Summary

Elevated levels of ultraviolet-B (UV-B) radiation resulting from stratospheric ozone depletion may cause harmful effects in freshwater fishes. We investigated the effects of simulated solar UV-B radiation on rainbow trout (Oncorhynchus mykiss) and two threatened salmonids, Apache trout (Oncorhynchus apache) and Lahontan cutthroat trout (Oncorhynchus clarki henshawi). Lahontan cutthroat trout and Apache trout are threatened because of habitat loss and competition from non-native fishes. These species inhabit clear-water alpine habitats and may be at risk from elevated levels of UV-B radiation. In the laboratory, fish received daily 5-h exposures to UV-B radiation during a 16-h photoperiod. A solar simulator generated a total UV-B (290 [...]
