I fished for bluegills in a pond when I was a kid and loved it. I still do.
You seem to be assuming that pond fishing bluegills is inferior to any sort of trout fishing, including the opening day type of fishing, where people are packed in, fishing for stocked trout.
No way. I would much rather fish a good bluegill pond than fish that way. And I thought so as a kid, too.
Particularly for young kids, fishing on a good bluegill pond or lake is the best way to introduce them to fishing. It's fantastic fun. I'm thankful that my parents introduced me to fishing that way.
If my earliest exposure as young kid had been the crowded type of opening day fishing, I might not have got interested in fishing.
I did a lot of fishing for bluegills from when I was very young, then started bass fishing in those ponds. The first time I went trout fishing, I was about 12 or 13 and it was doing that opening day fishing on a crowded stream. I didn't enjoy it. The people were so packed in that you couldn't get a place to fish the good pools. Some had camped overnight and roped off "their" area. There was trash all over the place. People were hooking each others lines continuously.
Some people have nostalgia for that type of fishing, and think of it as a "tradition" etc. That's putting lipstick on a pig, IMHO. It's a degraded form of fishing.
When you're fishing for bluegills in a pond, you're fishing for wild fish. And they are beautiful, colorful fish.
