  • System and method for clam farming
    Patent number: 6953006
    Abstract: A system and method for clam farming includes a supply ship coupled to a clam planter via a supply tube bundle having a plurality of individual tubes. The supply ship has a separation station configured for introducing individual clams into the individual supply tubes at a periodic interval. The clam planter includes an underwater vehicle and a plurality of row components that are slideably engaged with the underwater vehicle. Each of the row components is coupled to one of the individual tubes. As the underwater vehicle travels in a forward direction, the row components plow furrows and transport the individual clams into the furrows as they exit the individual tubes according to the periodic interval. A clam farm results having rows of clams near node points spaced from one another by node and row separation distances.
