Abstract: Carassius auratus is an omnivorous organism resistant to their handling, so it is a popular specie that accept a widely food variety like leaflets, live food or pellets. The Biofloc technique system was considered as efficiency alternative, which supply nutrients that can be reused or recycled. One hundred and twenty juvenile organisms of C. auratus were used with a mean length of 5.9 ± 0.95 cm and weight of 4.2 ± 1.08 g. The juveniles were fed with commercial diet (Wardley), with a protein content of 45% and were supply 10% of their body weight. The food quantity was adjusted every 15 days. Also, were supply a different carbohydrates sources: molasses, coffees remain and dry moringa in C/N ratio of 20:1. Every 15 days, biometry (weight and length) were taken to obtain absolute and instantaneous growth rates and condition factor until 120 days. At end of experiment it was observed that carbon source molasses had the best results in weight/length ratio with respect to coffee and moringa. With respect to condition factor (KM), all experiment diets presented highest values than initial KM. Control diet showed better weight/length ratio, although this diet showed lowest values in length and weight.
