Ornamental freshwater fishes are widely maintained in aquaria, ornamental fish shops, breeding facilities, and culture systems. Deterioration of water quality can impose physiological stress on fish and may increase susceptibility to parasitic infection. The present study evaluated the relationship between selected physicochemical water quality parameters and parasitic infections in ornamental freshwater fishes from the Latur region of Maharashtra, India. A total of 240 fish specimens representing six ornamental freshwater fish species were examined. Water temperature, pH, dissolved oxygen, ammonia, nitrite, nitrate, electrical conductivity, total dissolved solids, and total hardness were assessed. Fish were examined for external and internal parasites using standard parasitological procedures. The overall parasitic prevalence was 54.17%. Koi showed the highest prevalence (73.33%), while Gourami showed the lowest (40.00%). Ammonia and nitrite showed strong positive associations with parasite prevalence and intensity, whereas dissolved oxygen showed strong negative associations. Parasite prevalence was substantially higher in the deteriorated-water-quality group than in the better-quality group. The findings indicate an important association between water quality deterioration and parasitic burden in ornamental freshwater fishes.
KEYWORDS
The findings indicate a clear association between deteriorated water quality and increased parasitic infection in the examined ornamental freshwater fishes from the Latur region. Elevated ammonia and nitrite, increased nitrate, conductivity and TDS, together with reduced dissolved oxygen, were associated with greater parasite prevalence and intensity. Maintaining suitable water quality, adequate filtration, appropriate stocking density, proper feeding, quarantine of new fish, and routine parasitological surveillance should form the basis of effective ornamental fish health management.
