ABSTRACT:

Oreochromis niloticus (tilapia) and Chrysichthys nigrodigitatus (Catfish) sampled from Alakiri river in Rivers State, Nigeria, were examined for some biochemical indices andblood serum enzymes activities to assess the effects of environmental stress on fish health. The results were compared with those of Oinuhuechi river (baseline) in RiversSta_te, Nigeria. The activity of Aspartate -aminotransferase (AST), Alanine­aminotransferase (ALT) and Alkaline phosphatase (ALP) in Alakiri fish samples varied significantly (P:;0.05) from those obtained from the base-line zone. Although, Albumin,fotal Cholesterol and High Density Lipoprotein (HDL) Cholesterol levels in O. niloticus did not differ significantly, total protein and glucose levels showed marked variations in samples drom the two rivers. Such variation were also evident in the levels of total protein, glucose, albumin and HDL. Cholesterol in C. nigrodigitatus. The high of levels total of the biochemical indices in fishes (tilapia and catfish) collected from Alakiri rivers suggests that constant discharge of industrial effluents into the aquatic environment has an adverse effect on the health of aquatic fauna.
