Well heck . The buggers are an aquarium item and the young start life as larvae , those would be hard to detect in a fish shipment .

I have a hunch it maybe to linked to global immigration and someone in Hamilton or Cambridge hankering for some downhome fried clams

We are under assault . Looks like the horse has truly bolted on this one .

Anywhere could’ve been the vector not just Auckland . If for example if it was off an anchor the boat could’ve have been heading north , stopped at mercs first then Barrier . That puts every harbour and domesticated inlet south and inshore of the mercs in the realm of possibility

It could probably survive a trip down the drain from east coast road to the nearest beach ? How would you empty 100+ litre saltwater aquarium ?
it could be well established in a corner of some murky harbour were no one dives and it doesn’t get enough wave movement to get washed up

Can I just point out this is the best debate on crew org in quite some time .

Love the stuff ! I’ve saved a bit of coin on silicone since I got a roll .

I did hear about that. And I am not disputing the theory is possible, rather it just seems a bit of a stretch.
On the scale of strange, I would consider spreading fish to create a fishery less strange than establishing a useless strain of Caulerpa at the Barrier.
If some NZ resident comes forward with an eradication solution that they have been working on since before the outbreak was detected then I might consider that a little suss
Yeah well I’ve been stockpiling cyclone ruined pvc wedding marquees and I’m on the hunt for some cheap chlorine , just need some dive gear and I’m in business

Aquarium Caulerpa (Caulerpa taxifolia) has not been detected anywhere in New Zealand.
The Caulerpa at the Barrier is Caulerpa brachypus and Caulerpa parvifolia.
To suggest that someone knowingly and purposefully imported two types of Caulerpa that are not widely used in aquariums and then chose Great Barrier as a place to accidentally release it, seems a little bit far fetched.
Stranger sh*t has happened . Did you hear about the bloke that traveled nz releasing coarse fish for a lark ? Started out wanting a coarse fishery but it got a bit sinister towards the end it seems .

Having a punt at how it may have got there . looking at how much got displaced at barrier during cyclone Gabrielle and seeing the drift path of 888 from Fitzroy it may have just got there on the wind and currents .
Going back to the 888 drift path , if some of the stuff did get displaced out of Fitzroy it could be all up the coast already .

I fear that most people’s first knowledge of it will be on 27th of December at red head or Albert passage . Good chance you will get turned away from entering the inner bay . Hell , even whangamumu and whangaruru could be affected by then .

Caulerpa sounds like it could be a significant threat but thus far my only real education on the subject has been my google searches, that's not good enough. Which agency is meant to educate and raise awareness of Caulerpa, because they are doing a pretty poor job. Most boaties are environmentally sensitive enough to take real responsibility regardless of the rules. Also it appear that fanworm program suffers the same problems, but these agencies are looking to lay blame on yachties for transporting it around but are ok with Auckland marinas having no requirement to control it. Furthermore the closure of free cleaning facilities like tidal grids, affordable haulouts etc are in total contradiction to the aim of clean boats and it makes me wonder if there is any serious leadership at all?
If a spotted bohemian gadfly ever turns up in Whangarei town basin there will be MPI folks there within hours installing pheromone traps all around the nearby suburbs . 1 year later with caulerpa ?
-
But seriously . Someone needs to talk to the Americans yesterday about their eradication techniques . Rather than piss around with think tanks with boaties . The horse may have bolted for barrier and the mercs but it could possibly be kept under control if action is taken very soon . I imagine it would be a game of whack-a-mole but the alternative is rampant spread whilst hang wringing think tanks are taking place .

What’s the chance of finding some 888 wreckage nearby ?

Just seems weird that everyone just recrosses the line when boats still I would have thought staying clear by rounding outside the odm would have benn the cool thing to do.... Anyway just thought there was a rule at some stage
Maybe it’s now the epitome of cool to sail straight back into the slower boats ?

Doesn’t seem like you will need a fancy phone to use the voLTE network ? iPhone 6 onwards are compatible as long as it has the latest OS .
it’s a long way off though , SMS only by the end of 2024 and data not available until sometime in 2025 . It will simplify things on board I guess if you want internet . No need for gadgets and gizmos with antennas .

Given that it appears that chlorine is considered for eradication of unwanted sea flora, "they" must realise that if used it will kill all the things that TBT apparently used to kill so well, that we are now no longer allowed to use it?
Quite true . You are probably the most qualified person on the forum regarding aquatic flora and fauna , do you think Caulerpa is or could be a problem ?
-
Sounds straightforward ….PVC tarps , chlorine , some good underwater operators and approval from wherever it needs to come from and soon not next year when it will cost 100s instead of 10s of milliwongas

Howdy.... anyone had any real world experience with one of these?
need to replace my speedo (the old navman s100 finally gave up).
All I've got is a raymarine a series MFD downstairs with no network at all at the moment. Was thinking of adding a raymarine i70, but would also need to build a network to add it so ends up being reasonably cost neutral.
I will add a speed transducer in time as well (probably the airmar dst810 with the wireless capability) but not keen yet as the boat has only recently been out of the water (typical)
the ultrasonic wind sensor also looks like an interesting addition, but seems to be mixed views on those.
any thoughts/advice?
thanks
You could get a Velocitek prostart or novasail . Not sure if wait times are still an issue for the Vakaros ?
-
Not Delaware but relevant . Eradication techniques are further down the page . https://www.fisheries.noaa.gov/west-coast/habitat-conservation/caulerpa-species-west-coast
Seems quite involved but surely no more expensive than holding meetings , hiring consultants or underwater companies to check boats .
100% they know the information above that took me 2 minutes to find and any other methods of eradication , so why feck around and find out ?

Hi Addem, I look after this newsletter. I also have a long history going back around 20 years with Crew.org.nz (I founded it!) although I'm doing less (actually, zero) sailing these days (kids, work) and just drop in sometimes to see what's up. Firstly, the 'Clean Below?' newsletter goes widely to a list of subscribers. I promise you are only on there because you have signed up, or someone has signed you up. Maybe at a boat show? You can definitely unsubscribe at any time - just use the link on the bottom of the email or reply to the email and we'll sort it for you. If anyone reading this would like to get the newsletters, just sign up on the website www.marinepests.nz/news
We hope that many of you 'Crew.org.nz-ers' will come along to the webinars. Marine biosecurity is a complex field with a huge range of considerations and TON/TOS have arranged these webinars to open up discussion, build understanding on both sides, and continuously to reflect this in its stories and newsletters..

Hi Zoe thanks for letting us know you are the newsletter editor .
The number one tool for boat owners to combat marine pests is effective antifoul . There has been mention on clean below good to go about Selektope . Hempel paints have a Selektope containing antifoul available offshore . I have emailed the Hempel distributor but they don’t reply . We need to get proven effective antifouls here pronto , the soft coprous oxide paints just don’t cut the mustard and aren’t great for the seafloor either . Pressure needs to be applied to whichever Govt department approves antifouls to get these emerging paints here ASAP .
