Further to Yoshis query to Ron regarding the age of bream I dug this old image out.
You would presume as per Snapper the fish grow slower in colder water than warmer water so it would be a general sizing.
The discussion of the 32cm fish is older than we thought

Yes thanks to Ron for sharing his knowledge and the committee for organising the evening. Lots learnt

Re: The age of Bream
That is an interesting chart Neil - I hope I can print it out clearly. I know a couple of small systems where the fish are not fished much but are numerous and all small and similar sized systems with only a few fish but some quite large ones making me think that the growth may well be tied to food availability. Would be worth catching up with some of the researchers and have a chat with them. Are bream aged by the growth rings on their scales? If so I may need to get a microscope!

Apparently the diet of Swan bream is 60% mussels. It appears under observation only the bigger fish in at least the 250mm+ range can crush the mussels. The biggest I have seen in another boat went 52 cm. Fat fish
The Swan river mouth used to be just a rockbar.
When you go to other rivers the mussels are less prominent. Augusta appears almost devoid of a reliable food source after the 1982 flood the river was altered.
Southern rivers below Bunbury have little prawn populations.
Interesting about the food competition. In the UK the female Northern Pike keeps Redfin perch numbers under control. When the big female Pike is killed in a pond the male Pike numbers explode as do the Redfin.
I believe now Trout fisheries are stocked in the UK to eat dying trout & animals to keep the water clear.
The balance is lost.
Murray cod must be Australias balance keeper.

Re: The age of Bream
Hello guys
It is interesting.
Most of big bream that I have caught had a set of stubby mussel crushing teeth. However, I have come across a few large ones with sharp teeth looked to be more suited to kill other fish.
May be they have adapted to different food sources in a given environment. If Charles R Darwin was a fish biologist, he could have reached the theory of evolution by studying shapes of bream's teeth in different water systems.
See you

Yosuke,
had a squizz at your blog! very interesting read!
Great Stuff!

Were the sharp teef upstream Yosuke?
It must be the mussels that make their lips go blue? Smashing your face against a pylon all the time would do that.
We need to take pictures of teeth so we can go Darwinian on the Butcheri
I never catch anything big enough to see teeth so any other photos would be appreciated..

Re: The age of Bream
Read somewhere that a study was done that showed swan river Bream grow more quickly than in other systems- dunno how much faster though.
Funny how they get to 20cm in a couple of years then take 20 years to go the extra 20cm hey?
