Abstract
Estuaries and lagoons along the South African coast provide the only sheltered conditions on an otherwise high energy coast. The juveniles of numerous marine species, some of which are dependent on estuaries, utilize these as nursery grounds where they remain until attaining maturity. Currently most KwaZulu-Natal estuaries are being impacted upon by changing land-use patterns in their catchments and developments along their shorelines. The nursery function of many has substantially diminished over the past 30 years. Two major deep water harbours, Durban and Richards Bay exist on estuarine embayments in KwaZulu-Natal. Preliminary investigations showed that they are playing an important role as nursery areas for juveniles of marine fish and penaeid prawns normally found in estuaries. This role could be enhanced by the implementation of an environmental management policy for each harbour in conjunction with designating sites, not due for development, as natural areas. Manipulation of the latter areas could further increase the importance of these harbours for juvenile marine organisms which normally utilize estuaries along the KwaZulu-Natal coast.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
