| dc.description.abstract | Pollution of aquatic environment is a serious and growing problem. Increasing number and amount of industrial, Agricultural and commercial chemical discharged into the aquatic environment led to various deleterious effects on the aquatic organisms. The hepatic enzyme of black jaw tilapia, Sarotherodon melanotheron collected from the Lagos Lagoon were evaluated in relation to water quality parameters for a period of 3 months (July-August 2012). The physico-chemical parameters of water samples were monitored at both high and low tides. Serum from blood samples of S.melanotheron were analyzed for alkaline phosphatase (ALP), alanine tranaminase (ALT), and aspartate transaminase (AST). MeanSD ALT values were 6.112.21, 17.004.33 and 25.674.45, AST values were 19.934.69, 71.9422.87 and 98.2917.00 while ALP vales were 23.4615.46, 45.549.76, and 66.7916.80 for July, August and September respectively. Analysis of variance (ANOVA) showed no significant difference (P>0.05) in enzyme level within the three months of study. AST showed strong positive correlation with ALT (r=0.795) and a weak positive correlation with ALP (r=0.53) and ALP showed weak positive correlation with ALT (r=0.51). The physico-chemical parameters of water were optimal at both high and low tides. There was a weak positive correlation between the condition factor and length (r=0.32), as well as condition factor against weight (r=0.218) and the correlation of length against weight showed a positive correlation (r=0.928). In this study, the results suggest that environmental stress was noticed in the Lagos Lagoon indicating the increasing level of biochemical stressors at varying levels which had sub-lethal effects on the health of the fishes. | en_US |
