There are both in the lower Illinois river, but I'd have to say these were definitely 'stocked'  fish,   about the dumbest trout I've ever seen... : )   But it could've just been they were tired of seeing 'rattle traps on 12# line" thrown at them ???   Took a little less than an hour with ultra light spinning gear, 2# leader and a 3"  "Lucky Lady" on a #12 long shank wire hook,  had 3 pounding it(spitting it) out at the same time at one point....  they should hand out heart meds with the trout tag.....  
It was  my first time here
