Connor, The GSF will feed on the shad OK and the shad should reproduce. GSF only spawn annually so should never be a biomass problem.

The potential downsides that I see are:

150 threadfins aren't much for 1.5 acres but somehow I guess they will find each other enough to spawn.

The biggest downside that I see for our area is that the shad can''t tolerate a really cold winter. I don't recall what temp they die at. But, as I recall, they freeze out here about every 2 to 3 years.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
