The John L. Fryer Aquatic Animal Health Laboratory (formerly Salmon Disease Laboratory) is a regional fish disease facility dedicated to the study of organisms infectious for salmonids and other species of freshwater fish.  The laboratory is named for Dr. John L. Fryer, who pioneered the fish disease research program at Oregon State University.  Research at the facility is conducted by investigators across campus on a variety of aquatic species. The AAHL was constructed through a grant from the Bonneville Power Administration and is supported by the Department of Microbiology, the College of Agricultural Sciences, and the College of Science.  The 9,000 square foot facility provides both wet and dry laboratories.

The John L. Fryer Papers include information about the building's namesake and some of the research that he pioneered. The Memorabilia Collection includes information about Fryer as well.
