With the CITES classification and the Lacey Act/Endangered Species Act, the price for black market aros has sky-rocketed. Now, there's no reason for aro farmers to want to mass-produce wild color strains and repopulate the wild stocks since this would risk having the asian aro removed from the threatened species list. If that were to happen, asian aros would be just another farmed fish with no huge profit. If I was an aro farmer, looking at my farm from a strictly business standpoint, I would probably kill off huge numbers of fry just to keep the demand up. Why raise large numbers, requiring large food/utility/medicine costs, for a small profit when I can raise small numbers, for less costs, and make huge profits. Aro farmers are not necessarily hobbyists. They have running costs, possibly business loans, families that want better lives, and possibly shareholders all looking at the farm as simply a profit gain/loss entity.
The US gov't has less reason to start breeding these fish. Aro farms would take resourses away from farms raising native game fish. And those resources become less and less each year. Several huge hatcheries have shut down, in the last couple of years, due to dwindling profits, increased running costs, and less federal backing/tax relief. And, because of territoriality issues, raising aros would require more surface acreage than raising most food-destined fin fishes.
