Ecology and epidemiology of the striped shrimp, <i>Pandalus montagui</i> Leach, 1814 (Decapoda: Caridea), in the northern Labrador Sea, Davis Strait, and Ungava Bay, Canada
Bibliographic record
Abstract
Abstract Despite a fishery with annual landings valued at over $50 million CAD, very little knowledge has been gathered about the ecology of the striped shrimp (Pandalus montagui Leach 1814) in the Canadian northwestern Atlantic. This information is nevertheless considered essential for developing appropriate management actions for the fishery. We used survey data collected from 2005 to 2020 in the northern Labrador Sea, Ungava Bay, and Davis Strait to examine sizes, stages of maturity, size of transition, and evidence of parasites in the striped shrimp. We also investigated potential ecological drivers affecting the presence of parasites and size of transition. We found shrimp were substantially larger than previously observed in nearby habitats. The size of transition did not remain constant throughout the time series, and instead, was a function of the average size of females and the amount of preferred habitat in the previous year. The probabilities of individuals exhibiting black gill or black shell disease, or being infected with a bopyrid parasite were generally related to sex, depth, temperature, salinity, latitude, and shrimp density. The large sizes observed in the study area and the apparent plasticity of the population to environmental changes indicate that this species should be closely monitored in the future in relation to exploitation pressure and climate change.

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.
