An overview of a collaborative project to develop optimized diets for culture of triploid growth hormone transgenic Atlantic salmon (Salmo salar)
Bibliographic record
Abstract
There is growing interest in growth-hormone transgenesis (TG) and triploidy (TRIP) in salmon aquaculture to shorten production cycles using fast-growing, reproductively sterile animals. Since triploidy alters physiology of fish and TG salmon have significantly enhanced growth rates, it is likely that feed formulations for conventional non-transgenic (NTG), diploid (DIP) culture may not be suitable. It is possible that traditional formulations may not provide TG/TRIP fish with sufficient macronutrients to sustain rapid growth and dietary micronutrient levels may require adjustment to reduce possible skeletal irregularities associated with triploidy. Evidence suggests that TG/TRIP fish may utilize dietary nutrients more efficiently, providing an opportunity to reduce feedcosts and improve the economics and ecological sustainability of salmon culture. This presentation will review a collaborative project conducted between industry and government to characterize and improve growth performance and nutrient utilization of TG and NTG TRIP salmon. Several studies are in various stages of completion focussing on several life stages; including first-feeding fry (<30 g), juveniles (30-300g) and large fish (up to 1 kg). These studies will provide information to help determine if diets for conventional NTG/DIP salmon are suitable for reproductively sterile fish and where further improvements may be required. Preliminary results will be presented.

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.
