A variation on the IMTA theme: a land-based, closed-containment freshwaterIMTA system for tilapia and lettuce

摘要

A study was conducted to measure the effects of formulated diets on the growth of tilapia (Oreochromis sp.) and lettuce (Lactuca sativa) in an innovative freshwater IMTA system. Tilapia diet was enriched with different ratios of an organic-inorganic mixture (0%, 15% and 30%, OlM) to provide essential basic ingredients (proteins, fats, fibers, etc.). Based on investigated biotic and abiotic factors, both tilapia and lettuce showed high positive response to the enriched diets. The OIM30 diet provided the best growth for tilapia. The best nutrient bioremediation was achieved with the OIM15 diet.
