MD is the state that caused all this snakehead ban in the US and now they are changing the laws saying that you can keep certain ones? i mean, i was a marylander once, but thats just f'd up!
Actually is was an idiotic moron that released an exotic fish that caused the snakehead ban..To clarify what MD did: They had an emergency order that banned all species not a law. When the actual law was written they figured no need for the blanket ban (Lacey act killed them anyhow) so just went with argus and maculata for the books..
As stated above you can't buy, import or transport them anyhow under they Lacey act so in all reality unless you find someone in the state that will give them to you it is pointless anyhow.. even if they are legal to possess by state law.
