Aquaponics

Aquaponics is a sustainable food production system that combines traditional aquaculture (raising aquatic animals) with hydroponics (cultivating plants in water) in a symbiotic environment. In this system, the waste produced by aquatic animals provides nutrients for plants grown hydroponically, which in turn purify the water. It’s an efficient, environmentally friendly method of producing food, and cannabis can be grown using aquaponics, benefiting from the nutrient-rich water and contributing to the system’s sustainability.

Aquaponics System Components

• History of aquaponics, including ancient roots and modern development.
• Parts of an aquaponic system: aquaculture, hydroponics, effluent accumulation, and key components like biofilters and sumps.
• Live components in aquaponics: plants, fish, bacteria, and worms.
• Importance of plants and fish in aquaponic systems.
• Role of bacteria in nitrification for nutrient conversion.

Plant and Fish Selection in Aquaponics

• Various plants suitable for aquaponics, influenced by fish maturity and stocking density.
• Common fish species used in aquaponics and their role in nutrient provision.
• Different types of fish commonly raised in freshwater and saltwater aquaponics.
• Factors influencing plant nutrient availability and adaptation to aquaponic systems.
• Examples of suitable plants and fish for aquaponics.

Operational Aspects of Aquaponics Systems

• Main inputs required for aquaponics systems.
• Management of fish stocking, including spawn or fry addition and fish biomass ratios.
• Feed sources for fish in aquaponics.
• Nutrient requirements for plants in aquaponics.
• Water and energy usage in aquaponics systems.

Economic Viability and Research Challenges
