What do you think is in the pond now - species and sizes? If you have big GSF then probably there is another predator in there or the GSF would be small.

If you have adult LMB then you want 5 inch CNBG and RES. Numbers are ok. On the CC I would cut that back to 50 so they will grow and not crowd the pond. As you catch some then add some more.

I would not stock LMB until I knew what was there now.
