This is the only episode of the series named for a Blacklister where the title is never spoken. It's established almost immediately that the titular seafood company is a front for the New Martyrs' Brigade and Hasaan Arkani, and they are the principal subjects of the episode.
Oded Fehr has also played a Mossad operative on Covert Affairs (2010), and the Mossad Deputy Director on NCIS (2003).
The actor playing Red's chief of security Baz, Baz, also happens to be a former C.I.A. officer and veteran U.S. Marine who founded an N.G.O. that rescues kidnapped children in the sex-slave trade.
Michael O'Keefe and Anthony Azizi both appeared in the show Criminal Minds (2005) as unsubs in different episodes.
