If you are interested, type 'Scallop" into the search area on stuff.co.nz and read the last 12 months or so of articles about the management of the TACC etc.
In a nutshell - Declining fishery needs reduced TAC. Industry suggests a TACC higher than what they harvested the previous year, and MPI agree. The recreational group argue that the proposed take is way above MPI guidelines for sustainable harvest as a % of biomass, but minister signs off Comm sector plan. This season they think they will have to close the fishery.
Just another example of our world leading fisheries management.

As an aside, there is a comment in one the articles where a scientific researcher notes how the cumulative effect of decades of bottom trawling and dredging has flattened the seabed, destroyed all the horse mussels etc and hence destroyed the ability of the seafloor to deal with sediment deposits. Net result is the scallop habitat (and fish habitat I assume) has been destroyed by sediment. How much of the destruction of our inshore fisheries is due to bottom trawling destroying the sea bed and allowing sediment to become established I wonder.

The answer to that mate is A LOT
The dredging of the mussel beds in the firth of thames last century turned the area into a mud floor wasteland. I think quiet steps are being taken by some mussel farmers and processors to try to reintroduce the almost solid mussel bed that once covered the area, but it will be a long and slow process sadly.
It is only my overwhelming natural humility that mars my perfection.

I bet the industry won't be interested in conducting any research on the long term effects of bottom trawling, but given that it might be a significant risk to our long term fisheries and may even be a major contributor to their current depleted state, you might think that MPI should be looking into it at least. Anyone know if they have done any research about this?

My take which would not be to far from the mark as well Dave. Continual
 ploughing of the sea bed has reduced it to a marine desert ..Allows for sediment build up as filter feeders and grasses ,all animal life have been extinguished.
The sediment build up is slow and continual as nothing is mopping it up as had been the case in the past ...Bit like looking at a hills of forest  ...we know what happens when they remove all the trees ...or ploughed up new subdivision's compared to a paddock of green grass .
 
The same would apply to the marine environment ...remove everything the result is easy to spot .
It appears that out of sight is out of mind ..

Good on them but its how they legislate going forward will be of more interest.

So the commercial scallop industry take excess scallops from the biomass each year until the fishery is screwed and then it gets closed to them and the recreational harvesters. Then when it reopens (if not completely wrecked) we will repeat the cycle. Over the long term the commercial sector take each year will average out (excess for years up to collapse, then lower TACC after a rebuild), but the recreational harvest is just slashed by the closures and there is no long term averaging. So not only all those scallops get given to the fishing industry for free in the first place (zero return to the public), but now the public get their traditional right to harvest a feed taken away as well so that the industry can get a faster rebuild of the biomass and start filling their pockets again. What a great system we have.

Would have thought , expected, the "Best fishery management in the world" to have seen this coming. But they didnt.

Can only wonder about other fisheries with below optimum  bio mass.

A very sad state of affairs that need not have happened.

Closed 3 days before opening day.

I think it's good for the scallop fishery but the timing could have been better.

I've got flights to picton Friday morning and back Sunday. Leave booked. Oh well. Fishing it is.

You see the media wagon are at it again. Its not totally closed, only closed in the RED ZONE so god help what little is left in the beds in Golden Bay and Tasman Bay because its going to be open season on them now. 90 submissions out of 159 said total closure but they took option 2 and just closed 7H and the sounds. I wonder some times!!!


There is never a better time to go fishing than now, live the day

My understanding of the fishery down there was they were shown how to seed the beds by the chinesse a few years back, but unfortunately they overseeded them causing them to stunt growth etc... 

 My main concern is that those boats will now head north and hit the areas up here that produce good quantities :(

Don't see why they need a blanket ban as opposed to just a ban on dredging. 

Why penalise divers for the damage that the recreational and commercial dredgers are doing?

My understanding is that it hasnt been closed due to damage caused by dredging, but just overfishing. The 50 scallop rec limit is far to high in my opinion, but I'm coming from a fishery where you are only allowed 10 of the tasty little buggers. 

For what it's worth, we dive for our shellfish, tried dredging once, lost it, just stuck with diving ever since.

I would agree with you ....except....I can't swim or diveCry

Just overfishing. Mind boggles. They didnt see it coming did they.
Why not.???
So instead. Oh well fishery is stuffed,better close it--ho hum.Great but predictable fishery management response.
Pity scallops arnt more aggressive -like sharks. Maybe they will learn and the news headlines will feature more scallop attacks.
Self preservation of scallops.
Proper management would have seen the decline and taken action to stem it long before it got to this.
And even if other factors like parasites or disease were at play same should have applied

Seem they didnt notice either. Not much point protecting them if they are not there anymore.

Was fishing in 7HH area today, 3 small trawlers working in  the area presumably targeting the gurnard at the moment.

So they may not be dredging but how the hell are the scollops and oysters sopost to recover when what little are left after commercial dredging are being run over by bottom trawls?

You make a very valid point Cam.

They dredge the crap out of them ,close the beds ,then smash them up for a bit of add on effect. Bit like carpet bombing.

Totally irresponsible action. Could only happen in N.Z.

Was out off bream tail on Tuesday, we counted 11 scallop boats in about a 2km square area. Never seen that many up here in one confined area like that before and a lot of the boats I have never seen before either. Is this a spin off from the southern beds being closed?
