California Aquatic Invasive Species (AIS)
Invasive Seaweeds and Hull Fouling Species
Laticorophium baconi - Visit ITIS for full scientific classification.
- Occurs in marine intertidal areas.
- Attach via mud tubes to a variety of surfaces including vessel hulls in marinas.
Invasion Pathways and Distribution
- Spreads to new areas by attaching to vessel hulls.
- Unknown origin.
- Widespread throughout the Pacific ocean.
- Also found near China, Australia, Mexico, and Tasmania.
- These tube-dwelling amphipods are copper tolerant, and form dense aggregations on boat hulls.
- The muddy tubes create a non-toxic foundation for less copper tolerant fouling species to attach and live.
- This fouling growth roughens the hull’s surface, creating friction or “drag” that slows sailboats and increases fuel consumption for powerboats.
