Anyone have experience raising HBG in an aquaculture setting. I'm curious of their growth rate. Thanks

I have and ran them in parallel to pure Northern Bluegill. Indoors the pure NBG grow faster. Even better if you can get them is RE x NBG. We always have a few running with out best BG and the RE x BG compare very well. No publication to back latter up, but will stand firm behind it.

Jim were the NBG tests single sex (all male NBG)?

There are studies on growing HBG for food which contain some interesting data.
