Rad, yes I do mean 20,000. Was not real wise when originally stocking the PB as they went in before the Tilapia so played a little catch up...was not a Pond Boss meister at that time!
I have several other species for a forage base and a few other predators. On the first release of 50 (4) inch Peacock Bass only a few survived, thanks to Mr. Snakehead. On the second and third releases (50 PB each), I released 1000 similar sized Tilapia and several subsequent stockings of 1000 fish of varying sizes to cut down predation and add forage for the Peacocks. It has seemed to work well. All of the Tilapia were unsexed. I do not see swarms of the them... so far but will know more of how it is going when I return home next week.
*You know the Tilapia was in aquaculture in Israel 2,000 years ago, some think that they might be the fish that fed the masses! :rolleyes:
