Abstract

A GPS shellfish trap setting system that indicates when to set shellfish traps at precise locations with controllable distance between shellfish traps to allow for efficient shellfish fishing is provided herein. The shellfish trap setting system receives a GPS signal, processes that signal to determine the precise distance at which to launch a shellfish trap from a fishing vessel, then displays that distance to a control unit monitored by a user. The GPS shellfish trap setting system also includes counters for counting the number of traps set and the number of shellfish deposited into a holding tank.

Claims

1. An apparatus for placing shellfish traps comprising:

a GPS antenna that receives GPS information, the GPS antenna being connected to a microprocessor;
