DIET OF WHITE PERCH (MORONE AMERICANA) IN THE RICHIBUCTO ESTUARY, NEW BRUNSWICK
Bibliographic record
Abstract
The Richibucto Estuary, located in the southern Gulf of St. Lawrence, is rearing habitat for a population of white perch (Morone americana), as well as for young-of-the-year striped bass (M. saxatilis) which immigrate from the nearby Miramichi Estuary. In this study we compared the diet of white perch caught in the Richibucto Estuary to a previously published account of the diet of young-of-the-year striped bass in the Miramichi Estuary. One hundred and fifteen white perch of 26–168 mm total length (TL) were collected from the Richibucto Estuary between 25 June and 10 October 1998 by onshore beach seining at 10 sites. Eighty-nine percent of their stomachs contained food. Sand shrimp (Crangon septemspinosa) were found in 69–79% of stomachs and constituted at least 80% of total dietary weight for white perch = 50 mm TL. Copepods (cyclopoids and the large calanoid Eurytemora sp.) constituted almost all of the diet of small white perch (<50 mm TL) found in low salinity but in higher salinities (11–20‰) mysids and sand shrimp were also important components of the diet. Polychaete worms and amphipods (Gammarus sp.) were minor constituents of the diet of both size categories of white perch. The diet of young-of-the-year white perch in the Richibucto Estuary was found to be similar to that of young-of-the-year striped bass studied previously in the Miramichi Estuary.

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.
