Thanks for all the input everyone.
JHAP, I know that Tilapia and GC are only legal in SoCal and used extensively in golf course ponds in palm desert, but do you happen to know the cut off point? We have a local golf course that uses grass carp so it makes me wonder. I've heard south of the Grapevine but I'm not sure and that sounds a bit vague. I think I may be opening a can of worms as I recently found that the fish stocking permitting is a bit cumbersome here in Cali.
The reason that I pose the question is that we installed an aeration system at an irrigation vineyard in response to an algae bloom and subsequent massive fish kill (1000's of blue gill) in October 2006. Although the aeration did a great job of reducing their FA problem, they now have reoccuring duckweed and pond fern blooms. They are so bad it looks like you could walk across it. I have dove the pond and found it to be devoid of any fish. It seems that they had a complete kill. I just thought that perhaps it was the fish that were keeping the DW and PF in check.
Mikey Boy, where do you live? I grew up in San Clemente.
By the way JHAP...I don't own the company. We are a non-profit organization. We didn't plan it that we, that's just what it's become
