Every thread I've read on this forum about feeding has fascinated me, mainly because my observations have been so different to what most of you report. The BGs, YP, and GSF in my pond will not eat any fish pellets. The BGs have mouthed both AM 600 and Skretting feed but then reject it. They no longer will even approach pellets. However, the RBT and BRNT jump all over floating pellets. The several GC do, too.
What these trout and carp will NOT do is take a pellet that starts to sink. I believe this is a result of my having caught and released several of the trout and a few of the carp. I haven't caught all the individuals of each species; the uncaught ones appear to have learned to avoid sinking pellets. What I was doing was wedging a pellet in the bend of an appropriate sized hook. The weight of the hook caused the pellet to sink. This worked for a while but Not No More!
These creatures that hold nearly endless fascination for many of us surely can learn how not to get into trouble, can't they?!
