Abstract:
The growth and feeding efficiency of Astronotus ocellatus (Cichlidae) Melanochromis sp Cyprinus carpio (Cyprinidae), Astronotus ocellatus (Cichlidae) and Oreochromis niloticus (Cichlidae) fed with protein levels ranging from 25-40% in a Biofloc culture, whose carbohydrate source was moringa powder (0.01%), was evaluated for 180 days. The feeding frequency was twice a day (10% of the biomass, divided into two portions). All the fish in the study showed weight and length gain and this is observed with the KM value shown. Melanochromis sp. showed the lowest values of AGR in length and weight gain (0.033 cm and 0.865 g day-1). The IGR value showed a positive increase with 1.081-1.876% per day for length and 2.756-3.259% per day for weight. The FCF values showed values between 0.346-0.394, while for FCE values showed an increase of 253.60-289.08%. This experiment carried out on these species allows the production of ornamental species to be cultivated in the Biofloc system, considering that it is important to carry out tolerance studies on the concentration of organic matter in the cultivation of other ornamental species that are cultivated commercially.
