Monster Shad and new fishfinder

[iamthesmf]

In the first attachment the three shad from top to bottom.
Threadfin (Yellow Tail and tarpon mouth)
Gizzard
Gizzard (round bull nose)

Also you can cut one open and find the gizzard they use to process the plant and algae with.

Other ways to tell the difference is the threadfin are very fragile and die quickly. Gizzard shad have armor for scales and have a smell that will not wash off very easy.
