Aquatic Diagnostics Lab

Important Notice- We have moved to an online payment system for our most common tests including the base water chemistry test and water clearing treatment test. If you are unsure of the test(s) you are needing, please contact us before payment.

Please be aware due to dramatically increased demand and limited laboratory personnel, services offered by the Aquatic Diagnostic Laboratory have been reduced and the fee structure has been increased effective 4/14/2021. New test and price information can be found on the fees page by clicking on the “how much do lab tests cost?” button below.

Water clearing treatment test results take a minimum of 14 days from the day that sample is received. All other testing results take a minimum of 7 days from the day that sample is received.

The Texas AgriLife Extension Service Aquatic Diagnostics Laboratory (ADL) is housed in the Department of Wildlife & Fisheries at Texas A&M University. The laboratory was established in 2013 and provides water quality testing and fish parasite and disease diagnostics for aquaculture producers and private pond and lake owners.

The laboratory’s primary mission is to provide research based analysis and diagnostics and non-biased recommendations for owners of private waters and the stakeholders of Texas. The lab specializes in water chemistry to support fisheries and aquaculture, water clearing treatments, parasitology and bacterial histopathology.
