A total of 18 live specimens of the black jaw tilapia,
Sarotherodon melanotheron, mean
weight (82.95 ±3.27g)
and mean length (13.1 ±0.35cm), were sampled bimonthly for three months from the Makoko
area, a slum neighbourhood, of Lagos Lagoon, to establish the haematological
and biochemical indices of the fish species which will serve as baseline for
further studies and ascertain the health of the environment. The mean value and
standard error of mean of some of the haematological parameters analyzed were: Hb: 89.65 ±3.63g/l, PCV: 27.47 ±0.58%, RBC: 3.05 ±0.06T/L,
WBC: 10.02 ±0.40g/L, MCV: 86.87 ±1.39fl, MCH: 29.64±0.62pg, MCHC: 33.29
±0.13g/dl, Neutrophils: 22.89 ±0.63%, Lymphocyte: 79.67 ±1.49% and Monocyte:
0.72 ±0.25%. No Eosinophils and Basophils were recorded in this study. While
the mean and standard error of mean of the biochemical enzymes analyzed in
IU/L, were: AST (76.84 ±4.08), ALT (23.06 ±2.12) and ALP (77.74 ±6.12). There
was statistical significance (p<0.05) in the following haematological
parameters: Hb, WBC, MCV, Neutrophils and Lymphocytes. There was statistical
significance (p<0.05) in all the biochemical indices. It was established
that the water was polluted with heavy metals, sewage and other organic pollutants
such as wood wastes, and that these pollutants have altered the haematology and
biochemistry of the fish species.
