Potential Domoic Acid (Neurotoxin) Producing Phytoplankton Pseudonitzschia in Indian Coastal Water - do We Need to Care?
Bibliographic record
Abstract
Pseudonitzschia species are potential domoic acid producers, a neurotoxin, responsible for the infamous human HAB intoxication at Prince Edward Island, Canada in 1987, costing human lives. Global warming has widened the reach of these phytoplankton species and it is being reported in Indian waters. We report the occurrence of ten Pseudonitzschia species in the northwestern coastal waters of India, out of which, seven are potential domoic acid producers. The question arises, are we vulnerable to HAB (Domoic Acid) toxicity? In light of the observation that Pseudonitzschia dominates the coastal waters of Veraval and its abundance is increasing with time, the present study briefly synthesizes the available information on the ecology, metabolism, and other relevant knowledge related to the domoic acid production by Pseudonitzschia and assesses the risk of human intoxication through trend and forecast analysis with the possible preventive measures required.

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.
