Growth, Reproduction and Sex Ratios in Oreochromis Andersonii (Castelnau, 1861) Fed with Varying Levels of 17α-Methyl Testosterone
Bibliographic record
Abstract
Three different doses (40, 60 and 90 mgMT/kg feed) of 17α-methyl testosterone (MT) were administered to Oreochromis andersonii.Growth, reproduction and sex ratios were evaluated.The fish raised on 60 mgMT/kg feed had the highest final mean weight and this was significantly different (P<0.05) from other hormone doses.Additionally, the 60 mgMT/kg fed fish had the lowest fecundity and reproductive effort.Histological examination of the gonads did not show any differences between the control and MT fed fish.The gross margin ratio (GMR) of the control group was the highest (P<0.05).The proportion of males in MT treated groups deviated significantly from the control group although the percentage of males obtained from the 40 mgMT/kg feed (93.4%) and 60 mgMT/kg feed (94.4%) fish was insignificant (P>0.05).Furthermore, the highest dose used produced a significantly lower (P<0.05)male proportion (79.3%) than the other treatments.The anabolic effect of androgen MT diminished over time.

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.
