The summary of the effects of elevated temperature and stress on the reproductive function in rainbow trout is very well done. The assumption that these stressors may have similar effects on the growth and reproductive capacity in bull trout may have merit, but first the proponents need to convince us that bull trout are having a significant problem with growth and reproductive capacity in the wild. Problems with reproduction in bull trout are currently not known to exist. We are convinced that this laboratory study will produce quality data and results, but how will those data be applied?

This proposal will remain at a low priority for funding until elevated temperature or total dissolved gas effects on growth or reproductive capacity of bull trout are identified as potentially significant problems.
