Why cull shrimp?
An honest questing I'm not looking into the morals etc.
I know a lot of breeders cull poorly coloured stock, is this due to bad genes or just a less than ideal colour?
I was thinking about it this morning, in my family almost everyone has black hair, however my uncle and myself have red hair, but still produce dark haired children. I know from breeding guppies that recessive genes will often spring up, only to last one or two generations. Do you get the same with shrimp, or will "culls" only produce more of the same?
