Wow Shorty, are you near your carrying capacity? I can't imagine having that many in one pass! How do you propose to control all those young RES and GSH?

I started with 50 RES in my small puddle and have not seen a successful spawn now that we are 2 summers past stocking. I stocked them about the size of that tiny one in the plastic bag or container that you have in the bottom picture in the series of pictures above.

IF they create that many young that I get that many in one pass I'll be really worried about catching enough or getting enough predators in to control the population!

I know RES hammer FHM, but do they eat YOY perch or in your case the smaller GSH? Ever check the stomach content of your RES?
