Pulverised Neem and Mango Leaves Biosorption Effect on Hematology of Clarias gariepinus (African Catfish) Cultured in Lead-Contaminated Aquarium

Lead lethal and sub-lethal impact on aquaculture affect the environment, physiology and haematological indices in fish. The research investigated the biosorption effect of pulverized neem and mango leaves on lead-contaminated aquarium cultured with Clarias gariepinus. A total of 180 healthy juveniles of Clarias gariepinus were used for the period of the experiment. They were further divided into two groups of pulverized neem and mango leaves with ninety (90) in each. This was further divided into three groups of thirty (30) with each comprising the experimental groups of 15 mg/L and 10 mg/L of Pb and control. Biosorption was conducted on environment and blood parameters status was investigated. The results of pulverized neem and mango leaves showed no significant difference (p < 0.05) of biosorption in the environment and physicochemical properties while blood parameters showed significant differences (p < 0.05). For Pulverized Neem Leaf (PNL) and 10 mg/L had the higher statistical values in Haemoglobin count (HCT) 8.327%, White Blood Corpuscle (WBC) 64.160fL, Haemoglobin (Hb) 8.070fL, Platelet total (PLT) 326.000% while Pulverized Mango Leaf (PML) with 15 mg/L of lead appeared statistically significant in Mean Corpuscular Volume (MCV) 111.500fL and corpuscular haemoglobin count (MCHC) 94.000fL. The effect of PNL and PML on physicochemical properties and blood parameters was positive remediation in contaminated environment and physiological function in aquaculture.
