This many predators in a smaller pond is a CHALLENGE... You will have to closely monitor the predators and forage. The biggest thing feeding pellets does is allow you to have more biomass along with the added benefit of faster growth rates. There is however no need to feed if you are willing to be patient, know your biomass levels will be lower and expect slower growth rates.
Keys to making this stocking plan work:
1)Be patient and allow your forage base to establish. (FHM will be gone within a couple years, leaving you just the GSH and BKF.)
2)Provide some shallow areas for the young forage to take cover. This is important is in my opinion the number one reason many smaller ponds cannot support a permanent forage fish population after predator over abundance. Most smaller ponds have very steep sides with limited shallow areas. Usually to prevent aquatic vegetation issues, but to the detriment of natural forage.
3)Provide structure in the deeper areas.
4)Provide spawning areas for the different forage species. Again, research on the forum how GSH and FHM spawn and provide that for them. Keep the FHM spawn structure SHALLOW! Less than 1 foot...
5)Be realistic in your goals for a 1.5 acre pond... This means limited stocking of species. Keep the stockings of the HSB and WE minimal, 10-20 per year max! If your SMB are successful in their spawns, you may have to harvest large numbers of their offspring. This could also be the case with the YP. There are no pellets for them to eat, they will be relying solely on natural forage. There is only so much natural forage a 1.5 acre pond can produce... It may be prudent to even lower the stocking number of SMB down to 50 to allow more forage for the WE and HSB. Keep in mind that the trout will also be feeding on your forage base. Having all these species in a smaller pond can be done, but it is not easy particularly when relying solely on a natural forage base. It seems like you are living on site, so managing the pond will be easier.
If this seems a bit overwhelming, a simpler stocking plan with less species can be recommended... HSB and WE can be added further down the road.
