Pathologic findings in weedy (Phyllopteryx taeniolatus) and leafy (Phycodurus eques) seadragons

Area of Science:

• Marine Biology
• Aquatic Animal Health
• Veterinary Pathology

Background:

• Weedy (Phyllopteryx taeniolatus) and leafy (Phycodurus eques) seadragons are unique marine fish species often housed in aquariums.
• Understanding diseases affecting these populations is crucial for conservation and husbandry.
• Previous research has not comprehensively detailed the pathological findings in these specific seadragon species.

Purpose of the Study:

• To retrospectively analyze pathologic findings in aquarium-held weedy and leafy seadragons.
• To identify the range and occurrence of diseases affecting these populations.
• To highlight species-specific disease patterns for improved veterinary care.

Main Methods:

• Retrospective analysis of pathologic diagnoses from 1994 to 2012.
• Inclusion of specimens from two reference laboratories.
• Categorization and comparison of diagnoses between weedy and leafy seadragons.

Main Results:

• Mycobacteriosis and scuticociliatosis were common diagnoses in both species.
• Myxozoanosis was prevalent in weedy seadragons, often co-occurring with other diseases.
• Intestinal coccidiosis affected weedy seadragons, while swim bladder mineralization was more common in leafy seadragons.

Conclusions:

• Weedy and leafy seadragons share significant diseases, necessitating awareness for aquarium management.
• Distinct pathological conditions exist for each species, requiring tailored diagnostic and treatment approaches.
• This study provides valuable data for veterinary pathologists and clinicians managing seadragon populations.
