The health status of the zebra-snout seahorse, Hippocampus barbouri in captivity has been required for approval aquaculture. In this study, we investigated histopathological appearance three vital organs including gill, kidney and liver captive H. during its juvenile adult stages, by using histological techniques. juveniles from stage 14-days (100% prevalence) towards 30-days adults prevalence), gills exhibited intraepithelial edema necrosis while hepatic tissue showed evidence intracytoplasmic vacuoles. addition, alteration to renal tissues was observed degeneration tubules, presence melanomacrophage, infection trematode parasites. parasites were found fish (33.3 % prevalence). Taken together, study highlights issue rearing barbouri, particular alterations tissues, suggesting that aquaculture seahorse species requires improved methods protocols maintenance preventing infection.
