Fig. 2
Changes in eye migration of Senegalese sole control larvae (a) and exposed to different malathion concentrations (b to d). Vertical bar show the percentage ± SD of fish at each stage of development. Different superscripts denote significant differences (P < 0.05) between control and malathion treatments at an age. Eye migration index (IEM) is shown as a line plot on each vertical bar chart. Asterisks shown significant differences (P < 0.001) between control and malathion treatments at the same age
