I specialize in zero water exchange aquaculture systems which are disease free and have a positive impact on the environment. I have lived and worked in 5 countries, written many business plans, consulted to many industries and designed and managed aquaculture production systems that set world records in biomass per unit volume (shrimp biomass 9.75 kg/m3 at 26.6 g average size and 5.2 kg/m3 at 67 g). More recently, research into mercury toxicity, documenting the coral bleaching in every reef system in Panama and the first in the world to grow the Pacific spiny lobster, Panuliris gracilis,  in a zero water exchange system in Boquete, Panama at 5 kg/m3 (see Aquaculture and Corals- Recent Articles Published)
