Bruce:
The last time I tried cage culture I had some bullies that really grew quick, and some that looked like they were stunted. How often and how should culling BG in a cage be done?
. Start with fish as similar in size as possible. Once a fish has demonstrated he's a slow grower (you'll know in one month) you have two choices...eliminate him from the program, or have a downgrade cage available and give the slower growers another chance. Three cages would be ideal. Don't handle and sort TOO much however because the handling stress can cost you some of your best fish.
