Preliminary finding have revealed that the cause of death may be linked to a disease or could be due to ingestion of harmful food organisms.
IMA has stated that from observations, the mortality rate is very high especially among the species known as the white mullet.
This suggests that this is not a typical fish kill since fish kills will generally affect other species.
Examination of the mullet carcasses revealed that they were heavily infected with parasitic nematodes and that they are not yet in spawning condition.
The Institute of Marine Affairs is collaborating with the University of the West Indies to determine the exact cause of the mortality.
