Ships stuck in the Strait of Hormuz region may be biosecurity risks when they leave. What can we do?
Elke Scholiers/Getty Images, CC BY The economic ramifications of the closure of the Strait of Hormuz are much discussed. But so far, the risk of ecological damage following a long blockade of ships has been overlooked. Our recent research shows the more than 1,500 commercial vessels that have been laid up in the Persian/Arabian Gulf since February pose a significant environmental threat because they have been accumulating marine biofouling species on their hulls. As the strait reopens, these…

-
Did not happen 45% Rapid Biosecurity Implementation
Global maritime and port authorities, spurred by the risk, swiftly implement mandatory pre-departure hull inspections and environmental DNA screening for all ships exiting the Gulf. This proactive measure effectively manages the immediate threat of super-spreader events upon reopening.
Watch for: The International Maritime Organization (IMO) issues a new, binding regulation on hull biofouling standards for Gulf-origin vessels. · Major global ports announce mandatory, subsidized environmental DNA screening checkpoints for Gulf-bound arrivals.
-
Did not happen 30% Staged Reopening with Health Monitoring
The reopening of the Strait occurs gradually, initially restricted to a small volume of vessels under intense, monitored quarantine protocols. International health and environmental bodies establish a temporary joint task force to oversee the first influx of traffic.
Watch for: A joint press conference is held by the UN Environment Programme and regional maritime security forces detailing phased reopening schedules. · Specific port authorities announce a 72-hour mandatory quarantine period for the first wave of incoming commercial vessels.
-
Did not happen 15% Minimal Regulatory Response (Status Quo Drift)
Economic pressure to restore trade outweighs immediate biosecurity concerns, leading to a rapid, less stringent reopening. Initial environmental monitoring reveals low-level, localized outbreaks that are managed reactively rather than preemptively.
Watch for: A major shipping consortium announces a full return to normal operating schedules without citing new biosecurity protocols. · Regional environmental NGOs release a preliminary report noting an observable spike in non-native marine species near a major receiving port.
-
Confirmed 10% Unexpected Maritime Incident Precludes Reopening
Before the biosecurity issue can be addressed, a major, unrelated incident—such as a significant, non-conflict-related maritime accident or an unexpected environmental hazard—forces a temporary closure or severe restriction on the Strait.
Watch for: A major international shipping news wire reports a catastrophic collision or pollution event near the Strait of Hormuz. · A government agency issues an emergency advisory halting all non-essential commercial traffic in the Gulf region.
