Went looking for bait today and thought I had hit pay dirt. Lots of schools of what I thought was bait in our cove. Turned out I caught just a couple shad, and the rest were baby stripers 6 or 8 in. Man, i hated netting those stripers. Got them back in as quickly as I could, but I'm sure it wasnt healthy for them. Here's my question: is there anything I should be looking for on the sonar to help tell a school of shad from the schools of baby stripers? I only have a HDI downscan, but I was wondering if it's possible to get a hint from the display which is which. Probably a dumb newbie question, but I thought I'd ask.
