harrytom 666 Posted April 27 Share Posted April 27 Exotic caulerpa has been found at Waiheke Island and while there is no Controlled Area Notice at this location, Ngāti Paoa has imposed a rāhui on disturbing the seabed or anchoring within 1 nautical mile (1.8 kilometres) of Thompson's Point or Onetangi Bay.4 days ago https://www.ngatipaoaiwi.co.nz/media-release-caulerpa-2.html Quote Link to post Share on other sites

K4309 320 Posted April 28 Share Posted April 28 Giving this some thought, and now that we know caulerpa is at Rakino / Woody Bay, which is one of my go to / fav anchorages, would I anchor on caulerpa if I knew it was there - no. Not in the foreseable future, if I could avoid it. Normally in Woody Bay I can see the bottom, and it is clear sand. I've dove on it last year (had fishing line around the prop) and there was no caulerpa in the anchorage. I went spear fishing along the reef on the south side, very good current and productive fishing, did not see anything like caulerpa then. Whilst saying I'd avoid it if I can, it is apparent there is going to be a point in the not too distant future where it is going to be very hard to avoid anchoring on it. In which case I shall be taking the utmost care to check my anchor and chain (which I do already, as I have one of those low-tech boats where I need to work the anchor winch at the bow, watching the anchor and chain come up, as opposed to a remote cockpit jobby.

I'll bet you a good bottle of whiskey it was at the Mokes first, it's come down on the East Auckland current from offshore, and it has spread from the Mokes to all points South. Noting it was found at the Barrier and the Mercs first, and first findings tend to be where there is higher foot-traffic, so to speak, as in people to actually find it. Noting it is naturally occurring in large parts of the Pacific and Australia. All you need is one of those La Nina years to set up the ocean currents and water temp, and hay presto - magic - killer algae. Nothing to do with yachts importing it. 2 Quote Link to post Share on other sites

K4309 320 Posted June 10 Share Posted June 10 RNZ understands the suspected caulerpa was found near boat moorings - but Omaha Cove also has a wharf used by commercial fishing boats, including those permitted to work in the controlled areas around Aotea Great Barrier where the pest is rife. Commercial cray fishers have been allowed to continue operating, setting cray posts INSIDE the CAN at Gt Barrier. Hence why Auckland Council thought Leigh Harbour might be a 'high risk' location for an outbreak. I understand the Barrier locals are highly traumatised that while they have been banned from collecting seafood, commercial fishers from the mainland continue to operate right in their faces. But for some reason, while commercial interests set cages on the caulerpa infested seafloor, recreational boaties are banned from anchoring and blamed in the media for caulerpa's spread... 1 1 Quote Link to post Share on other sites

A roughly one square metre patch of exotic caulerpa was found in Leigh's Omaha Cove, north of Auckland, by divers carrying out routine surveillance on 7 June. The fast-growing weed, often described as the world's worst invasive marine pest, is already well established at Aotea Great Barrier with other infestations around the Hauraki Gulf, the Bay of Islands and the Coromandel Peninsula. However, when a different dive team went back to Omaha Cove, the patch of caulerpa seemed to have gone AWOL. Liz Brooks, of Auckland Council, said divers returned to the water on 12 June to treat the patch, but could not locate the caulerpa despite having GPS coordinates of the initial find. Divers resumed their search this week and, once the weed was located, would cover it with mats and dose it with chlorine. That technique had proven effective for treating small areas of caulerpa in the past. "Divers will also continue to look for any other patches of exotic caulerpa, in addition to checking for other marine biosecurity pest presence in these areas," Brooks said.
