Microalgae Chorella sp. in biofloc Penaeus vannamei culture [Dataset]

Abstract

Biofloc systems improve water quality and add nutritional value to aquaculture production through complex microbial and planktonic communities, in which the inclusion of microalgae can enhance nutrient recycling and overall system functionality. This study evaluated the inoculation of microalgae in biofloc systems for Penaeus vannamei under different photoperiod regimes. In the first experiment, Chlorella sp. under 16:8 and, particularly, 12:12 photoperiods established stable populations, increased biofloc biodiversity, and improved the mineral profile of the system. In the second experiment, Chlorella sp. persisted for up to 32 days following a single inoculation, reduced nitrate accumulation, and enriched the biofloc with polyunsaturated fatty acids associated with immune function. Although no consistent effect on animal growth was observed, the results highlight the interaction between water quality, biofloc composition, and zootechnical performance. Overall, Chlorella sp. under a 12:12 photoperiod enhanced the ecological and nutritional quality of the biofloc, although further studies are required to optimize inoculation protocols and maximize productive benefits.
