Some other PB members, as well as myself, have had some experiences where Golden Shiners have perhaps 'overpopulated.'

I've started to doubt how much various predator fish can truly keep GS numbers in check.

Once the GS population is established, I'm starting to feel like they have a negative effect on the spawns of other desirable fish.

So, in your case, I think you want a lot of YP to survive to get to harvesting size, and I'm thinking the GS will reduce your numbers of newly hatched YP.

These are just my opinions.
