 I was recently at 2 well known local fisheries and was surprised to find eggs in my net after releasing the fish.
I thought that these rainbows were triploids ( i think this is the word ) and so why would they have eggs?
Do they still produce eggs but are infertile ?

The process is supposed to make them sexless, but like everything else in life it's never 100% sucessfull. The chance there is a fertile male to fertilise the eggs is slim. Also the eggs need a certain type of gravel and generally running water to keep them at a constant temperature. So in short the chance of them making babies is slim.

Has happened though?

Yes you are right it has happened, but nowhere has it been able to create a viable self sustaining population (Brookies are adifferent matter)

Yup know a couple of wild lochs way up in the hills with nothing but brookies in them, and another with a good mix of brookies and browns.
