  • Growing plants in a water/nutrient solution without soil
    • Takes less:
      • Labor
      • Time
      • Space
      • Fertilizer
aquaculture
aquaculture
  • A form of agriculture that involves the propagation, cultivation and marketing of aquatic plants and animals.
    • Types of systems:
      • Intensive recirulating
      • Pond culture
      • Cage culture
      • Raceway culture
aquaponics
Aquaponics
  • The combination of hydroponics and aquaculture in a recirculating system.
      • Fish waste
        • Ammonia-nitrite-nitrate
      • Beneficial bacteria
      • Is it worth it?
symbiotic relationships
Symbiotic Relationships
  • A close ecological relationship between 2 or more different species.
    • Types of relationships:
      • Mutualism
      • Commensalism
      • Parasitism

what are some examples?

compatible species
Compatible species
