Fig. 2. Color preference test for visual recognition in 11 dpf zebrafish after embryonic HgCl₂ exposure. (A) Video tracking of free–swimming zebrafish for 30 min. A single zebrafish (indicated by an arrow) was positioned individually in the center of a cross maze equipped with four different colored sleeves. AnimalTracker in ImageJ software was used for analysis. Color preference itself was not significantly changed (B), but exploratory activity (distance travelled) was reduced in HgCl₂–exposed zebrafish (C) compared with controls (most preferred: blue > red > green > yellow). However, green and yellow were the least preferred in HgCl₂–exposed zebrafish. An NMDA receptor antagonist MK− 801 displayed no color preference and significantly reduced exploratory activity (mean ± SEM: *p < 0.005, n = 30 for each group).
