Abstract
A review of small-scale fisheries of marine crustacean is here presented, indicating the main biological traits of the target species, levels and methods of capture, prices and markets, as well as fishing regulations. Edible barnacles are exploited in Spain, Japan, and Chile with low levels of capture (<500 t per year) and can be sold at high prices in the Iberian market. Stomatopods (mantis shrimps) are captured in the vicinity of the river mouths through trawl fisheries in Mediterranean Sea and in the western Indo-Pacific. Their landings fluctuate between 4,000 and 7,000 t per year, with levels of overexploitation reported for some Asian fisheries. A recent harvesting of sandhoppers (amphipods) has been reported from sandy beaches of Chile for aquarium food, with annual yields of 10–15 t dry mass. Other amphipod species (lysianassoids) are exploited in Canada mainly for fish food. These fisheries are characterized by a lack of biological and fishing parameters, management measurements, and regulations of the exploitation of their natural populations. However, in the cases of the European fisheries (stalked barnacles and stomatopods), some regulations have been implemented, such as closing periods, extraction quotas, and minimum legal sizes. Ecological studies are necessary to evaluate the possible impacts on biological interactions and food webs on the populations of the commercial extraction in these fisheries.

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.
