Trident of fish commanding

The trident of fish commanding appears to be a barbed military fork of some sort. However, its magical properties enable its wielder to cause fish within a 60-foot radius to fall under empathic command. These fish will not attack the possessor of the trident or any creature within 10 feet of him. The wielder of the device can cause fish to move in whatever direction is desired and can convey messages of emotion (i.e., fear, hunger, anger, indifference, repletion, etc.).
