Many but not all the FinF YP are pellet trained. I know the source and those YP are from very good genetic domesticated stock and raised well. Their offspring should produce good quality YP. At the 2"-4" size a high percentage might not resume eating pellets. Better success would be with the 4"-6" or 6"-8" sizes if you rebuy more. Not a lot of Fenders YP are pellet trained; pretty good stock but mostly pond raised in house on natural foods.
Lack of seeing very many YP in your traps indicates a relatively low density of the YOY perch. As an example late this fall (Sep29-Oct 21) in 4 trapping sessions using 3 traps in 0.7ac, I caught 498 YOY YP (3"-6"). Traps were either 1/4" or 1/2" mesh homemade traps; most were caught in 1/4". 161 were caged and pellet trained and the rest were given away to a neighbor.
