Updates on Selected Emerging Infectious Diseases of Ornamental Fish.

Area of Science:

• Aquatic Animal Health
• Veterinary Virology
• Fish Pathology

Background:

• Ornamental fish populations are increasingly threatened by emerging infectious diseases.
• Several specific pathogens, including goldfish herpesvirus and koi herpesvirus, pose significant risks.
• Many emerging fish diseases exhibit broad host ranges, affecting various species globally.

Purpose of the Study:

• To review emerging infectious diseases in ornamental fish.
• To highlight clinical relevance, detection methods, and potential treatments.
• To emphasize the importance of preventative measures.

Main Methods:

• Literature review of emerging infectious diseases in ornamental fish.
• Focus on clinical signs, etiological agents, and diagnostic approaches.
• Discussion of management and biosecurity strategies.

Main Results:

• Identified key emerging diseases: goldfish herpesvirus, koi herpesvirus, carp edema virus, Erysipelothrix, Edwardsiella ictaluri, Edwardsiella piscicida, and Francisella.
• Noted that some diseases are species-specific, while others affect a wide range of fish.
• Highlighted the global impact of these diseases on ornamental fish.

Conclusions:

• Effective management of ornamental fish requires understanding emerging diseases.
• Biosecurity, proper husbandry, and disease surveillance are essential for prevention.
• Proactive disease detection plans are vital for ornamental fish health.
