That's a lot of fish you've removed! I'm no expert, but from what I've read, crappie aren't ideal in that small of a BOW, so you might have constant balance issues to fight with. Also, the amount of fish a BOW can hold has many variables such as aeration, feeding and fertilizing. Without knowing more details, it'd be hard to give concrete advice. I read a quote on here that said something like, "if you're wondering whether you should remove or release a catch from your pond, err on the side of removing it," and of course I'm paraphrasing here. My uneducated guess would be to keep removing, but the experts should chime in shortly.
