| Purpose: Rainbow trout (Oncorhynchus mykiss) has played an important role in animal protein supply in recent years. However, parasitic infestation is one of the main concerns threatening their health. Parasites cause many complications, including reducing growth rate, feed efficiency in fish. They can also afflict skin, urinary, and digestive systems. In order to implement strategic plans for prevention and control of this disease, monitoring the frequency of contamination can provide useful information to farm clinicians. Method: In this study, the parasitic contamination of 61 pieces of rainbow trout from farms in Fars province in the spring of 1402 was evaluated. For this purpose, fish with symptoms such as anorexia, lethargy, skin spots and jumping were collected. After referring to the laboratory, sampling was done from different organs and the results were analyzed. Results: Out of a total of 61 fish examined, 13 pieces (21%) were infested with parasites. Of these, 11 fish (18% of the total population) were infested with Ichthyophthirius multifiliis parasite and two cases (3% of the total population) were infested with Trichodina sp. All the infected fish of the current study had common clinical symptoms of anorexia and lethargy. In the current study, the most observed parasite was Ichthyophthirius multifiliis, which constituted 84% of the patient’s population. Conclusions: According to the results, it can be deduced that a significant number of the cases (79%) with skin symptoms or lack of appetite were free of parasitic infestation and probably suffered from other types of infectious diseases. |
