Dietary Supplement of Tumeric (Curcuma longa) Powder: Impact on Haematological and Biochemical Responses in Clarias gariepinus (Burchell, 1822) Fingerlings

Abstract

Dietary supplementation with herbal extract in the diet of fish has been noted to increase aquaculture production through the improvement of immunity and other physiological dysfunctions related to fish health. A feeding trial was conducted to assess the impact of incorporating varied concentrations of turmeric powder (TP) on haematological and biochemical responses in Clarias gariepinus fingerlings. Five test diets were composed as T1 ((control) (basal diet + 0 % TP)), T2 (basal diet + 1 % TP), T3 (basal diet + 2 % TP), T4 (basal diet + 3 % TP) and T5 (basal diet + 4 % TP). Fish specimens were apportioned into five groups in triplicate. Significantly lower (P
