Marine pest found at Great Barrier
An invasive marine pest has been found at Port Fitzroy and Auckland Council’s biosecurity team want to know if you’ve seen it.
The Mediterranean fanworm (Sabella spallanzanii) is established in the greater Auckland region, but this is only the second time it’s ever been reported at Great Barrier.
Biosecurity team to investigate
Auckland Council’s biosecurity team will carry out a dive survey in early April to investigate and determine the extent of the infestation.
Samantha Happy, Auckland Council’s Marine Biosecurity Advisor says Mediterranean fanworm is a threat to the island’s native biodiversity and aquaculture.
“It forms dense colonies, displaces native species and disrupts natural ecosystems. The species fouls and spreads on the hulls and niche areas of boats. It also grows on other marine structures and natural substratum including shells and rocks.”
“Unfortunately fanworm is established in much of the east coast of Auckland, but we’re not sure how far spread it is at Great Barrier."
"We will check marine structures such as moorings and wharves to find out how established it is around Great Barrier.”
