  • Mousam River Too Hot For Native Fish

    | April 1, 2015

    The Wells Reserve conducted a study of water temperature in the Mousam River during the summer of 2013. What we found were conditions that do not support native coldwater fish species during the most critical time of the year.

    To learn more check out our report on what we found:

    2013 Mousam River Temperature Study

    Fish are generally confined to the water, for obvious reasons: they breathe through gills, don't have legs, prefer to eat aquatic insects, etc… (actually some did manage to get out, but it took millions of years). But that doesn't mean they don't move around. In fact fish do a great deal of moving around to locate food, escape being eaten, and find a suitable place to lay their eggs. For some species this involves traveling great distances and even moving back and forth between the ocean and rivers. Other species stay closer to home and spend their entire life in one environment or another. But for these "resident" fish it is still important to be able to move within their local stream networks to complete their life history.
