarcoding

Environmental DNA, Volume 5, Issue 6, Page 1793-1808, November 2023., 2023
Metabarcoding of environmental DNA (eDNA) is a revolutionary technique for monitoring of ecosystems, but no single primer can amplify and discriminate all species in any environment. We developed MultiBarcodeTools, which automatically recommend the optimal combination of fish eDNA multi‐metabarcoding primers.
