Production performance of sutchi catfish Pangasianodon hypophthalmus S. in restricted feeding regime: effects on gut, liver and meat quality
Bibliographic record
Abstract
The experiment was carried out to evaluate the production performance of sutchi catfish, Pangasianodon hypophthalmus in restricted feeding regimes and their effects on gut and liver indices and body composition. Four feeding regimes were evaluated: fed to satiation twice per day (treatment daily feeding); 1-day food deprivation and 1-day feeding (treatment 1D-1F), 2-day deprivation and 2-day feeding (treatment 2D-2F) and 5-day deprivation and 5-day feeding (treatment 5D-5F). Fingerlings (mean weight 37 ± 3 g, mean total length 18 ± 2 cm) were stocked in replicated earthen ponds at a density of 25 000 ha−1 and cultured for 18 weeks during which commercial diet (33% crude protein) were delivered to apparent satiation on the feeding day according to the treatment. Results showed that the daily feeding and 1D-1F treatments resulted in similar individual weight gain (515–536 g) and net fish production (10 954–11 387 kg ha−1) as compared with treatment 2D-2F (weight gain 309 g; net production 6700 kg ha−1) or treatment 5D-5F (weight gain 251 g; net production 5651 kg ha−1). While fish body protein levels were not affected by food deprivation, lipid contents were lowest in treatments 2D-2F and 5D-5F. The study concluded that sutchi catfish could be cultured in alternate-day feeding regime without any negative effects on production and meat quality of fish resulting in a net profit of USD 2750 ha−1 pond.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
