Abstract
Thirteen morphometric and seven meristic characters of the cichlids species Coptodon zillii and Oreochromis aureus were studied from three localities, Qurna, Hartha, Abu Al-Khaseeb, on Shatt al-Arab River, Basrah, Iraq. Samples revealed no significant differences between genders. Values of morphometric and meristic traits increase from the southern to northern reaches of the river. Based on cluster analysis and PCA, the Shatt al-Arab River samples of the two species C. zillii and O. aureus were clearly separated into two distinct groups. Group I, Qurna and Hartha, represents the northern and middle regions of the river and GII represents the southern region, Abu-Al-Khaseeb. Possible reasons for such differentiation among populations are discussed, and the integration of research on these species among the countries neighboring Iraq is required. This study gives information to fishery biologists about morphometric characters of C. zillii and O. aureus from Shatt al-Arab River to assist in planning of conservation strategies for these fish species.

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 it
