In the evaluation of the effect of acidic water on the symmetrical development of the pelvic spines in juvenile three‐spined sticklebacks Gasterosteus aculeatus , directional rather than fluctuating asymmetry was found, with left spines being, on average, longer than the right. Fish that were exposed for a period of c. 2 months to acidic pH levels grew significantly more asymmetrical pelvic spines than their control full‐siblings held in unmanipulated water. Average spine size was not affected by the experimental treatment.
