Proximate composition of a powdered green biofloc from giant freshwater prawn culture (Macrobrachium rosenbergii) as a potential aquaculture nutrition source
Bibliographic record
Abstract
Green biofloc aggregates were filtered from two indoor tanks housing adult Macrobrachium rosenbergii. The bioflocs were generated through the supplementation of molasses as a carbon source at 48-hour intervals and continuous exposure to ambient sunlight. The biofloc mass was harvested using the membrane filtration technique. This filtered wet aggregation was then oven-dried and prepared into biofloc powder (<100 μm). Proximate analysis was carried out on this powder to determine its composition for comparison to commercial fish meal. It was found that the crude protein content of the biofloc powder was 27.53% and crude lipid was 5.28% which was lower than commercial fish meal (crude protein: 60.53% and crude lipid: 8.71%). However the low cost involved in producing the biofloc powder does not preclude it from being a possible candidate for consideration for total and partial replacement of fishmeal in formulated aqua feeds.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
