Hi, Just wondering if you can give me a positive I.D. on this fish?
I have been told it could be a Silver Perch and another person reckons it is a Leathery Grunter :-\
Cheers
Pilly

pretty sure its not a silver but could be wrong if its from darker waters ive only caught smaller ones
Steve
-
My call is a silver
-
Yeah, I'm calling it a Silver Perch (Bidyanus bidyanus)
-
Heres a photo of a small silver perch a mate caught if its any help at all. I reckon after looking at this id say it is a silver
-
Thanks Guys,
It did come from a paperbark lined creek that had a tanin stain to the water.
Cheers

G'Day Pilly,If its in the catchment where you live ie the greater Fitzroy, Leathery Grunter are native to that system where Silver Perch are not. However there's been alot of silver stocked throughout the system over the years.
It looks like a silver, too big/fat for most Leatheries I've seen.
Go up the lake near you & run a fish finder near the wall, you'll see absolutely tonnes of leathery grunter there. I guess the best way to know is in the cooking / eating. If you could it eat it, its a Silver, if it was like trying to eat a rubber boot, it was a leathery.
A super long shot it, it could be a Barcoo but none of those should have been stocked where I think you're fishing, but there's been some cowboy hatcheries over the years who would sell anyone anything for a buck.

No doubt: Silver Perch.
Fat bastard!

I couldn't tell ya what fish it is but I want to know what lure that is hanging out it's mouth ;)
Cheers

Hi Sel,
It is one of my homemade lures mate. It is a new design I came up with and it caught me Toga, Silvers, Fork tailed Catties, and Sooties on the first trip it did. I am really happy with it, it has a really different action to other lures I have made. I would be interested to hear your thoughts.
Regards

It is a reasonable size one whatever it is. I thought Silvers tended to look a bit like a yella when they get a bit bigger. Profile that is, small head running up to a big fat body.
I have seen some massive silvers in a place you would never expect them(Disabled Kids fishing clinics put on by the PRFMA). They all seemed to have that funny shape.
This pic sort of shows what I mean.... http://www.sunfishsouthmoreton.com.au/files/2kg-silver-perch.jpg

Fat dam fish in the Botanic Gardens compared to a fit river fish. They're a bit like Bass and Yella's that fat up in still water
-
I recon its a leathery grunter. But its hard to pick the diff between barcoo, welsh's, silver, leathery and several other grunters. Can the grunters cross breed?
-
Hello everyone, just newly joined the site, name's Mick.
I don't reckon pilly's fish is a silver, bushwacker's definately is.
The eyes are the wrong colour to be a silver.
-
Just checked some old pics. The silvers I've caught have the dorsel fin joined to the softer rear fin. Pilly's seems to be separate. I don't know enough about Grunters to make a call though.
-
Still suspecting a grunter of some sorts myself even tho i have never seen one in person, the colour doesnt seem a stained just natural ... still got me guessing .... :o
-
It is Scortum hillii a Leathery Grunter. Spine and soft ray counts are inconclusive, the ID keys visible are the the two distinct preopercles the shape of the pectoral fin, second dorsal fin, eye position and colour.
The colour of the fish gives it another regional common name Greenhide Jack.
Can Grunter crossbreed ? yes they can, one of the reasons for the regulation prohibiting translocation of fish outside their natural range.
With Terapontids (grunters ) this can occur among members of the same Genus ie. Silver Perch Bidyanus bidyanus X Welchs Grunter Bidyanus welchi.
Barcoo Grunter Scortum barcoo X Leathery Grunter Scortum hillii.

Had to use the references Fitz and had some expert help :-[

Thanks for all the help in identifying this fish. :youbeauty

A Scrotum Hilli, I guess that's where the "leathery" part comes from. Now we know.
-
What system was it caught in? Doesn't look like a silver to me, as stated eye colour and position is wrong and mouth seems to be terminal where silvers tend to be a bit more ventral - also appears to have lateral stripe below eye typical of Scortum spp - I'd call it for S. parviceps (small headed grunter) if near Burdekin basin or S. hilli (Leathery Grunter) if near Fitzroy - regards Jim
-
Opps! only looked at first page Elops already had it sorted!
-
At least we know your right Jim :)

My money would be on S. hillii
Terapontid ID can be very difficult.
The pic is a good example, can anybody ID these two ?
cheers

Top is a Silver Perch Bidyanus bidyanus
Bottom is a Welchs Grunter Bidyanus welchi
Would have thought they were both Silvers myself.
