|Abstract:||The effective use of land for maximal food production is a forever-increasing worry to islands in the Pacific, which have experienced rapid population growth. To address this we examine linked fish and vegetable production using a recirculating water system. This system is designed to achieve a high degree of efficiency of water use for food production without soil. Twenty-four identical systems were used, in which each system contained a biomass of 1.5-kg tilapia species (Oreochromis spp.) grown in 400-L freshwater tanks associated with two ebb-and-flow 25-L bio-filters (cinder rocks). Capsicum frutescens (Hawaiian chili) was cultivated in these experimental aquaponic systems and analyzed for capsaicin content. The purpose of this investigation was to: 1) obtain baseline water quality criteria 2) remediate pH for ammonia bio-filtration and pepper yield in recirculating aquaponic system in order to compare buffering capacity and understand treatment effect, and 3) quantify and compare capsaicinoid concentration between treatments using Rapid-High Performance Liquid Chromatography (r-HPLC) for quality analysis. This work helps address the need for combined approaches to complex agricultural research questions and food sustainability.|
