problem is - if you can see them, they can see you ... might make them a bit spooky (especially the bigger ones) and cause the little ones (the hungry ones, anyway) to "nip" at the bait. You can try several different things:
downsize ... go to a 1/24oz, 1/32oz, or 1/64oz size jig
put away the "plastics" and go to feather/hair type jigs
use a small plain jighead and put a minnow on it (usually hooked from under the throat and out between the nostrils)
drop your jig (whichever one you choose to use) down past/below them ... then sloooowly reel it back up
stay well back from the edge of the dock ... walk as quiet as a cat ... hold your rod so that the top 6 inches of it are all that sticks out past the edge of the dock ... let out just enough line to put the jig a few feet deep in the water (or just a few inches below the submerged edge, if it's a floating dock) ... and walk slowly along, dragging the jig in the water as you go ... if you have a spinning outfit - you can "jiggle" the line with your "trigger finger" as you hold your rod steady and at the same position as you walk
you can put on a float/marabou jig and cast well down the edge of the dock and slowly reel it back in (again, staying out of sight as much as possible)
you can fish deeper and slower ... there may be bigger fish below the youngsters
you can try the "creek" size crankbaits ... Roadrunners ... Beetlespins ... miniature spinner baits ... in-line spinners (like Rooster Tails or Mepps)
where there's a will, there's a way ... keep trying new things .... luck2ya ..cp
