Channa marulias has been identified as a species complex and not an individual species and recently published paper in Raffles Bulletin of Zoology identifies bullseye snakehead species in Florida as Channa aurolineata and not Channa marulius and that DNA analysis shows match to populations of C. aurolineata from the Mae Khlong Basin in Thailand.

 

"This study revealed 100% DNA barcode identity between natural Thai populations and the feral Florida population, giving a strong indication that the Florida population was established from a founding population of Thai origin."

 

“Now that the Marulius group as a whole is better understood, we can say with some certainly that the snakehead population in Florida waters is actually C. aurolineata, a species first described by Day (1870), but only recently revalidated as part of geographically wide-ranging investigations of the Marulius group across its natural range (Adamson & Britz, 2018).”

 

 

The Mae Khlong Basin as the potential origin of Florida’s feral bullseye snakehead fish (Pisces: Channidae)

Interesting,  Has anybody attempted to match FL feral jewel cichlids with wild African populations?  My guess is they're a mix from several different locations, but it would be nice to see what story their DNA tells.

Not sure, but that would be interesting to see!
