Abstract: In Mexico the national production of ornamental fish takes place in 23 states, where 160 species and varieties are cultured for diverse interests, within these species is the koi carp. The experiment took place in the laboratory of Live Food Production of Universidad Autonoma Metropolitana, Unidad Xochimilco. The carps were fed with particulate food of 2mm of diameter with 45% of protein. Four carbon sources were used: coffee, moringa, macroalgae and yucca. The experiment lasted six months. The carps that obtained the highest weight were the ones with Moringa as carbon source with 909.48 ± and the lowest were the ones with coffee with 403.47 ±0.20 g. All final weights showed significant differences (P<0.001) in the four experimental systems. The use of vegetable flours (yucca, moringa and macroalgae) as carbon sources for flocs production and their capacity to maintain good water quality in Biofloc system, are a good alternative for ornamental fish culture.
