while chattin to some mates this arvo and they are fisho's as well, and some have been around for a while and know a thing or 2, 1 lad was telling me about a time long ago in the tweed river all the fish died due to lack of oxygen, b cos of the amount of fish, hard to imagine, but another fella who doesn't BS was sayin he had seen the council on the water front with front end loaders and loading up semi's of dead fish, and the amount of sharks out the front, but they wouldn't come into the river? he doesn't know why to this day, but gave the ol shark credit for knowing something! how times have changed, and i have no reason to doubt the word of the 2nd bloke at all. those would have been the days ay.

I don't doubt a fish kill caused by lack of disolved oxygen but the lack of disolved oxygen being caused by too many fish is not possible.

There are too many factors that play a much bigger role in determining oxygen levels. i.e. alagal blooms, pH, temperature, disolved solids etc.
