As far as a little research goes the Black Salty is none of these:

Related yes...carassius auratus no.Its an engineered fish.
RI has had over 200 years to put a rule in the books?How do you come up with that?They've been tested in TX for 80yrs?Huh?Anderson Farms has only been in business 50yrs.The Black Salty itself beginnings were in the 90s.
As far as predators in other watersheds like in TX.Lets see there's Stripers,Hybrid Stripers,Redfish,Corvina,Gar,several Catfish species.
None of these can be found in NE waters.
The Black Salty has potential but I see a little more scientific research needing to be done before I want it here.
Btw quote all the rules and regs you want it ain't a minnow its a member of the goldfish family.
