VARIÁVEIS HIDROLÓGICAS FÍSICO-QUÍMICAS NA CRIAÇÃO DA TILÁPIA-DO-NILO NO SISTEMA RACEWAY COM DIFERENTES RENOVAÇÕES DE ÁGUA
Bibliographic record
Abstract
This experiment was carried to evaluate the hydrological alterations in the production of Nile tilapia (Oreochromis niloticus) in raceway, with different rates of water exchanges, to estimate the impact of this system on water quality. Four treatments with total exchange of water at 30, 90, 120 and 150 minutes were analyzed. A total of 1,500 fingerlings were used. They were reverted for male, fed three times a day with commercial extruded ration 36% and 32% of crude protein. The following hydrological parameters were evaluated: dissolved oxygen, temperature, alkalinity, pH, solids in suspension, turbidity, electrical conductivity, phosphorus, nitrite and nitrate. All tested treatments maintained the hydrological variables within patterns suggested for fish raising, rationalizing the use of water for cultivation.KEYWORDS: High water flow, Oreochromis niloticus, water quality, water total exchange.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
