Inclusion of camelina meal as a protein source in diets for farmed Atlantic cod<i>Gadus morhua</i>
Bibliographic record
Abstract
Camelina meal Camelina sativa (CM) is a potential protein source in aquaculture feeds, because of its crude protein level (39%) and essential amino acids. Two feeding experiments were conducted with Atlantic cod Gadus morhua. Cod in Experiment I (19.4 g fish−1) were fed diets with 0%, 12% or 24% CM for 9.5 weeks at 10°C; and cod in Experiment II (14.4 g fish−1) were fed diets with 0%, 15%, 30% or 40% CM for 13 weeks at 10°C. Growth, lipid and amino acid tissue composition were compared amongst cod fed varying levels of CM. In Experiment I, cod could tolerate the highest level of CM inclusion (24%) without affecting growth compared to cod fed the control diet. In Experiment II, growth performance was significantly affected at 30% CM inclusion compared to the control treatment, and cod fed 15% CM displayed some signs of depressed growth (reduced feed intake and weight gain). Both treatment and duration were interacting factors (P = 0.015) that determined growth performance when comparing both experiments. Muscle tissue composition was relatively unaltered with less than 30% CM inclusion; however, multivariate statistics revealed significant differences in muscle tissue fatty acid composition between cod fed 40% CM and the control diet. The tissue amino acid profile was generally unaltered because the dietary amino acid profile was consistent after CM inclusion. A few antinutritive compounds in CM may have affected palatability in diets with greater than 30% CM inclusion, which may have resulted in reduced growth performance.

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.
