This is an easy one to address Ithaca... then I have to go back and do some more reading on the dam issue( I aint done with that one yet)
The guy is doing nothing illegal... Hatchery fish are so cheap its rediculious when you buy the quanities that game and fish by your talking less than a cent a piece in most case's....
But here is something to remember... for that one guy catching his limit every day there are people who pay into the system and dont catch one fish in a whole year and or only fish 3 days a year... so people like the guy you mentioned are not draining the system..
However if everyone did it then game and fish would either raise the cost of thier fishing licence or lower the limits on hatchery raised fishing ponds.
Monies from fishing licence's go towards the stock trout programs in most states and so does alot of other moneys either donated or tax'd....
Here in AZ people are encouraged to take as many trout as possible (in the lower elevations) due to the fact they have a very small chance of making it through our summers....
I relize its not the same in Idaho due to the fact that the waters are colder and you get hold overs.....
Now I agree with buzz that hatchery fish taste like crap(you can taste the difference)... I dont keep fish at all unless they are walleye or if I lived back up in washington ...
You have every right to tell him he is abusing the system just like he has every right to telll you to f-off and mind your own business
As long as he is legal nothing can be done....
