Bugger me another species thats unwanted is now in the Waikato river.
Asian clams'
Initial checks have found the freshwater gold clam present over a 45-kilometre stretch of the Waikato River, from 1.5km upstream of Bob’s Landing, just upstream of Lake Karāpiro, and downriver to Hamilton.
Mr Anderson says the plan now is to search further, both within the Waikato River and in other rivers and lakes that are linked through human activity.

Currently, MNZ's opinion is that ANY $ changing hands is then commercial, profit or not. We don't wish to test it in court. Plus, using a member's boat for a learn to sail course most likely invalidates their insurance. The idea, in our case, is not profit making, but for the club and the promotion of safe sailing ...
It will be discussed further between MNZ and YNZ... and our club.
Be all good until theres a mishap.

recieved today as in a f/b advert from ayba
FUNDING WILL DICTATE OUR ACTIONSThis is crunch week for the Auckland Yachting & Boating Association who are striving on your behalf to protect these facilities!We have to make a decision by Friday whether we continue fighting on your behalf for:A. THE RETENTION OF THE HARD STAND & HAULOUT AREA AT OKAHU BAY:• We have already overspent our legal budget.• We cannot continue without the funds!• Once lost there can be no replacement! -

Umm the current dumping zone is just behind the Barrier near the old munitions dumping area -not way past Cuvier like what was done in the eighties and nineties, this is used by Pine Harbour , Westypark and others from around Auckland-which is of course why the Barrier residents and Iwi were so up in arms about it being granted permission.
Yes that why I emailed Eugenie Sage,she was Minister at the time for eviroment?Got a wishy washy reply as I said with fan worm being in Auckland and dumping so close to barrier,wont be long before fan worm is established.

Haha been here since 2021 but no action till 2022
https://niwa.co.nz/news/marine-invader-caulerpa-triggers-biosecurity-response
Two new species of non-indigenous algae were discovered in mid-2021, identified by NIWA researchers as Caulerpa brachypus and Caulerpa parvifolia.
New Zealand has some native species of Caulerpa but the two species identified in 2021 showed similar characteristics to the highly invasive Caulerpa taxifolia that has been problematic overseas. Caulerpa taxifolia has been listed as a Notifiable Species under New Zealand’s Biosecurity Act since 2001.
The two new species of Caulerpa were found in a variety of habitats and depths near Aotea. They covered large areas of seafloor and appeared to spread quickly.
Both species were given the status of Unwanted Organisms under the Biosecurity Act in September 2021.

Nothing new,Australia has had it since 2015 or been monorting it since 2015?
https://digital.library.adelaide.edu.au/dspace/handle/2440/104681
Populations of the green marine macroalgae Caulerpa taxifolia and Caulerpa cylindracea have invaded and spread throughout Mediterranean after they were introduced from Australia. In Australia, these tropical to subtropical species have established invasive populations in New South Wales, South Australia, and most recently, for C. cylindracea, in Victoria. Significant efforts have been made to elucidate the invasion history and geographic source locations of Mediterranean populations. The same effort has been lacking in Australia. Both species have provided challenges for molecular ecologists because of their predominantly clonal reproduction and low genetic variation within invasive populations in the case of C. taxifolia, and very high intra-individual genetic variation in C. cylindracea.
. I have also shown that the response of native and invasive Caulerpa spp. to climate change scenarios indicates that invasive populations of Caulerpa may become more abundant and continue to expand their invasive range in the future. I also identify the limitations of this body of work and the issues encountered in the program of research, and discuss future research possibilities for invasive Caulerpa species.

Very possible it came from the viaduct. Remember they dredge it and the dumpings were off cuvier island
So may of been here longer than we think.

https://www.cruisemapper.com/ports/great-barrier-island-nz-port-5496
Great Barrier Island is located in outer Hauraki Gulf, New Zealand, approx 100 km (60 mi) northeast of Auckland. The Island covers a total area of 285 km2 (110 mi2), ranking it New Zealand's 6th-largest. Its highest elevation point (Mt Hobson) is 621 m (2037 ft) above sea level.
Cruise ships to Great Barrier Island dock/anchor at Tryphena - a port town on the southwestern coast.
So there would be a possibilty this is where it came from pre 2022?

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
Show me a canal/river in the waikato region without koi carp. They everywhere. Bloody hard to catch so have taken to dragging a old tennis net and getting plenty.They stnk as we put them through a mincer for berley.

Apart from Facebook MPI or from this site.How would I know there is "caulerpa"
NO signs at ramps that I use,in fact wandering around "Westhaven" no signs on gates to marinas
NO mention on fishing shows that Tryphena and parts of the Mercs are no anchoring.
So not a major problem as not out in front of the public on TV. Dont buy the herald or any newspaper

Plenty of options around in the fish finder range,but straight depth/speed? Have a garmin striker 4, shows depth/speed/gps can set tracks /way points etc hardy little unit for under $350 with chirp transducer.

Very little mention of the once proud Royal Akarana Yacht club , still thats the way they chose to run it into the ground, perhaps the squadron should take on the emmies -store them in the Vic building and bury Akkers .
The Squady had the "m" before the aks took them over,not sure what the reason was.. Use to race Saturday 1.00pm with a fleet of 10 most of the time.
Might of had something to do with squady new premises and "Ms" couldnt be arsed getting out of wet gear.

Marine farms in the Firth,
They are still on the cards "Otto" and will be a reality soon,if you are talking about fish pens
Can someone please explain why there is a big launch still up on the landing and where has the RAYC gone to. Was down there today and all I saw was a building with big signage saying Marine centre.

The Auckland council is broke,no $$,looking at rate hike of 22%
Yes they are responsible for bio security and seafloor/fauna/even stock out to the 10 mile limit but you stump up with $5 mill starting point and have a go.
I can just see YNZ saying we need to fight this and need $100k levy from every club and $20k from each boat owner. Give a page doesnt work as they have a page going and what was the last figure $9k??
I keep reverting back too 2013 where they outlined the plans for the okahu bay area.It was all for all to see but like so many we sat on our hands and said"this wont affect me so I will do nothing" guess what,no objection so now to put our planes in place.
Ayba/ynz missed the boat.

trying not to be negative. But with recent events(weather since January)Think council has more to worry about the a few vessels that use the facility. When I say a few, last few yrs never saw it packed out. Remember when Westhaven had the slipway by the bridge? Use to be given the hurry up to get back as others waiting.
Due too rising costs,not just haulout but antifoul etc have joined the trailer brigade,Havent used for 4 weeks so if I had a moored vessel probaly be unused too,weather and commitments

That's disappointing. But not particularly surprising....
You cant better city hall,ever protested a race committee and won!
When Legasea/option4 went before the supreme court over recreational Kahawai , cost roughly 1 mill,3 court appreances ,a win ,a lose and might say a draw,the outcome was.The minister shall provide catch rates ahead of commercial when species become low in biomass. (rough translation) so expect to spend more than that to bet council

All of this nonsense is why the ferries can't get crews. - plus the low pay of course..
And that is why so many Indian taxi drivers due to the fact they need to complete to NZ standards. The heart lungs etc are in the same place as theirs so whats the problem. we have a pharmacist driving due to not able to afford to NZ course.
Its a crooked system. Time served in NZ or overseas should count.

Fan Worms are left unchecked and they deplete a nutrient required for Snapper and Kahawai to breed. Is this a good or bad thing? Well, it depends on your perspective. But for Snapper and Kahawai, it's undoubtedly a negative outcome.
From What niwa has posted,seem to be a water filter but can take nutrients away from oysters/mussels,no mention of fish.
With warmer tempertures,more shipping its only a uestion of time before more deadly pests arrive,as someone pointed out .The pacific oyster which has overtaken our rock oyster,now an industry.
Caulerpa now in BOI

So it can disperse in currents.Now thats a good idea
