harrytom 626 Posted November 19 Share Posted November 19 Close the Mercs too. Bugger it, just close the gulf and ban tidal currents/easterly winds. If they did something 5 yrs ago might of helped rather than sit on ones hands. 2 Quote Link to post Share on other sites

If they did something 5 yrs ago might of helped rather than sit on ones hands. In the article they more or less acknowledge it was the big ships that caused the issue, yet they want to penalise boaties and yachites when the horse has clearly bolted. And you are right Harry, and in fact, they could close the Hauraki Gulf for a decade and the natural currents and wind changes would still embed the weed. It is a waste of time trying to fight it - I know what I am saying has been said before, but you just shake your head at some of the idiots out there that call for this banning thing. 5 Quote Link to post Share on other sites
Addem 86 Posted November 19 Share Posted November 19 Do we know yet how anchors will set In it? It may well end up self policing ie won't go there if anchor won't hold. 1 Quote Link to post Share on other sites
Guest 60 Posted November 19 Share Posted November 19 How about a structured approach as in you cant go to barrier for "x' period unless you participate in a mitigation program or some such. Obviously macerating the caulerpa bed with your anchor is a no-no. (not saying that water movement, tides/storms arn't orders of magnitude worse) but surely defined weed free anchoring areas can be instituted meantime. I'd be happy to do some surveying on scuba for the right to visit. ~Cones and Hi-viz vest deployed of course~ If it proliferates as described banning people isn't going to work. Probably, not where you cant anchor, rather small confines where its permitted. Haha! That traffic conetrol costs a disproportion amount of road fixing budget I'm cant see any of above eventuating.

Waa1066 5 Posted November 19 Share Posted November 19 The response by NSW agencies - What is DPI doing? After 15 years of published research and scientific observations in NSW, the behaviour of Caulerpa in the NSW environment is now better understood and we are changing the way we manage it. We believe our efforts will be more effective if we focus on preventing the spread of Caulerpa to unaffected estuaries, rather than on activities that have little effect on established populations. Large outbreaks of Caulerpa are almost impossible to eradicate, require extensive resources and cannot guarantee that Caulerpa will not reoccur so control activities will generally no longer be supported by DPI, unless in exceptional circumstances in a newly affected estuary. We encourage people to “Make clean part of your routine” by checking for Caulerpa when fishing and boating and safely disposing of it. Fishers and boaters will be required to clean their gear and equipment before leaving affected estuaries to minimise the risk of further spread. 3 Quote Link to post Share on other sites

The recent decline in Caulerpa (and native seagrass) in south coast estuaries may be a result of fluctuations in salinity (due to a drought followed by major rainfall events in 2011 and 2012). It is quite possible that small Caulerpa beds may remain in many south coast estuaries. In contrast, Caulerpa abundance in most Sydney estuaries has remained relatively stable over recent years." At least we haven't detected C. Taxifolia yet. Quote Link to post Share on other sites
Waa1066 5 Posted November 19 Share Posted November 19 Yep - agreed it’s about a different variant, but the realisation that eradication isn’t feasible and a “sensible” approach to containment is what I found interesting - how long will we as boaters put up with blanket anchoring/fishing bans ?

ex Elly 186 Posted November 19 Share Posted November 19 On the plus side, that is the best article I have read on what is happening with Caulerpa. Well done, the Herald! Quote Link to post Share on other sites

ex Elly 186 Posted November 20 Share Posted November 20 Caulerpa's spread has some Aotea Great Barrier locals throwing in the towel Some residents want the island closed entirely to visiting boaties while others say the battle is already lost and restrictions are pointless. But with the seaweed continuing to spread and the restrictions - known as Controlled Area Notices, or CANs - due to expire at the end of the month, islanders and biosecurity officials have little time to decide their next steps. A more likely path, depending on the outcome of this week's hui, is to renew and possibly expand the CANs currently in force at Okupu Bay, Tryphena Harbour and Whangaparapara Harbour. It is believed the green menace is primarily spread by anchors. In suitable conditions a piece of seaweed the size of a pinhead can grow to the size of a football field in just three weeks. https://www.rnz.co.nz/news/national/502864/caulerpa-s-spread-has-some-aotea-great-barrier-locals-throwing-in-the-towel 1 Quote Link to post Share on other sites

CarpeDiem 393 Posted Thursday at 12:06 AM Share Posted Thursday at 12:06 AM Gutted. Was hoping to get to Port Fitzroy for our first time this summer. Edit: ) Port Fitzroy Permit Exempt Anchoring Zone: means the area contained within the marine waters of Port Fitzroy, east of a line between Kotuku Point and Mt. Overlook headland of Kaikōura Island /Selwyn Island, and east of a line between the Man of War Passage and Governor Pass. Where is that? Quote Link to post Share on other sites
