If you're pellet feeding, the need for any forage fish isn't there. Now if you aren't planning on feeding, then the addition of both FHM and GSH may be prudent. Keep in mind that GSH will compete directly for food sources with smaller trout and they will reach larger sizes that the trout may not be able to control. You may end up with a stock pile of larger 7"+ GSH and trout not large enough to feed on them. This would be particularly true in a pond with all or most brook and rainbow trout. If tiger trout or brown trout are stocked, they may be more capable to keeping the GSH in check.
