During the trapping process, Manaaki Te Awanui also found increased numbers of the Asian paddle crab compared to previous seasons. This is an aggressive marine pest that can carry diseases, eat vital shellfish species and compete with other native crabs.
Both the Japanese mantis shrimp and the Asian paddle crab are detrimental to our marine habitat and native species. As summer approaches, there are precautions we can take to ensure they do not spread further.
What can you do to prevent the spread of marine pests?
• Clean and dry any marine equipment (e.g. ropes, lines and pots) before using these in a new area.
• Inspect areas on your boat that retain water for signs of marine life.
• Check for aquatic weeds tangled around anchors, trailers and other equipment.
• Keep your boat bottom and any niche areas clean (no more than light slime, all the time).
• Check your hull before you travel to a new area, every time.
• If your boat is heavily fouled, haul it out. Cleaning underwater will only spread any pests that may be hiding there.
