Cecil:
Speaking about growth in cages, what size were the BCBG that you put in the cage this Spring, and what size are they now? How many did/do you have in the cage? It's 4'x4' correct?
BCBG? Most likely Bordello bluegills as I put some of mine in with the Condello broodstock bluegills.
The next one is about 250 4 to 6 inch Bordello bluegills
I think they started out as 3 to 4's. I don't know for sure the size right now as I haven't taken any out and measured them. The last time I removed three to show an aquaculture group they floated up a couple days later most likely due to the warm water. I will tell you they are eating 5D05 with no problems.
If they are typical I should have 6 to 7 inch fish by the end of the growing season. Very robust in appearance too.
