Aquaponic systems of aquatic animal-plant are a model for conversion of waste into plant substrates and its efficacy is estimated depending on the type of feed given. This study aims to investigate the effect of fermented feed in the circulating aquaponics system with catfish (Clarias sp.) on the growth of lettuce (Lactuca sativa L.). The study was carried out in a circulated serial aquaculture tanks containing catfish. Various inputs of fermented fish feed was applied including low concentration (6% of fish weight) and high concentration (9% of fish weight). The growth of lettuce, water quality, and total microorganisms were measured. As results, maximum length and width of lettuce were higher in supplementation of higher feed concentrations (9%), as well as tendency height and weight of plant clumps plant.
