Dr. Woiwode, Fisheries Scientist and President of AquaMatrix International, Inc., has provided fisheries/aquaculture technical services and expertise worldwide. His active participation in and vision for international fisheries development began as a U.S. Peace Corps Volunteer in the Philippines, where he functioned as Hatchery Manager, producing Asiatic Carps and monosex tilapia fingerlings for regional distribution. His education includes B.Sc. Fisheries and Wildlife Resources and M.Sc. Fishery Resources degrees from the University of Idaho, and Ph.D. Fisheries degree from the University of Minnesota.

Dr. Woiwode has continually sought to complement his academic background with hands-on aquaculture/fisheries experience: He has designed, constructed, operated and trained the management for aquaculture systems that have ranged from extensive pond to intensive recirculating and geothermal systems, working with species as diverse as black tiger prawns to Pacific threadfin to Barbus cyprinids to tilapia and charr. He has an in-depth understanding of and hands-on working experience with all the necessary components, from hatchery and production operations to processing/HACCP requirements and product market entry, that ensure the success of aquaculture ventures under a wide variety of conditions.
