Alterations in the blood parameters of Clarias gariepinus (Clarridae) feed varying inclusion of levels of rubber seed meal (Havea brasiliensis)

Abstract

Haematological changes in Clarias gariepinus juveniles fed diets containing Rubber (Havea brasiliensis) Seed Meal (RSM) at varying inclusion levels (0%, 5%, 10%, 15%, 20%) was evaluated in a ninety-day feeding trials. Four iso nitrogenous and iso caloric diets containing the fish feed diet showed significant (P<0.05) difference over fish feed control diet with respect to WBC, Hb, MCH mean corpuscular haemoglobin concentration (MCHC). Fish feed control diet had the lowest WBC, Hb, MCH, and MCHC. There was no significant difference (P >0.05) in the fish fed control diet and test diets with respect to RBC. Hence it can be concluded that the haematological parameters of Clarias gariepinus is not significantly (P>0.05) changed with increase dietary inclusion of rubber seed meal.
