In my area we have had thus far a pretty mild winter. In fact the since Christmas the temps have hovered between 60-75 degrees and I am still pellet feeding. I throw out a little and see how they react...some days they eat more than others. I actually started catching some of my F-1's about a week ago just to see if they would take a lure. Caught so many I lost count. Alot of the F-1's are in the 10"-12" length which is amazing to me since they were introduced to my pond at about 2" long in June '05. What really amazed me is how fat they are. Can't wait till the upcoming summer to see how big they have gotten.
