Quantification of endogenous marker acid‐insoluble ash in commercial aquaculture ingredients and feeds

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract This study investigates the efficacy of acid‐insoluble ash (AIA) as an endogenous digestibility marker in commercial aquaculture ingredients and feeds. AIA is a naturally occurring, low‐cost alternative to external markers such as chromic oxide and yttrium oxide. External markers are often impractical in the production of small batches of feed

Dietary selenium nanoparticles (SeNPs) mediate intestinal microbiome and microbiota‐derived metabolites regulating the growth and immunity of Nile tilapia

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract Maintaining a healthy intestine is essential for growth and host defense mechanisms of farmed fish, particularly those densely stocked. In this context, maintaining a healthy intestinal microbiota for proper digestion, absorption, and integrity of the mucosa is of utmost importance.

Corn‐fermented protein as a replacement for fish meal in diets for Atlantic salmon, Salmo salar, parr: Growth, feed utilization, antioxidant activity, non‐specific immune response, and gut histopathology

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract Fishmeal (FM) is still believed to be the gold standard protein source, especially for high‐value aquaculture species such as salmon. However, due to supply and price fluctuations, coupled with environmental issues in FM production, FM is no longer a sustainable source from economic and environmental perspectives.

Oxygen chemoreceptor inhibition by dopamine D2 receptors in isolated zebrafish gills

open access: yesThe Journal of Physiology, Volume 603, Issue 8, Page 2369-2385, 15 April 2025.
Abstract figure legend Transgenic Tg(elavl3:GCaMP6s) zebrafish, which express an endogenous calcium reporter in gill oxygen chemoreceptors and nerve terminals, were used to explore the role of dopamine in hypoxia signalling. We discovered that dopamine via presynaptic dopamine D2 receptors (D2R) provides a feedback mechanism attenuating the ...
