Abstract
As human population increases with the growth of industrialization, there is a resultant increase in the rate of pollution in aquatic ecosystems. Changes in plasma concentrations can be indicative of stress in fishes exposed to pollutants. This study investigated the toxicity and plasma indices changes in Chrysichthys nigrodigitatus of Bariga landing site, Lagos lagoon. Physiochemical parameter of Bariga landing site (Lagos lagoon) were also analyzed. Temperature, pH, dissolved oxygen, salinity, transparency had a mean of 25±1.0, 7.44±0.05, 4.33±0.15, 15.33±3.06, 73.17±0.76 respectively. TSS, phosphate, COD, BOD, nitrate, TDS had a mean value of 2.0±0.58, 2.0±0.58, 13.1±1.015, 8.87±0.23, 5.3±0.1, 161.13±9.50 respectively. The mean value of AST, ALT, ALP, CHOL, GLU, TP enzymes activity in the plasma of Chrysichthys nigrodigitatus from the month of May to July are 48.26±77.54, 21.79±13.49, 62.10±44.198, 86.21±27.64, 51.18±10.78, 24.58±14.10 respectively. The AST, ALT, ALP found within the cells of the liver, kidney, gills were high in the plasma of Chrysichthys nigrodigitatus which may be due to tissue injury or organ dysfunction caused by stress. The reduction in cholesterol, glucose and total protein concentration was due to exposure to stress by pollutant. The Biochemical profile of fish proves to be a sensitive index for the evaluation of fish metabolism under oxidative stress from the lagoon. However, the biochemical parameters of blood plasma in this study showing its usefulness as a tool in monitoring the physiological status of fish and as an indicator of the aquatic environmental health.
