原始语种摘要: There is a need for sustainable, efficient, and productive agricultural practices. Goals to improve these practices include reducing water consumption, increasing vegetable culture density, and maximizing livestock feed conversion efficiency. Aquaponics offers the potential to address these goals with intensive production of fish protein and vegetable biomass within one recirculating system. This study explores the relationship between pH and the biomass yield of lettuce (Lactuca sativa cv. Ridgeline Romaine) grown in an aquaponics system with Nile tilapia (Oreochromis niloticus). Optimal pH for aquaponics production has not been clearly established. Four treatments will be studied: a hydroponic control at pH 6.0, and three aquaponics units at pH 6.0, 7.0, and 8.0. Water within each 50L...
