Expertise

My Research Interests:

  • aquaculture
  • reuse of effluents for crop irrigation
  • aquaponics
  • tilapia
  • shrimp
  • seaweeds and multi-trophic systems
  • sustainable feeds
  • international economic development

Skills and Expertise:

  • Irrigation
  • Nitrogen
  • Water Quality
  • Fertilizers
  • Soil
  • Marine Ecology
  • Aquaculture
  • Waste
  • Wastewater
  • Sustainability

My research is directed primarily toward production techniques of tilapia and shrimp in the desert and in integrated systems. Multiple use of water for aquaculture and irrigated agriculture has been a focal point. A second broad area of resesarch is control of aquatic nuisance species.
