Briefings

Researchers from the University of Liège discovered that European eels can transmit a herpesvirus via bites during aggressive interactions, contradicting the long-held belief that water is the only vector for fish infections. This finding expands the known routes of viral transmission in fish populations.

Key points

• Viruses infecting fish are not transmitted exclusively through water acting as an abiotic vector.
• A virus affecting European eels spreads efficiently through biting during aggressive interactions between individuals.

Context

This discovery challenges existing assumptions about fish disease transmission, potentially impacting conservation efforts and disease management strategies for eel populations.

Limitations

Evidence is limited to a single study from the University of Liège; no broader epidemiological data or long-term impact assessments are provided.
