Pond Boss Forums STOCKING A NEW POND Creating the food chain Threadfin shad or Gizzard shad?

Thanks guys. I believe the schools of shad that I am seeing are small fish based on the size of the ripples I see on the waters surface. The size of the circle of ripples and with my experience seeing them in my pond over the past 5 yrs tells me the fish might be pretty small, maybe only an inch or so long. So I was wondering if it was harder to tell what species of shad when they are small? I may just have to seek out the larger 2 to 4" sized in order to identify the fish species.
