I'm not a plant whiz but have used grass carp several times on various weeds.

For 3.5 acres, you don't have enough carp. I generally use about 10 per acre. The first year you won't see a lot of results. However, they keep eating in Spring when the plants are getting started. In the second year, if stocked in proper numbers, you should see good results.


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.
