Environmental DNA for monitoring the impact of offshore wind farms on fish and invertebrate community structures

open access: yesEnvironmental DNA, Volume 6, Issue 4, July–August 2024.
Offshore windfarms are marine areas that are difficult to access, and innovative monitoring techniques are needed to study their impact on marine biodiversity. Water sampling and trawl catches conducted in parallel in 30 sites in the Belgian part of the North Sea showed that 12S eDNA metabarcoding retrieved 85.7% of the fish species caught in the beam ...

The Effect of Feeding with Chironomid and Artemia on Fatty Acids and Amino Acids Profiles in Persian Sturgeon (Acipenser persicus) Larvae

open access: yesAquaculture Nutrition, Volume 2024, Issue 1, 2024.
This study aimed to examine the effect of various live foods on the fatty acids (FAs) and amino acids (AAs) profiles in Persian sturgeon (Acipenser persicus) larvae. One thousand and two hundred larvae were cultured in circular concrete tanks, and four treatments were administered as: (1) Artemia + Daphnia, (2) Artemia, (3) Artemia + Chironomid, and (4)
