Thoughts on the term "green trout"........

It's an interesting term. As a kid, growing up in south La, but having parents from north La (and a camp up here), I thought the term was funny, and couldn't imagine how it came to be.

I now understand, as here's a text I got from a buddy a couple of days ago.....

"_____ and them ripped'em at the wall about a week or so ago. Had 23 specks over 3.0 pounds, and 15 or so smaller fish. Couple of reds too, and a green trout that weighed over 4."

If you grew up fishing Lake Catherine or Bayou Beinvenue, and caught a "green" fish every now and again, what else WOULD you call him but a "green trout".

How many folks here call them that regularly, and where did you learn to fish?

1. I do not call them that regularly.
2. I learned to fish on Black Lake outside of Campti, LA.
