Summary

Response of Rio Grande silvery minnow from three year classes and four age groups to one of seven temperatures (nominally; 28.5, 30.0, 31.5, 33.0, 34.5, 36.0, and 37.5ºC) and a control (25ºC) for 96 hours under static conditions.

Purpose

The endangered Rio Grande silvery minnow (Hybognathus amarus) was historically one of the most abundant and widespread fishes in the Rio Grande basin, but currently occupies only about five percent of its historic range. The decline of the Rio Grande silvery minnow has been attributed to several factors including water diversions, stream channelization, competition with and predation by nonnative fishes, and degraded water quality conditions in the Rio Grande. As a result of water diversions in the Middle Rio Grande, extensive portions of the river channel in the Isleta and San Acacia Reaches become intermittent or dry during the summer and autumn. During such periods, silvery minnows must seek out isolated pools or any other remaining aquatic habitats. Although few data are available on water quality conditions in these isolated pools, it is reasonable to expect that these habitats may experience elevated temperatures and depressed oxygen concentrations. The objective of this laboratory research was to evaluate intraspecific variation in thermal tolerance through determination of the upper lethal and effect levels of temperature to four life stages/age groups of silvery minnows from three year classes.
