Occurrence of <i>Glugea pimephales</i> in Planktonic Larvae of Fathead Minnow in Algonquin Park, Ontario
Bibliographic record
Abstract
The microsporidian Glugea pimephales was found parasitizing larval fathead minnow Pimephales promelas in Scott Lake, Algonquin Park, Ontario. These fish were estimated to be 2-3 weeks posthatch and, given the development time of the parasite, must have acquired infection soon after commencement of exogenous feeding. Histological sections revealed that the parasite typically developed in loose connective tissue between the peritoneum and the dermis of the abdominal cavity, with protruding xenomas of up to 2.6 mm in diameter forming near the vent. Prevalence was estimated at 1% by divers performing snorkel surveys along the lake shoreline. Divers following schools of fathead minnow consistently reported that larvae with the obvious cysts wobbled during swimming and that infected fish were typically located at the back of the dispersing school. This case history joins a growing list of studies suggesting that fish can become infected with parasites soon after hatch, the potential importance of which has not been critically studied.

How this classification was reachedexpand
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.
