You bet it has!
In France, the April fool is called "April fish". The reason for that is an old medieval tradition. On that day, people used to try and hang a fish to someone else's back without them noticing, as a practical joke. This habit still lives on today, although fake paper fish have replaced the medieval fresh ones (or were they dried? I somewhat doubt the "street-practicality" of stealthily fastening a fresh fish to someone's back without being given away by the smell).
Why fish? I don't have the slightest clue. But the fish is strongly bound to April fool's day in France, somewhat like the bunny to Easter in Anglo-Saxon countries (no idea about that one either, by the way. In France, Easter symbols include the compulsory eggs, chickens and bells, but no rabbit. Go figure...)
