Scientists Warn Stranded Ships Could Spread Invasive Species Globally

Marine scientists are warning that commercial vessels stranded or anchored for extended periods pose a growing threat to global marine ecosystems by facilitating the spread of invasive species. When ships remain stationary, their hulls accumulate thick layers of marine organisms, known as biofouling. Once these vessels resume international transit, they can transport non-native species across oceans, potentially disrupting local biodiversity, damaging fisheries, and introducing ecological hazards to foreign waters.

• Prolonged idle times and port delays allow marine organisms, including algae, mollusks, and barnacles, to heavily colonize ship hulls.
• Resuming voyages enables these colonized vessels to transport non-native species directly into vulnerable marine habitats worldwide.
• Invasive marine species can outcompete indigenous wildlife, disrupt marine food webs, and cause significant economic damage to coastal infrastructure and fisheries.
• Researchers urge the maritime industry to implement stricter hull-cleaning protocols, monitoring, and enhanced international biosecurity standards.
