anthropic, thanks for the clarification.

"Rod, the liver function question relates to the effects of various types of feed on the liver. Some feeds grow the fish nicely, but also lead to a fatty liver that shortens life expectancy. Optimal says their fish food doesn't do this, so the BG will live an extra year or two & get even bigger."

So you're saying that pate de foie gras of bluegill is not recommended!

I knew I was missing a simple caveat on fish feeding, but I am not yet up to that planning stage for my ponds.

P.S. I really appreciate the dedication of so many posters on Pond Boss to insert additional comments and clarifications in the threads that allow people at all levels of "pond knowledge" to follow the conversation.

Thanks,
Rod
