Advanced Shellevation

                            Tilt to tumble and balance (option 1)

Open valve to port or starboard lift tank{s} on down current heavy side

Let air flow into selected side until enough water is exhausted for oysters to shift by gravity and or wave action

  • Adjust tilt for wave tumble

  • Open valve to elevated side to sink

  • Or raise opposite side to float in level position

                                       Tilt to tumble (option 2)

  • Position bow ( air supply end) opposite of wave direction (usually pointing shore ward)

  • Open valves

  • Let air flow to elevate bow off bottom with gear slightly below surface

  • Waves will shift oysters forward and gravity will shift them toward wave train

                                    Tilt to tumble (option 3)

  • Move to shallow water near shore

  • Sink on inclined bottom so gear is in wave energy

  • Desiccates and grows with low tide

  • Cleans, polishes and scalps shells depending on exposure time and wave energy


Tilt To Tumble

                                                            Off-bottom Shellevators
Shellevators can also be suspended in the water column using accessory overhead floats. Suspending shellevators from the sea surface avoids exposure to bottom dwelling predators such as oyster drills and starfish and could enhance growth. More importantly, the operational bandwidth of suspended shellevators is unlimited by water depths greater than six feet and can be deployed in any water body. Surface floats can be fixed or attached by flexible lines that can be easily attached or removed while the shelllevator is emerged. Current overhead floats are of tubular shape and are attached forward and aft of shellfish containers at right angles to the longitudinal axis. This configuration provides stability from the surface floats during ascent and decent similar to the stability provided by the sea floor when shellevators rest on the bottom.

The “Shoreliner” is a shallow water model pattern after a rectangular barge (8’ x 16’ x 8”) with four 4’ x 8’ x 8’ air tight chambers (Bow port and starboard; Stern port and starboard) that are operated independently. The Shoreliner is ideal for pier operations in shallow areas like Mobile Bay and Mississippi Sound. The waves in these shallow areas naturally and effortlessly tumble oysters resulting in a cleaned, polished and sculpted “double cup” shape while shielding shorelines from the erosive wave energy.
