Abstract
The objective of the current study was to analyze the performance of white shrimp fed using three feeding systems: manual, time feeders and sound feeders, in thirteen commercial semi-intensive farms in three areas of Guayas province (Ecuador) using 535 production lots during the period 2015~2017. The size of the ponds ranged between 3 and 23 hectares, with a depth of 1.2 m, in which the exchange of water was around 1 % a day. The initial weight of the shrimp was 0.04~0.29 g, and stocking density was around 10 shrimp per square meter. The three feeding systems used commercial diets with 35% protein content. The time feeder system gave a higher shrimp yield (1 631 kg/ha) than manual feeding (1 539 kg/ha) and the sound feeder system (1 483 kg/ha). The best results for survival were obtained with the manual system (61.7%) and the time feeder (62.9%) in comparison to sound feeder (57.0%). Current performance results with acoustic systems were lower than reported by other authors, probably because the number of feeders per hectare was low, reducing the accessibility of shrimp to feed, in fact daily feeding supplied was not improved as has occurred in other studies.

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.
