It's a bit difficult to figure out what specifically the guy was being arrested for and I had to re-read the article 2-3 times.
Looks like the main charges are due to violating the Lacey Act multiple times - shipping the hybrid sheep domestically while labelling them as "pure" sheep, while also conspiring to import embryos/sperm of the Marco Polo Goat (central asian) goat, also illegal without permits/procedures.
If the guy was younger, I'd assume he'd be getting at least football numbers in prison given how long the business was running, etc.
