Evaluation of Replacement Feeds for the Fry Feed Kyowa for Larval Walleyes
Bibliographic record
Abstract
Abstract Because Fry Feed Kyowa (FFK) was the standard and the only commercially manufactured starter feed suitable for intensive culture of larval walleyes Sander vitreus, it became imperative to evaluate other commercial feeds after FFK importation to the USA was banned to prevent the spread of bovine spongiform encephalopathy. A project was undertaken at the Rathbun Fish Culture Research Facility (Rathbun), Moravia, Iowa, and Iowa State University (ISU), Ames, using a single-factor experimental design with Lansy and Epac feeds (INVE Aquaculture, Inc., Ogden, Utah) and Gemma feed (Skretting, Vancouver, British Columbia). Walleyes were cultured at both sites from 3 to 28 d posthatch to evaluate the feeds. Performance indicators included presence of feed in gut, gas bladder inflation, survival, total length (mm), weight (mg), growth rate, and incidence of deformities. At both sites, survival was 2.6–3.6 times greater for fish given Gemma than for fish given the INVE feeds; the difference was significant at Rathbun but not at ISU. Length, weight, and growth rate at both sites were also significantly greater for Gemma-fed walleyes than for INVE-fed fish. Weight advantage produced by Gemma was 192% at ISU and 534% at Rathbon. Performance measures of fish given Gemma were similar to those of fish fed FFK in previous years.

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.
