Description:
The effect of exposing juveniles of Heterobranchus bidorsalis (Geoffroy St. Hilaire, 809) (mean weight: 15.02~c:0.14g) to different concentrations of Bonny-light crude oil (BLCO) on alanine kinase and alanine transaminase activities were studied. The exposure of the fish to 1.00, 2.00, 4.00, 8.001L-1 BLCO and a control (0.00m1 L-1) within 4 days toxicity and 42 days recovery periods indicated that the significant increases (P〈0.05; P〈0.01) in the serum alanine transaminase (HCAT) activities were dependent on the BLCO concentrations. The reduced SAK and (HCAK) activities noticed within the first 14 days recovery period implied that the removal of the oil pollutant probably lowered the pressure on the SAK and HCAK to participate in the metabolism of ingested carbohydrate. The significant increases in the serum alanine transminase (SAT) and the hepatic cytosolic alanine transminase (HCAT) activities in the fish corresponded with the trend shown by the SAK and HCAK activities. Generally, the increased activities of SAK, HCAK, SAT and HCAT in H. bodorsalis juveniles in this study might be due to a shift in the carbohydrate metabolism of the fish caused probably by the crude oil exposure.
