Officials Respond to Anegada Fish Die-Off
Environmental officials and local non-profit Beyond the Reef have launched an emergency response following a fish die-off at Flamingo Pond in Anegada. Investigations confirmed that heavy Sargassum seaweed decomposition depleted oxygen levels in the water. A protective boom has been installed as the region braces for record seaweed levels this season.
Environmental officials in the Virgin Islands have launched a coordinated intervention at Flamingo Pond in Anegada following a fish die-off linked to heavy accumulations of Sargassum seaweed. The Ministry of Environment, Natural Resources and Climate Change, working in partnership with the Department of Agriculture and Fisheries and local non-profit organization Beyond the Reef, intervened after significant influxes of seaweed were reported along the coastline.
Ministry officials identified Sargassum decomposition as the primary cause of the event, explaining that rotting seaweed impedes natural water circulation and severely depletes dissolved oxygen, creating fatal hypoxic and hypersaline conditions for resident fish. Director of Environment Angela Burnett Penn emphasized the vulnerability of local marine environments, noting that the incident serves as a stark reminder of the ecological damage caused by severe Sargassum inundation.
She praised the swift volunteer support provided by Chris Juredin and the team from Beyond the Reef, who installed a specialized boom across the entrance and assisted in clearing rotting seaweed to facilitate water flow. Technical teams from the Ministry and the Department of Agriculture and Fisheries conducted site visits and collected water samples to evaluate water quality.
Environment Officer Atoya George confirmed that laboratory testing verified oxygen levels had dropped to points unsurvivable for marine life. While follow-up testing showed slight improvements after the boom was deployed, oxygen levels remain low, requiring ongoing observation to assess the long-term effectiveness of the barrier.
The die-off comes amid broader regional concerns. Data from the University of South Florida Sargassum Watch System indicates that seaweed levels across the Atlantic and Caribbean basin have been tracking at historic highs, with projections pointing toward a record-breaking season.
In response, the Ministry confirmed it will continue monitoring coastal ponds and vulnerable shorelines across the Territory to coordinate mitigation measures wherever necessary.
