The heads look too big for triploids. Small heads that go into football shaped bodies is the best sign. Also they are very silver with just a few spots on them and small scales. The meat should be pretty orange also.

The game department said they planted triploids in Tye Lake. I caught several 14 inchers this year but they were very purple in color, the stripe and over a lot of the body. Very strange for triploids. I've caught them before out of the same lake with the usual characteristics

Perhaps they were a different crossbreed that they planted.
