This looks really interesting. Groups on Waiheke are set up to harvest kina by using volunteer snorkellers and divers in Enclosure Bay. The Iwi distribute the kina as a toanga food source, and the idea is to see how fast the kelp forests regenerate when they aren't being nailed by kina. I've always thought for every snapper a fisho catches, they should go and catch 50 kina, and well, crayfish. You just shouldn't catch crayfish anymore. It is amazing how few people know what a kina barren is, and how the whole ecosystem collapses when there is no seaweed for the nursery fish. It all starts with taking too many snapper... www.waihekedive.com/products/kelp-gardeners?fbclid=IwAR3b8XXnbEREdupvEDhsDwaBIj3Kd0Y9JjeaJmnbr3vd3IccVFwZI9M_EyY |

Rather than addressing the symptom (kina barren) I’d rather address the cause (snapper overfishing).
Why aren’t we seeing the same bans as for scallops?

Because 3/4's of NZ think it is there god given right to go fishing. And snapper is the easiest thing to catch. So they catch snapper. and lots of it. Remember when they reviewed Snapper1 area, and proposed a 2 fish bag limit? The recreational industry is huge. Just look at how many fizz boats are parked in driveways around your neighbourhood. I'm surprised there isn't a total ban on taking crayfish. They are functionally extinct in the Gulf. I like to focus on what I can do though. I can snorkel and / or scuba, and smash up as many kina as I can - max 50 of course, to comply with MPI rules ;-) I actually caught a snapper big enough to eat, way back when the weather was good and we were actually cruising on our boat (remember that concept?) So I feel it is my duty to go and smash up some kina to balance the ledger for the snapper I took. |

Looks like a worthwhile project, could be done in many other locations.
How do you remove the Kina to avoid getting spiked?

But most of the dive shops are out at the moment "covid disrupted supply chains". I got a paua knife, so I can just smash them up. I'm not sure if its politically correct to just smash them up, but in the barrens they are all very skinny because they have eaten all of the food. I'm assuming not much of a toanga spicies when there is nothing inside them. Bostique Bay was shocking for them actually. Went snorkelling at low tide with the kids, the place was just thick with kina. |

I have a Panga knife on board for chopping up coconuts (and repelling boarders  ), I guess I could use that to lift them off into a bag. I would not have an issue smashing them up, bit of food for the local fish population |

What are the noisiest living creature in the Hauraki Gulf? Snotty screaming kids, maggoted yachties and conversations about how wonderful Jacinda is are excluded?

We have slowly removed the bigger fish that can smash kina,in return the kina have destroyed the kelp and the fry,small fish,have lost their habit of protection from bigger fish.
But those the grew up around the devonport shoreline,during the 60/70s would of seen the kelp/seaweed etc from the naval base to northhead at low tide or around the wharves,its all gone and not the kina but the pollution being dumped in to the harbour so we are part of the problem too.

I was never a fan of kelp as I remember it plaguing many favourite anchorages around the UK coastline and our basic 1980s anchors could never cope with it eg CQR, Danforth etc.
But I get the ecological importance.
I wonder if there is any useful link here between kelp’s role in the oceans and the use of seaweed on land to stop cows farting?

Im trialing a seaweed based fertiliser. Stinks real bad but the grass seems to like it, there is a vert distinct line where sprayed meets not sprayed.
Mostly seaweed but with another not so secret 11 herbs n spices. All natural, which is what we're after.
I believe the weed is harvested on the top 1/2 of the Nth Island west coast.

Her outdoors makes her own brew. Collects the fine weed that washes up in the beach, across the road, puts it in buckets and dilutes it with water then let's it ferment for a week. Works a treat, but does stink. There's tonnes of it on the beach. If I had a digger with a bucket and some big tanks I would be rolling in it. .. but I know some Desmond Dogood would dob me in for something. |

My missus makes seaweed tea. It is great for the garden. I believe the key elements are iodine and some other trace minerals seaweed is high in.
To get brownie points I go and collect bags of seaweed for her. Should be a good haul after this storm blows through.

Get the kids a worm farm. Add the worm wee to the seaweed tea and then watch the garden go off.
Just ordered 2 x 150lt spray units, ones I can drop on the back of the quad. One to kill and one to feed. I hope they turn up in 2 different colours or I see the potential for a large disaster.

Oh, we already have worm farms.
And bokashi (spelling), it is for composting meat scraps. That makes the garden grown gangbusters. Doesn't smell to fresh when digging it in, but you get that on big jobs.
We put very very little out in rubbish these days. Recycling usually once a month. Everything else into the garden. Even carboard boxes that shit gets delivered in get composted, or used as mulch.
