There is ultralight and then there is...

Pretty cool obsession - those little fish are photogenic, and he fishes some really interesting places. Would have liked to see more about his tackle, but couldn't navigate his site well enough on the iPad browser and ran out of patience. Still, cool stuff!

Next up... fishing with spider silk.

I have used a #24 midge pupa fly to catch bait and caught bluegills that small. You are allowed to use them as bait as long as you legally take them. One thing I learned with this is to get very close to shore and don't let that tiny midge on a tiny tippet land in more than a few inches of water; larger panfish will readily take it and snap the tippet.
When I was a kid, my dad and older sister had aquariums and on a couple of Florida trips we seined for tropical fish. They got some really interesting fish, though dad learned a lesson about amateur tank stocking. Some of those beautiful tiny fish turn into big uglies rather quickly and they get big by eating everything else in the tank...

Growing up we used to catch river shiners using some black sewing thread, a green twig, a minnow hook, and a piece of hotdog. It was a great way to pass the time waiting on a catfish or drum to take our bait off the bottom.

On a related note, anybody else remember minnow hooks? We had ours in an old methiolate bottle.

Say there blue--you have to be a "certain age" to even remember the bottle. Any older and you have trouble remembering anything.

He is my age. Don't give him too much trouble.

What were we talking about again?
