Exploring Prey Selectivity and Feeding Habits of Wels Catfish (Silurus glanis L., 1758) in a Deep Anatolian Reservoir: Seasonal, Length, and Age‐Dependent Diet Analysis

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
Feeding habits and dietary preferences of wels catfish (Silurus glanis) were investigated in Sıddıklı Dam Lake through the examination of 200 individuals. The results revealed that the species predominantly exhibited piscivorous feeding characteristics, with Tinca tinca (IRI% = 78.93) identified as the primary food source. The food items in the stomach

Distribution of Odorant Compounds in Recirculating Aquaculture Systems Used in Sturgeon Farming

Aquaculture Research, Volume 2025, Issue 1, 2025.
This study investigated the distribution of odorant compounds in water collected from the tank, drum filter, biological filter, and UV system outlets and the sludge inside the drum filter across two sturgeon RAS farms. A combinatory sensory‐analytical approach was applied to assess the aroma profiles via descriptive sensory analysis and the odorant ...

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

Environmental 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 ...
