Hmm...I'd say a lot of people breed a lot of things w/out forethough--dogs, cats, horses (I've owned horses my whole life), and themselves for that matter! I guess I would rather see them breed fish if they have to breed something for a number of reasons: fish are easier to keep than other animals, they can at least usually manage to give the fry away (in regard to space, general care required), people can often not be disuaded from breeding something. I certainly agree with your 'good reasons' to breed fish. Yes most people do regard fish as lower forms of life (not me!). Witness tattoed and dyed fish, if people did that to another animal they would be in big trouble!
Anyway just my two cents

Could amount to the same thing--look at dog breeds, the pure-bred dogs are more likely to have health issues is because they were in-bred to select desirable traits.
