Effect of Commercial Feed on Sexual Maturity of Two Tilapia Species (<i>Oroechromis niloticus</i> and <i>Oreochromis tanganicae</i>)
Bibliographic record
Abstract
An experiment was conducted for twelve weeks (90 days) in hapas inserted in the semi-concrete ponds to evaluate the effect of commercial feed on the sexual maturity of two tilapia species, Oroechromis niloticus and Oreochromis tanganicae . Results indicated that the final mean body weight was 73.65g for O. niloticus and 66.30g for O. tanganicae respectively. First maturity in both species was observed in the sixth week and the smallest fish matured at 34g and 73mm for O. niloticus , while for O. tanganicae , it was 42g and 111mm. Length at first maturity was 136mm for O. niloticus and 129mm for O. tanganicae . Maturity stages were macroscopically identified into three stages (immature, maturing and mature) and at the end of the trial, 73% of O. niloticus and 58% of O. tanganicae were in the reproductive process (mature). The gonadosomatic index (GSI) mean value for O. niloticus was higher than that of O. tanganicae . However, there was no significant difference (p>0.05) between GSI values.

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.
