Abstract

This study deals with evaluation of the hematological effect of natural medicinal plants, Allium sativum and Thymus vulgaris on parasites of African Catfish, Clarias gariepinus as an effective solution for improving fish aquaculture and fish health. A total of 200 specimens, Clarias gariepinus were divided into four groups, control (G1), 0.1 g/L of garlic water extract (G2), 0.1 g/L of thyme water extract thyme (G3) and 0.05 g/L of garlic water extract mixed with 0.05 g/L of thyme water extract (G4) groups. Each fish group was placed in 250 liters of water from River Nile for 4 weeks. Results concluded that beneficial supplementation of T. vulgaris improves growth rate of common catfish and improved blood parameters (eg, hemoglobin count, RBC count, WBC count). The present results displayed positive effects of garlic and thyme supplemented on healthy status as natural source for fish aquaculture.
