Means with the same superscript lower-case letter in the same column, and means with the same superscript capital letter in the same row, for each parameter are not significantly different. Student t test was performed between two fish species for each parameter in each site (P t), whereas F test was performed between three locations for each biochemical parameter and each fish species (P F)
