That's what I do at the moment, and just sell the less colourful shrimp as lower grade.

Growing up in a semi rural area I always assumed culling to be killing, it's good to know they are not being popped off for not looking perfect. I know I will probably be seen as a bit soft for this but I see it as a bit harsh to kill mine off when I can just as easily re-home them.
