26. WEAKNESSES OF AQUAPONIC PRODUCTION Lack of technical knowledge to produce product at a commercial scale. Lack of human resources to work with aquaponics systems. Lack of fishmeal for organic based feed. Mechanization of the planting and harvesting procedures have not been created and will be costly. Competing with the industrial growers on the mainland on a price point basis will be difficult. Delivering small quantities of one crop is inefficient. High start up costs for infrastructure will prohibit some farmers from entering aquaponics. Economic viability of this farming method is still questionable.

27. BENEFITS OF AQUAPONIC PRODUCTION · Uses 2% of the water that conventional farming requires · Zero use of petrochemical fertilizers and pesticides ·Demands healthy water chemistry for the fish which limits organic pesticides and other additives even further · Does not require agricultural land and may be built on various landscapes such as asphalt, rooftops, and in urban areas · Uses existing technologies, infrastructure, power and water of the site · Only energy input is electrical and may be supplied off the grid · The most environmentally sustainable method of farming available to current technology
