VARIATION IN LIPID, PROTEIN, AND CARBOHYDRATE CONTENT DURING THE EMBRYONIC DEVELOPMENT OF THE CRAYFISH CHERAX QUADRICARINATUS (DECAPODA: PARASTACIDAE)
Bibliographic record
Abstract
Eggs of 20 females were sampled to analyze lipid, protein, and carbohydrate content during the embryonic development of Cherax quadricarinatus. Sampling was performed on recently spawned eggs to first juvenile stage. Ten eggs were sampled every 48 h during the first two weeks and every 72 h thereafter for biochemical analysis. Total proteins, lipids, and carbohydrates were measured. Proteins were the most abundant egg component (63.2%), followed by lipids (32.3%), and carbohydrates (4.4%). A steady decrease of lipid content was observed ( y = 895.38 − 9.93x, r2 = 0.94; y = lipid concentration, x = days). For proteins, two different depletion rates were observed, with the initial rate maintained for 30 days ( y1 = 1,443.0 − 4.46x1, r2 = 0.90) and an increased depletion rate after hatching ( y2 = 1,936.60 − 21.10x2, r2 = 0.96). Carbohydrates were always present as a minor constituent, and its concentration did not change significantly. Water content increased from 52% in recently spawned egg to 85% in juveniles. Energy equivalents were calculated from each component, and the overall energy expenditure is represented by the equation y = 13.86 − 0.11x (r2 = 0.95). Relevant morphological features for each sample day are indicated.

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.
