Effect of Water Temperature and Flow Rate on the Transmission of Microsporidial Gill Disease Caused by Loma salmonae in Rainbow Trout Oncorhynchus mykiss
Bibliographic record
Abstract
Two studies were designed to quantify the effect of water temperature and flow rate on the transmission potential of the important salmonid gill pathogen, Loma salmonae. Using survival analysis, increased water temperature and low flow rates were determined as risk factors for the transmission of microsporidial gill disease caused by L. salmonae in rainbow trout Oncorhynchus mykiss. Fish were experimentally infected with L. salmonae via a cohabitation exposure model and monitored for the development of branchial xenomas. On any given day, fish held at 11°C and 15°C had a hazard ratio equal to 0.80 and 0.68, respectively, for the development of branchial xenomas compared with fish held at 19°C. From the flow rate trial, fish housed in a low flow tank (0.83 L/min) had an increased chance of developing branchial xenomas when compared to fish in tanks at normal (1.67 L/min) and high (2.5 L/min) flow rates with hazard ratios reported as 0.69.

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.
