Table 1. Hair cell numbers do not return to normal levels following cessation of ethanol treatment.

	O2 neuromast		Mi1 neuromast

Control	13.1±2.3	12.4±0.9	12.8±1.8	11.1±0.92
1.00% EtOH	10.2±2.0	9.4±1.6	10.6±2.0	9.1±1.0

Zebrafish were treated with ethanol from 2 days post-fertilization (dpf) to 5 dpf. Some animals were fixed and hair cell counts from the O2 and Mi1 neuromasts were obtained. Other embryos were raised in embryonic medium from 5 dpf to 10 dpf, fixed, and then hair cell counts were obtained. There were no significant differences in the number of hair cells within a specific condition between 5 dpf and 10 dpf larvae (p>0.1). Results are mean ± SD (n = 10-15 per condition).
