Why is it a problem?
- Larvae can travel long distances through ocean currents
- Can disturb habitats within local commercial, subsistence, and personal use fisheries
- Can cause dramatic change to species composition within rocky and inter-tidal ecosystems
- Tolerant of many different temperature ranges and salinities
- Can out-compete and prey upon many species native to Alaska
- If breeding populations established, this species could spread to many of the rocky shores of Alaska
How do I manage it?
- Learn to identify and report unusual sightings found on beach walks, fishing gear, growth/bio-fouling on boats, crab pots, or equipment
- Clean, drain and dry (3 day minimum) boots, nets, fishing gear, pots (shrimp or crab), motors, docks, and any marine equipment. Clean above the high tide line AND ensure wash water doesn’t drain back into the ocean when it rains or is hosed down
- Follow proper ballast water dumping procedures
- Be mindful of possible vectors through aquariums, food trades, or aquaculture
- Monitor for invasive species as a citizen scientist with Kachemak Bay National Estuary Research Reserve
