Hi all!

Been out fishing recently, and have been super lucky to come home with some great blue cod (four)! I didn't really go far out and stayed within inner Waitemata Harbour.

Is this common? I always thought Auckland was just too warm for blue cod so this was surprising to me, especially since this wasn't anywhere flash.  Has anyone come home with such a haul on the regular or was this just pure luck?

Thanks!

I 've caught them from time to time usually too small but have caught a couple over one kg. I'm sure there must be areas that hold them in order to sustain a population because they aren't the kind of fish I expect to be just passing through.

There certainly is and for Auckland it is 30cm. A tad small IMO but legal is legal. One thing and it may be just me but I don't think the blue cod up this way are as tasty as the SI ones. Any thoughts?

I've seen them from time to time while spearfishing but they've all been borderline legal so I've left them alone.

Gut hooked one on a fishhook one day and it was just legal so we ate it - and yes, the SI ones taste better.

IMO SI Butterfish / Greenbone also tastebetter than those around the upper North Island and they also get bigger the further south you go.  (I do like NI Butterfish but the SI ones are a bit nicer)

It makes a nice change, but I do prefer gurnard to cod.
But I have one friend (don't have too many) who totally rates them. Nothing wrong with them at all. We get quite a few on our reefy areas sth of Napier. 33cm is the legal for us. They can get quite big and fight well. Have done well on them on small plastics - but they scoff anything.

We have caught some good sized blue cod in same area and around the same time of year. I was surprised at the time. I think there is a small window where they aren't in competition with snapper for bait.

It's not too warm for them as I've caught lots on reefs in Northland. They just don't get as big imo.

Awesome, thanks for sharing your findings team! I would personally love to see more blue cod around, its such a tasty fish. We prefer them a little smaller to be honest as it fits the steamer a lot better.

This was last weekend, probably the biggest of the lot so far! As for the previous trips out where we got a bunch, the average size was 35cm.

I should also add, nothing too special with the rigs, just a good old ledger and pilchards for bait. I keep the bottom hook quite low to the ground so maybe it helps?

That's a nice fish. I think the low bottom hook definitely helps. We often run one off near the sinker with a smaller hook. It's usually that one that picks up blue cod and gurnard. Again I think it's a competition thing. Also makes sense with where those fish approach the ledger rig.

yeah , thats about right for  round here .....(.Im assuming that is a 2L bottle  ) Smile

 Seriously tho  , I dont think there is much point in taking blue cod at 30cm , even at 33 there is significantly more meat . Being as we give a fair bit away  if there is extra  Im not to hung up on body count  and tend to hang out for something  37-8 + cm.
I wish I was young again .... Id be heaps smarter than this time
