Floating Upweller System (FLUPSY)

Hoopers' signature seed grow-out system. Our floating upweller grows large quantities of seed while remaining user friendly and customizable.


Hoopers Island Oyster Co’s floating upwellers are specially designed in-house for low maintenance and high efficiency. The unique design incorporates a basket/silo combination to allow easy access to your seed and extend the oysters further into the water column creating more water pressure and higher water flow. Water flow from individual silos is dumped into a centrally located trough with a well and mounted pump to eliminate cavitation.
