Agwé

Agwé (also spelt Goue, Agoueh, or Agive), is a loa who rules over the sea, fish, and aquatic plants, as well as the patron loa of fishermen and sailors in Voodoo.
Worship.
His colors are blue, white, and occasionally sea-green or brown. His "veve" (ritual symbol) is a boat with sails. His symbols are painted shells, painted oars, and sea life like the seahorse and starfish.
Offerings.
Small offerings to Agwe are dropped overboard in deep ocean water. Large offerings to Agwe are left on constructed rafts ("barques d'Agwe") which are floated to sea. If the raft sinks, it is accepted; if it returns to shore it is rejected.
His offerings include: 
mirrors, toy ships or scale ship models, oars or paddles, sea shells;
champagne, naval rum, coffee with sugar and cream, white cake, cane syrup, olive oil; 
male ducks and white rams or goats (they are prepared, cooked, and then placed on plates as a sacrifice; as king of the seas, Agwe doesn't get hot food at home).
