Author(s): Wachap RI, Annune PA and Solomon SG
Abstract: This research was done to find out the sub lethal effects of detergent kiln
® on
Oreoc
hromis nilotic
us juveniles due to the contamination of fresh waters with a wide range of pollutants. The Nile Tilapia,
Oreochromis niloticus was exposed to linear alkyl benzene sulphonate (kiln
(R)) for 56 days after obtaining the LC
50-96 which was 22.26mg/l. Fractions of 11, 1.5 and 1.9mg/l for
Oreoc
hromis nilotic
us representing 1/20, 1/15 and 1/12 respectively of these LC
50 values were used for the 56day chronic exposure study following a static renewal protocol so as to monitor its effects on the fish’s haematology. Blood were collected after 56 days by randomly selecting fish from the various treatments and inserting a 2mm needle and syringe through the dorsal aorta puncture and placed in ethylene-diamine-tetra-acetic-acid (EDTA) treated bottles to prevent coagulation. The hematological parameters estimated include haemoglobin, mean cell haemoglobin, mean cell haemoglobin concentration, packed cell volume, mean cell volume, Red blood cell count sand white and red blood cell counts. Results showed that the PCV, WBC, RBC, MCH, MCHC, and Hb were significantly different and decreases with increasing concentration ofklin.
