The Study of Appropriate Strategy in order to Avoid Economiclosses Caused by the ICHthyophthirius Parasite on OrnamentalGoldfish Species

Introduction: This study aimed to provide the Appropriate Strategy in order to Avoid Economiclosses Caused by the ICHthyophthirius Parasite on Ornamental Goldfish Species in the city ofShiraz in the four cardinal directions .Methods: In this study Pearl scale, Calico, Black Moor, Red Cap and Lionhead species, wereexamined and the prevalence of parasites in different conditions such as different temperatures,different turbidity, algal growth, feeding rate and etc. were reviewed.Results: The main result is that management is the most important factor in this disease. The mostresistant and most sensitive species are Calico and Pearl scale, respectively. In the absence ofmanagement prevalence is associated with increasing temperature and reaches its peak at ۲۷ °temperature. The proper management reduces the disease at high temperatures. Increased waterturbidity, the amount of aeration, algal growth, water replacement rates are very important factorsthat make fish more susceptible to ICH disease.Conclusions: The results show that water temperature should be high for better and fastertreatment of the disease and fish parasites more quickly reach the stage tomite. Goldfish lives atlow temperatures, so it is better water temperature gradually raised from fish early life untilgoldfish reaches maturity to help fish adapt to high temperatures. This not only provides bettermanagement of ICH disease but also against other diseases and the disease can be treated quickly .
