L-arginine, matters for skin health of leopard coral grouper (Plectropomus leopardus)

, 2023
Abstract An 8 weeks feeding trial was conducted in leopard coral grouper to observe the effects of dietary arginine (Arg) level on growth and skin health about development, pigmentation, antioxidant ability, immune capacity. Fish were feed five iso-lipidic and iso-proteic diets containing the Arg 2.4%, 2.9%, 3.4%, 3.9%, 4.4%, respectively ...

Patterns in the chaos: Scale and the spatiotemporal dynamics of coral reef fish assemblages on the Great Barrier Reef

Ecosphere, Volume 16, Issue 5, May 2025.
Abstract In the Anthropocene, understanding and managing ecological communities requires the characterization of natural spatiotemporal ecosystem dynamics. Complex ecosystems may appear chaotic and unstructured, making long‐term monitoring programs with hierarchical sampling designs ideal for investigating ecological patterns at multiple scales.

What acoustic telemetry can and cannot tell us about fish biology

Journal of Fish Biology, Volume 106, Issue 5, Page 1260-1284, May 2025.
Abstract Acoustic telemetry (AT) has become ubiquitous in aquatic monitoring and fish biology, conservation, and management. Since the early use of active ultrasonic tracking that required researchers to follow at a distance their species of interest, the field has diversified considerably, with exciting advances in both hydrophone and transmitter ...
