Fisheries & Aquatic Sciences

We specialize in providing environmental documentation of aquatic resources to organizations who are either working to develop resources or are working to manage or restore aquatic habitats, water quality, and fisheries resources. Our expertise includes the taxonomy, distribution, and ecology of North American fish species, as well as surveying freshwater lakes, streams, large rivers, and nearshore marine environments throughout Alaska.
