Pago Pago, AMERICAN SAMOA — The Department of Marine and Wildlife Resources (DMWR) is currently conducting an in-depth investigation into a concerning incident involving the discovery of approximately 300 dead fish floating in the waters adjacent to the marina at Pago Pago Harbor. This find was reported to the DMWR on Sunday, June 8, 2025, prompting an immediate response.

In an official press statement, the DMWR is actively seeking information from the community regarding this unusual occurrence. A specialized team was dispatched to the site to carry out a thorough examination and collect various samples, including a particularly decomposed specimen for laboratory analysis.

Preliminary observations have revealed no immediate signs of distress in other marine wildlife inhabiting the area, which is a positive indication; however, the exact cause of the fish die-off remains elusive.

The incident has also been communicated to the American Samoa Environmental Protection Agency (AS-EPA), which will provide additional support in investigating potential environmental impacts.

Initial testing focuses on measuring phytoplankton concentrations — these microscopic, plant-like organisms are crucial indicators of water quality. Ongoing testing efforts are in place, and the timeline for determining the exact cause of the fish mortality is currently undetermined.

Notably, the condition of the fish suggests they may have been deceased for an extended period prior to their discovery. While the incident occurred near the marina — a location not typically designated as a primary swimming area — the DMWR strongly advises members of the public to exercise heightened caution when engaging in recreational activities in the adjacent waters of Pago Pago, Utulei, and Fagatogo.

In an effort to ensure public safety, the AS-EPA will be conducting comprehensive tests to evaluate bacterial levels in the water. It is important to note that certain bacteria are naturally present in marine ecosystems. However, should elevated bacterial concentrations be detected, both agencies are prepared to take further action to protect public health.

This advisory serves as a precautionary measure, as there have been no additional incidents of fish die-offs reported since last Sunday.

However, given the situation's urgency, test results may need expedited processing, and there may be a requirement for additional overtime to maintain consistent monitoring efforts.

The public will be promptly informed as further updates become available.

For any inquiries or to report concerns regarding this incident, please do not hesitate to contact the DMWR at (684) 633- 4456.
