Effectiveness of <i>Mysis diluviana</i> as a Substitute for Fishmeal in Formulated Aquafeed for Fingerling Rainbow Trout
Bibliographic record
Abstract
The present study explored the potential of wild Mysis diluviana , a widespread freshwater crustacean that is also invasive in many lakes, to serve as a substitute for fishmeal in the formulation of salmonid aquafeed. M. diluviana , harvested from Okanagan Lake in British Columbia, Canada, had a high protein content, with crude protein making up 53% of its dry body weight; lipids formed 32% of dry M. diluviana body weight. Fingerlings from two distinct strains of rainbow trout were fed for 60 days with one of three diet treatments: experimental feeds in which 25% or 50% of the fishmeal ingredient was replaced with M. diluviana and a feed containing no M. diluviana . Feeds containing M. diluviana supported the same survivorship and similar or better fingerling growth as the fishmeal‐only feed, including fingerlings of a trout strain that are highly selective feeders. The amino acid and fatty acid composition of fingerling tissues at the end of the experiment was mostly indistinguishable among the three feed treatments. In addition, the tissue composition of fingerlings, such as the EAA : NEAA ratio and the amounts of SFA, MUFA, and PUFA, did not fully match the biochemical composition of their feeds, likely due in part to the capacity of freshwater salmonids for bioconversion of some amino acids into other less available amino acids. M. diluviana was therefore found to be an effective source of protein and lipid for fingerling rainbow trout and an effective substitute for marine fishmeal in trout aquafeed.

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.
