Hi Funky,
I'll try to give some general info but you'll have to tell us more specifically what your concerns or questions are.

First they are easy to source (bait shop, bait wholesaler, mail order the fish to you)
2. Easy to transfer and transport if you have your own source as they are pretty hardy
3. They scatter sticky eggs rather than make a nest and vegetation helps to get successive generations to survive
4. They adapt to pellet feeding quickly and grow rapidly with regular pellet feeding
5. Lots of debate on this forum on whether they have harmful aspects. Some find them to beat the panfish to the worms on the angler's hooks when fishing but in my MI pond I have not seen that at all. I find that the YP are very quick to the bait but rarely we do catch a larger shiner.
6. There are a few members who have shiner (several kinds) and YP only ponds and somehow the pond doesn't get that much out of balance. It may be that GSH are somehow controlling the young YP population? There is some discussion on whether GSH eat eggs of other fish but I'm not sure we can prove or disprove that yet.
7. They are a great bait fish for LMB and SMB but in my experience they swim very very fast and if the Bass have the option for YP, FHM, or bluegill I wonder how much time the bass would spend chasing them.

8. I also worry about whether the shiners do any rooting in the bottom of the pond and create turbid water? Someone who has a GSH only pond or a GSH, YP only pond might be able to speak to that.

What else did you have in mind?
