1st pic: yellow (stripe) bass or crappie? Shad might be a smaller/tighter bait ball.
2nd pic: crappie

That's my guess. I have often seen large schools of yellow stripe in Northern Alabama.

Most importantly, you captured some great shots. They can be whatever you want them to be until you get to drop a line.

I recently changed from amber to blue on my 998c and it seems to help. Personal preference drives you to the color that you are most comfortable with.

Lastly, I sure enjoy Rnvinc's knowledge and willingness to share for our benefit. I did not notice the difference in the picture quality when "marking" until he pointed it out.
