The prolonged anchoring of over 1,500 ships, following the closure of the Strait of Hormuz, leads to “biofouling” – the accumulation of marine organisms like mussels and barnacles on their hulls. When these ships resume normal trade routes, the biofouling creatures may be transported globally, potentially causing an unprecedented “super-spreader” event for invasive species. Researchers highlight the significant ecological and economic damage these invasive species can cause, citing examples such as harmful algal blooms and the rapid reproduction of barnacles. Scientists are urging authorities to strengthen ship biofouling management and expand monitoring at high-risk ports to abate this extraordinary global biosecurity threat.

Biologists say cargo ships stranded in Gulf may carry highly potent invasive species around the world as trade resumes

Such organisms may act as ‘reservoirs and vectors’ for marine parasites and pathogens, study warns
