This fastidious mycobacterium can cause systemic disease in laboratory zebrafish and persist in biofilms, calling for integrated fish and environmental surveillance.
In Port Jackson sharks, suturing internal-tag incisions reduced protrusion risk but increased inflammation and bacterial colonisation, revealing a protocol trade-off rather than a universal rule.
A study across eight Italian farms documents AcIV-E circulation and the diagnostic challenge posed by non-specific signs and the lack of routine cell culture.
FELASA–AALAS recommendations provide a structured way to introduce fish colonies while protecting health status, staff safety and the reliability of research.
Standardised reflex observations can provide a rapid field measure of fish vitality after capture, provided the protocol is validated for the species and release context.
An experimental killed bacterial vaccine delivered in feed improved channel catfish survival after Aeromonas challenge, highlighting both the promise and constraints of oral boosters.
Research at the Tennessee Aquarium shows how flow, depth and substrate shape fish space use, turning microhabitat choice into evidence-based enrichment.
A US field study combines PFAS measurements in wild fish with tissue pathology and molecular responses, offering a practical model for integrated aquatic surveillance.
