Just wondering what the food source for Bass is in Wyaralong.  Are there any Boney Bream or Mouth Almighty?

I fish because the little voices in my head tell me to.

Good point... All this talk about Wyaralong Dam has got me thinking of the food web & wondering what the growth rates of stocked fish will be like. Boney bream often = good growth, but not as good an edge fishery. Eg no bonies in Maroon so it's a good edge / surface fishery. Somerset has bonies but is mostly a thermals / flats fishery.

Always like to know the food web to get an idea of how to target the local fish. Anyone taken any bait traps there to sample what's in there? Or was there a pre-stocking survey done? I'd love to know the results.

Cheers for any info.

Bonies also means fish taste bloody awful.  I reckon that's the main reason impoundment Barra don't taste as good at rust water Barra.

Can say that there has been bass captured and have seen growth rate increase each year.

But being the dam is built on Teviot Brook, which is a tributary of the Logan River there will be common species about.

Me, have seen the following: Green Fish( honestly can't say which M ) bass / euros / Tillies / spangles / gudgeons

But here is some info ripped off the web

Ok

from the web and some studies of the area

5.2 Aquatic Fauna

A total of 40 freshwater fish species have been recorded in the Logan River catchment. This includes approximately 30 native species and none of these species are known to be restricted to the catchment. Most species can broadly be described as common and widespread. Approximately 20 of these species commonly occur in Teviot Brook, of which 10 species tend to numerically dominate the population, with the remaining 10 species accounting for less than 1% of the total numbers of individuals. The dominant species identified include the Eastern Gambusia (an introduced pest), Duboulay’s Rainbow fish, Western Carp Gudgeon and Australian Smelt as the four most abundant fish species.

Some of the fish within the area are thought to be migratory or to take broad scale movements. For example, the Sea Mullet, Australian Bass and Long‐Finned Eel migrate from freshwater to the sea to breed. Australian Smelt and possibly some Gudgeon species move wholly within freshwater (e.g. upstream to spawn). However, large sections of Teviot Brook, particularly the lower sandy reaches, are frequently dry and therefore prevent fish movements.

Logan River Survey info

Introduced species

carp / mosquito fish / goldfish / tilapia / swordtail / platy

Native Species

Long finned eel / fire retail gudgeon / carp gudgeon/  Duboulays rainbowfish / Australian smelt/ Australian bass / eel tailed catfish / spangled perch / sea mullet / striped gudgeon / empire gudgeon / fresh water mullet / flathead gudgeon / olive purchlet / dwarf flathead gudgeon / fly speckled hardhead / pacific blueye / bull rout

Thanks for the info.  I'm guessing it will turn out as a fishery similar to Maroon and Hinze with a good edge/surface bite.  Would make a fine 'toga fishery too.  :-X
