Abstract
Armoured catfish Pterygoplichthys pardalis is an endemic fish from the Amazon basin (Brazil) and currently is the top ten target species in the regional fisheries. A total of 1200 samples were collected monthly from March 2011 to February 2012 with an average length of 28 ± 2.57 cm and average weight of 441.57 ± 103.37 g. The growth stock parameters for this species (Wt = 0.431227 * Lt2.08637; M = 0.93 year-1; F-Estimated = 0.91 year-1; F-10 = 3.02 year-1; A0.95 = 7.31 years; K = 0.41 year-1; Tr = Tc = 1.92 years; Lc = 21.14 cm; L∞= 38.85 cm; W∞ = 869.76 g) and exploitation rate (E-Estimated = 0.50; E-10= 0.80) reveal that its stocks are not being overfished in the study area. The baseline information obtained in this study can help support fisheries management strategies of P. pardalis, especially regarding the potential implementation of a policy to increase landings of individuals larger than 22.3 cm length. However, before making a final decision, it is necessary to carefully examine the available information and evidence aimed at sustainable fishing management and conservation of their stocks, which is of great cultural, social and economic importance for Amazonian peoples.

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 it
