Yes that can happen both with and without Lepomis (BG ,PS , GSF etc).

It is called carrying capacity (sometimes standing stock)and exists for all waters. There are hundreds if not thousands of studies on the topic and it is discussed at this thread from the archives.

In an unpopulated water most species will ASAP try to fill it with their kind. That time period varies somewhat but from comments here it is , depending on species , from 18-24 mths in the south to 2 - 3.5 yrs up north. From that point on no matter the species you are managing the division of the % and sizes of the fish to keep ( balance or unbalance)or meet your goals. It is one of the most basic principals of fisheries mgt.
