I don't know where it is documented - the combination of moving water and fish
is so common sense that I wonder if anyone *studied* it.

Oh you bet they've studied it and ARE studying it well, with our taxes of
course. ;o) Not sure if it was the website LRob displayed as I don't have
time to look, but I know last year I found lots of good info, in particular
was how a skimmer can work quite well at doing them in.

One concern I have for our area is regarding the Pac. Treefrogs, who like
the same little ponds they put those gambusia in, without thought it seems.
