Coastal catch transects as a tool for studying global fisheries
Bibliographic record
Abstract
Abstract We present a new, intuitive approach for the representation of fisheries catches within profiles perpendicular to coast of the E xclusive E conomic Z ones ( EEZ ) of countries, or of L arge M arine E cosystems ( LME ). These ‘catch transects’ show where catch is extracted in the water column and near the sea bottom on plots of log‐bathymetry versus log‐distance offshore and thus allow for representation of the catch density of pelagic and benthic fisheries. Hence, they also allow direct visual comparison of the intensity of fishing through time and space. The C alifornia C urrent, N orth S ea and the S outh C hina S ea LME s and the EEZ s of A ustralia, C anada, C hile, C hina, I ndia and T hailand are presented as examples, revealing the general intensification and extension of fishing offshore and into the depths over the decades from the 1950s. Catch transects reveal how these trends have accelerated in some areas, but surprisingly have reversed themselves in some others. It is proposed that these catch transects will be particularly useful for communicating the results of large‐scale fisheries studies to a wide spectrum of groups ranging from the fishing industry to the general public.

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.
