Exploring Prey Selectivity and Feeding Habits of Wels Catfish (<i>Silurus glanis</i> L., 1758) in a Deep Anatolian Reservoir: Seasonal, Length, and Age-Dependent Diet Analysis. [PDF]
Aquac NutrFeeding 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

Optimal Tryptophan Improved Growth and Regulated Agonistic Behavior of Oriental River Prawn, <i>Macrobrachium nipponense</i>. [PDF]
Aquac NutrTryptophan, recognized as the third limiting amino acid, plays a crucial physiological function. The optimal tryptophan requirement for oriental river prawn (Macrobrachium nipponense) was assessed, and its impact on agonistic behavior was evaluated in this study. An 8‐week feeding trial was implemented with six different tryptophan levels: 0.07%, 0.17%,
