no need to worry about off-topic. this will go where it will go. it's not like a herp related thread that can go crazy real quick-like.
from what i have always heard, tigers are sterile. i will point out that nature always finds a way.
who knows, maybe "us" messing with it for long enough helped set up "plan B". God has his ways.
That is correct. Nature finds a way. There is a small 60 acre lake not far from my house. They stocked musky there thirty years ago and then quit. They werent supposed to be able to spawn either but guess what, you can go catch one there today! Mules are hybrids too, but I know of instances where they have still reproduced. In regard to the origional post, where I fish at Cave Run Lake, they have a 2 fish limit with a 37 inch minimum size.
As far as survival after release, the rates are pretty high. A friend on mine and guide on cave Run also guides for tigers up north and he photographs them all so he has photo IDs. He has caught many Tigers multiple times. Their patterning is so unique from fish to fish that it is hard to mistake one for another. He has even reached the point of naming various fish that he has caught over the years.
