Influence of the Physical Characteristics of Feed on the Digestive Processes of Atlantic Salmon, Salmo salar, Focusing on Gut Transit Time

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
Rearing variables, such as water temperature and dietary composition, can significantly affect gut transit time (GTT) in cultured Atlantic salmon (Salmo salar). These influences can accelerate the transit of digesta, leading to reduced nutrient digestibility and uptake, whilst impacting feed intake, appetite and gut evacuation, which collectively may ...

The Efficacy of Clove Seed Aqueous Extract as an Anesthetic Agent on the Stress Response of Mystus cavasius During Transportation

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
Mystus cavasius (locally known as Gulsha) is a commercially important catfish in Bangladesh, typically transported live in oxygenated polythene bags without anesthetics, often resulting in severe stress, injuries, and high mortality. This study evaluated the efficacy of clove seed aqueous extract (CAE) as a natural anesthetic at different ...

Covalent flavinylation is essential for efficient redox catalysis in vanillyl-alcohol oxidase [PDF]

open access: yes, 1999
By mutating the target residue of covalent flavinylation in vanillyl-alcohol oxidase, the functional role of the histidyl-FAD bond was studied. Three His(422) mutants (H422A, H422T, and H422C) were purified, which all contained tightly but noncovalently ...
