The Department of Marine and Wildlife Resources (DMWR) is investigating what appears to be a fish kill in Pago Pago Harbor that occured last weekend.
On Sunday, June 8, a local resident reported the discovery of approximately 300 dead fish floating near the marina at Pago Pago Harbor.
DMWR dispatched a team to investigate the incident and collect samples.
Water and fish samples—including one decomposing fish—were collected, for laboratory testing.
Preliminary observations found no signs of impact to other wildlife in the area.
The incident was also reported to the American Samoa Environmental Protection Agency (AS-EPA) for additional support.
Initial tests focused on phytoplankton levels (tiny plant-like organisms) in the water. Further testing is ongoing, and the exact cause of the fish die-off remains unknown. The condition of the fish suggests they may have been dead for some time before being discovered.
Although the incident occurred by the marina—not a primary swimming area—DMWR advises the public to exercise caution when using nearby recreational waters in Pago Pago, Utulei, and Fagatogo.
AS-EPA, which will test for bacterial levels, notes that some bacteria are naturally present in marine environments. However, additional action will be taken if high levels are detected. Both agencies emphasize that this announcement is a precautionary advisory and that no further fish die-offs have been reported since Sunday.
DMWR continues to monitor the area and will assess whether further federal assistance is necessary.
