I wanted to ask all the successful shrimp breeders out there how they manage the genetics of their colonies. I've seen some people do colony mixing with other people, and swap part of their colony with multiple people to increase the genetic diversity.
Is the only importance of this the health of the baby shrimps? Obviously a colony that grows only by interbreeding will eventually become more sensitive and subject to disease. But can you also get much better coloration in the babies by doing this?
I see that the only problem with culling the colony in order to get better color is that you periodically reduce its size and reduce the genetic diversity of the next generation.
