Mark Francis, President
Pioneering Solutions at Aquaneering
Aquaneering has grown from a part-time aquaculture supply business to the internationally recognized leader in the manufacture and engineering of fluidized bed biofiltration systems for aquatic housing and aquaculture. Mark Francis, president and owner of Aquaneering Inc., received his B.S. in agricultural engineering from the University of Maine in 1978. He then moved to California where he worked as a manager for a commercial fish farm. Here, Mark began designing and building equipment for the farm, everything from paddlewheel aerators to feeders.

In 1988 Mark began working with Dr. Dallas Weaver, and started manufacturing his fluidized bed biofilters for recirculating systems. This revolutionary new filter system is able to maintain superior water quality with undetectable levels of ammonia, a major technological advance for the aquaculture industry.

While working as chief engineering for a manufacturing plant in San Diego, Mark founded a fish farm equipment supply business, and appropriately named it Aquaneering. The company focus shifted with the industry, and the emphasis changed from large farm equipment to recirculating systems.

Aquaneering now has an international client base with successful installations throughout the United States and the world. Since 1996, fluidized bed biofilter systems have been proven to be superior biological filtration for applications requiring the highest water quality, such as zebrafish genetics research.

Aquaneering is committed to providing the biomedical research community with the highest quality equipment, consulting, installation, and service.
