The Panel considered the following possibilities for the cause of crustacean mortality:
Disease or Parasite.
Chemical Toxicity from land sources and including Pyridine.
Harmful Algal Bloom
Capital Dredging - to create a new channel or berth.
Maintenance Dredging - for the continued operation of the port.
They concluded that the most probable cause of mortality was disease or parasite, which was rated as likely as not (33 to 66% probability)
Chemical Toxicity was rated as very unlikely (<10% probability)
HAB was unlikely (<33% probability)
Capital Dredging was exceptionally unlikely (<1% probability) and no capital dredging was carried out before the initial mortality event.
Maintenance Dredging was rated as very unlikely (<10% probability) and no Pyridine was found whatsoever during ongoing monitoring at the time by York University.
