With great sadness, we announce the passing of Dr. Donald V. Lightner.


We are sad to share that Dr. Donald V. Lightner passed away on May 5, 2021 in Tucson, Arizona.  He will be missed by his family and friends, and by academic and industry colleagues around the world. The world of aquaculture—especially aquatic animal disease specialists—has lost an icon.

In the 1970’s, Dr. Lightner put together a team of researchers at The University of Arizona that provided much of the basic knowledge on shrimp disease and health which enabled shrimp aquaculture grow into a global industry that now supplies more than half of all the shrimp consumed around the world. 

Virtually every shrimp disease expert in the world has had some connection with Dr. Lightner and the Aquaculture Pathology Laboratory in The University of Arizona. Don’s contributions were both applied on his visits to farms around the world, and academic with hundreds of scientific articles, industry reports, conference presentations, graduate students, and short courses. 

APL's roles as the World Organization for Animal Health (OIE, Paris, France) Reference Lab for crustacean health and as a major service provider for industry are testimony to Dr. Lightner's worldwide reputation as the go-to expert for shrimp health. We here at APL are and will continue to be grateful for the opportunity to carry on his legacy.

Testing Available for DIV1/SHIV!
