FIG. 1.
Increase in total live embryo count from two AB wild-type populations of fish housed in front of a red versus green emitting EXIT sign compared to the control group. Under Red light, the average over a 10-week trial represents a statistically significant difference and a 56% increase in embryos spawned. Under Green light, no significant differences in embryos spawned were observed over a 10-week trial. Color images available online at www.liebertpub.com/zeb
