I know it isn't anything new and I've seen the graphs for Silver Perch and Trout on the forum before.
If anyone missed it here's a link to a page that gives an estimated weight for the length of several common species. Including Golden perch, Murray Cod, Bass and others.

I mentioned it in another post but thought that not everyone would see it there so decided to start a thread so it is easier to find.

And for the pedants out there I do realise that you'd use a rule, not a ruler...

Does that mean I can work out my weight by knowing my height?

I'm not over weight. I'm just not tall enough.

Call me exceptionally pedantic, but I'd use scales!...

As EB and Arbe pointed out, when harvesting last years batch of Trout I had all kinds of shapes and sizes, from large slender ones, to large slender ones but with fat bulgy guts, and even a short stumpy one (that I had unimaginatively nicknamed Stumpy) that appeared to have almost no peduncle, much in the same way rugby players have no neck, and was very "stocky"... almost like a bear can with fins. He was a fair bit shorter than the average length, but his weight was on par.

Cultured fish are sheltered from the selective pressures that reduce variance.
