Aquatic Biology Associates, Inc. (ABA) is a woman owned small business (WBE) located in western Oregon. We are WBE certified in Oregon and for the California Public Utilities Commission. ABA is also an Oregon certified Tier-1 Emerging Small Business (ESB). Our taxonomists are certified by the North American Benthological Society (NABS). We are a member of the Southwest Association of Freshwater Invertebrate Taxonomists (SAFIT).

Our clients include federal agencies such as the U.S. Environmental Protection Agency, U.S.Geological Survey, National Oceanic and Atmospheric Administration, U.S. Department of Defense, U.S. Army Corps of Engineers, U.S. Fish & Wildlife Service, Bureau of Land Management, National Park Service, and the U.S. Forest Service. We also serve tribal communities, various state natural resource agencies, counties, cities, private industry, conservation and irrigation districts, citizen and nonprofit groups, universities, K-12 schools, and museums.

ABA is committed to sustainability and reducing negative impacts on the environment. Solar panels generate 92-103% of the electricity used in our office and laboratory facilities. We use recycled paper and plastic products, re-use shipping materials, sample containers and alcohol preservatives, and recycle office and lab waste.


I have been very pleased with the quality of work and customer service provided by Aquatic Biology Associates, Inc. My stream food-web studies have included benthic invertebrates, fish diets, and terrestrial invertebrate infall, and they have the expertise to handle all of types of samples. I have been very satisfied with the accuracy and timeliness of the data, and it has been extremely helpful to me to be able to talk directly to the person who has identified the samples (Robert Wisseman, Senior Scientist) when I have had questions or additional requests during the course of an ongoing project. Their high quality of work and customer support at reasonable prices provide an excellent value.

Aquatic Biology Associates has performed our taxonomic analysis for the City of Seattle for the past 16 years, and I have been very pleased with the high quality of both work and technical assistance. Bob Wisseman has always been willing to explain various aspects of the process, from the best way to preserve and ship the samples to the interpretation of the results. Our samples tend to be different from other area’s samples, since the sample sites are so highly urbanized, but that has never been a problem for this lab. I’ve always felt that ABA was willing to go the extra distance to make sure the City got the maximum value out of their biological sampling efforts.

Aquatic Biology Associates provided cost-effective and conscientious services tailored to our project objectives. Their high-quality data sets were presented in a way that could readily be understood by expert and non-expert reviewers alike. And Bob’s succinct interpretation of results related to water quality conditions being assessed for our project enabled us to determine likelihood of risk to the invertebrate community from project operations.
