Cause and Effect
There are dramatic cause and effect relationships between human actions
in watersheds and changes to fish habitat — and ultimately — fish populations.
Cramer Fish Sciences has pioneered the development of analytical
tools to predict these effects.
Several of our scientists have dual training in watersheds and fish biology.
They study and analyze the relationships between watershed processes, fish
habitat, and fish populations. This expertise gives our clients the unique
ability to estimate the results of changes to the watersheds they manage.
