Abstract
Gelatinous zooplankton can cause fish mortalities and economic losses for aquaculture companies. While protective measures against jellyfish blooms are increasingly implemented, free-floating tentacles have not been considered. Tentacles with active cnidocysts, both whole and fragmented, can cause potential damage to fish for an unknown duration after the jellyfish bloom has passed. In this pilot study, we measured for how long detached tentacles of the lion’s mane jellyfish Cyanea capillata can cause injuries/catch zooplankton prey. Controlled experiments were conducted in late summer 2007 using in situ collected specimens from northern Iceland. Jellyfish tentacles maintained their full ability to capture brine shrimps Artemia salina for 24 d. However, no prey could be immobilised from Day 26 onwards. To our knowledge, this is the first experimental evidence showing how long cnidocysts in tentacles can catch prey and thus potentially harm aquaculture fish after detachment (about 3.5 wk); this information should be considered when making any hypothetical risk assessment.

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
