The gold clams aren't edible. mpi says they get full of heavy metals.

they get full of heavy metals....huh and where do THEY come from????

Sewage, kinlieth and veothermal vents under ohakuri.

I understand the risk to infrastructure, but what is the risk to the ecosystem? Genuine question. All of I've read is some vague suggestion that they might compete with unspecified native species.

Seems they form very dense carpets of beds which smother areas otherwise occupied by native aquatics and invertebrates. Thats all I know and I agree its pretty vague.

Pretty much, they aren't mobile and breed asexually and fairly rapidly - and also currently don't have a natural control in NZ. Spat are tiny too... They can totally change the food source and water quality profiles, out competing native shellfish and removing algae and what other native species need through sheer weight of numbers so not ideal...

but wont trout hoover them up? they eat the small freshwater mussels.....

...and we always hearing how filter feeders improve water quality. I don't know what the actual outcome is going to be, doesn't sound like anyone does.

Why not all lakes then? And streams? Rotoiti and tarawera are more at risk given that ski and wake boats use them.

Simply shocking that MPI are not taking action at the source.

I agree that they need to take action at the source. And closing Tarawera is probably a good idea too.
