How many cultivated forms of native fishes are there? For example, the red rosy minnow which are cultivated form of fathead minnow.
Some are naturally in the wild, some are bred in aquarium.
I only knew few of cultivated forms:

Gold Heterandria formosa
Balloon flagfish
Red rosy minnow
Albino fathead minnow
Innes Gambusia
Albino Gambusia
Gold Gambusia
Albino Channel catfish
Gold trout (rainbow/golden cross)
Albino rainbow trout
Blue rainbow trout
Melanistic Golden topminnow
Melanistic sailfin molly
Melanistic Eastern Gambusia
Golden Bluefin killifish

Also I want to know if the cultivated forms of native fishes are bad or good for us? Im not looking for trouble but like to talking about it. Im not against both naturally/ cultivated forms (maybe balloon flagfish).

Include the following as cultivated (cultigenic) natives (not all distingishable based on phenotype excepting behavior / performance but most can be based on genotype):
Channel catfish (albino does not count wit this one)
Blue Catfish
Largemouth Bass (domestication as food-fish)
White bass
Atlantic Salmon
Bluegill (we are doing now as a food-fish)

Traits selected for by culturist most likely not desirable in wild / locally adapted populations. Cultigens more likley to be moved about owing to either ease of culture or unique attributes. I wonder if hatchery selected stocks more disruptive to native allele complexes than transplanted wild stocks?
