One of the staples for Italian people in New Jersey, along with macaroni on the Thanksgiving table (don't start), is to celebrate the "feast of the seven fishes" on Christmas Eve. The tradition's origins is unclear according to eataly.com. In fact, the article also says, "despite its popularity among Americans, many Italians do not even know about the tradition."

Well, we know about it in New Jersey, and growing up in Union City with an Italian grandmother who gave birth to 15 children who all married and had their own kids, we literally needed our own ocean to cover our Christmas Eve feast.
