Live food produced by Biofloc in the breeding of Oreochromis aureus

Abstract

Live food produced by Biofloc was investigated in the rearing of Oreochromis aureus at the SL04LA04 Aquaculture Laboratory-Fisheries Department of the National University of Trujillo in 2021. Biofloc production was carried out in 1 m3 culture systems. Two treatments with different carbon sources T5-molasses and T6-banana flour and a nitrogen source with an aeration system under indoor conditions were used for the production of live food that was used in the rearing of tilapia. The live food evaluation consisted of the identification and quantification of phytoplankton and zooplankton composition. Phytoplankton was obtained with the predominance of Chlorella sp. and the zooplankton was formed by ciliates, rotifers, nematodes, oligochaetes and mosquito larvae. It is concluded that in both treatments with molasses and plantain flour, live food consumed by O. aureus was formed.
