A SOLUTION FOR DELAYED IN VITRO FERTILIZATION OF
Bibliographic record
Abstract
Coho salmon ovarian fluid can be used for delayed in vitro fertilization of zebrafish eggs. Thus, it can be useful for sequential fertilization of small batches of eggs or for procedures where manipulations of eggs prior to fertilization are desired. Eggs can be squeezed from a female zebrafish, placed in a small amount of coho ovarian fluid, and held at room temperature, with fertilization rates of up to 85% still obtainable after one hour. Various batches of ovarian fluid have varying abilities to preserve zebrafish eggs in a fertilizable state. To make coho ovarian fluid available to other zebrafish researchers, we have supplied it to a commercial distributor in the USA. We collected coho ovarian fluid in Vancouver, B.C., Canada. We tested individual batches and shipped it to SeaTech Bioproducts, who are now selling it for $20 /ml. This alleviates the difficulties we were experiencing with sending the ovarian fluid through customs to zebrafish labs in the USA.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
