We are primarily an aquaculture design - construction - management company. AquaMatrix's aquaculture facility designs are guided by two philosophical principles:

1) System designs should prioritize optimum fish health.

Optimum health yields maximum growth. All AquaMatrix designs and water, health and stock management practices embrace this perspective. Preventative Health Management is the guiding theme.

2) System designs should be management and production oriented.

Thirty years of hands on experience guide the operational designs and management of AquaMatrix facilities.

Refinements of intensive/recirculating aquaculture technologies have been a focus of AquaMatrix. Dr. Woiwode's experience with this technology dates to 1978, when he developed and successfully operated two recirculation systems for the geothermal applications program of the U.S. Department of Energy. He has continued to develop operational recirculation systems, worldwide.

Serving as Chair of the "Role of Aquaculture in World Fisheries" session at the first World Fisheries Congress in Athens, Greece, Dr. Woiwode summarized the state of recirculating systems in a paper entitled "Recent Advances in Predictive Recirculating Aquaculture Technology".

The most recent recirculating system activities have been the design and construction of the state-of-the-art hatchery and grow out tilapia and trout facility at Sheridan College, Wyoming. The AquaMatrix team currently manages that facility in a joint venture with the College.


Sheridan College fish nursery and production units. The facility has capabilities for single pass open, hybrid water flow or closed, recirculating management protocols, for cold or warm water species.

AquaMatrix has actively worked in the prawn/shrimp industry since 1988. We have contractually managed semi- and intensive production of black tiger prawns in the Philippines, employing skilled fisheries management to achieve sustainable prawn production.

Dr. Woiwode has directed two black tiger prawn projects in the Philippines funded by USAID. The first developed health management guidelines for prawn production in Negros; the second provided detailed nationwide analyses of the Philippine Prawn Industry at the Presidential level, and prescribed workable solutions for the bottlenecks of all facets of the industry, from hatchery production to feed milling to environmental interactions.
