The effects of plant essential oils (Myrtus Communis L.) on growth performance, hematology and biochemical parameters of rainbow trout (Onchorhynchus mykiss)

The effects of plant essential oils (Myrtus Communis L.) on growth performance and safety of rainbow trout were studied. 60-day trial period and growth parameters obtained fish contained mass index specific growth rate, FCR and a status indicator in days (beginning, middle period, end of period) was measured. Blood tests at the end of the caudal vein was cut, and hematology parameters including total count globulin red, white, hemoglobin, hematocrit, mean corpuscular volume (MCV), cell hemoglobin concentration (MCHC), the cell hemoglobin (MCH) , total protein, albumin, globulin, glucose, cholesterol, Triglyceride measured. The results showed that plant essential oils in three significant effects on growth parameters were rainbow trout. But the results show significant differences between treatments hematological parameters among all parameters with the exception of blood hemoglobin, cell hemoglobin concentration (MCHC) and cell hemoglobin (MCH) was observed. In general it can be concluded that plant essential oils to improve the safety performance salmon in the fish farming ponds and the best result was 3 kg.
