Dotted lines represent 95% confidence limits. grouping birth dates in 7-day intervals centered on the four phases of the moon. In 1989 peaks occurred around the full and first quarter moons (Fig. 6A), while peaks in 1990 centered around the full and third quarter moons (Fig. 6B). The greatest number of individuals were spawned in the seven days around the full moon in both 1989 and 1990, with lesser numbers around the first quarter in 1989, and the third quarter in 1990 (Fig. 7).
