Title: What Gudgeon is this???
Post by: Bracey on May 04, 2011, 05:38:38 PM

G'day all,

I have had a few additions to the tank including about 6 small Redclaw that Feral so kindly got for me in which I put in over the weekend. Out of the 6 I think I only have about 4, one taken by a Bass and another by the Yabbie.

We have a small creek that runs past our place that is a tributary of Mellum Ck. My young fella was down there with his mate the other day setting some traps and they managed to catch this Gudgeon that is about 75mm long. So far it has avoided the clutches of the Yabbie once and the Bass along with the Archer fish. If the Barra was still in there I reckon it would have been long gone.

I have attached a few pictures of this Gudgeon in the hope to find out exactly what species it is?

Thanks in advance!

Cheers Dave

Possibly a Purple Spot Gudgen , just a little washed out from the stress of the other predators in the tank . Northbrook creek that runs into Billies bay at Wivenhoe is full of them.

Cheers,
Dave.

Since my surname is Gudgeon you would reckon I would know........ but I've got no idea   8) 8) 8)

I was gonna say purple spotted but they don't quite look like that I don't think.

cheers

I don't know that one........

Wait for someone like Elops or Jim Tait & they'll tell you name, taxonomy, heck they'll brobably tell you the sex & age of it.....

I'd like to know as well.

Cheers,

Thanks fella's,

I tried registering on an online native fish forum Fitzy to find the answer but due to spamming they have ceased registering new members since January, I did see that Jim was a member there and I know that Steve is quite knowledgable too when it comes to identifying these smaller species.

Keen to find out!

Dave,

I think Drjfly is on the money, looks like a Striped Gudgeon Gobiomorphus australis, we have them in our creek as well (part of the Richmond catchment) - the only other one that comes close to it is the Cox's Gudgeon but cheek and lateral striping is different. If you put striped gudgeon in Google and hit images - you'll see it. They get big enought to take worm baits in our creek ~15cm

Regards - Jim

Yep I'm pretty convinced after Drfly and Jim have comented on the post as the Gudgeon being a Stirped Gudgeon. I didn't know that they grew that long though.

Thanks Dave

Yes it is G. australis grow quite large 20 cm max. They are amphidromous with the larvae drifting downstream into brackish water where they spend the early part of their lifecycle, then travel back upstream. One of our native species whose range has been reduced by stream barriers.

cheers
Steve.

Thanks for the info Steve, It would be great if it survives to be as long as 20cm. They are a pretty attractive fish in my opinion with plenty of character.
