Oysters in the upweller grow at different rates, we use the Seed Shaker Sorter to cull the oyster seed.

We just sorted 500,000 6,8,12 mm seed in 1 hour and 45 mins. This process ensures that the faster growing oysters are removed from the oysters that grow more slowly. A shaker sorter is a fast and efficient way to sort the oysters into liked sized seed which allows us to rapidly class ahead fast growing oysters.

250k-50k per 20 Inch Silo     1mm-3mm Seed

Average Growth Rate .5-1mm a week


Our latest upgraded nursery tanks have been specially designed in house for low maintenance and high efficiency. This new design are built with a deeper slope bottom and a 4” drain to allow for quick and easy cleaning. The new design adds stands to the bottom of the tank and also includes 12 silos with your choice of micron screen. 125, 200, 350, 500 or custom size

 Our tanks allow for upwelling and downwelling, whichever is needed, and are equipped ready to use, except for exterior drain pipe.

Each unit includes:

(1) 10’6” x 5’2" tank

(12) diameter silos equipped with Interchangeable nylon screen and protective bottom guard

(1) 10’6” x 10” trough

Used as a downweller, our tanks are ideal for setting larvae on micro-cultch (crushed shell). They can be setup as a static or flow through system. They can be used as an upwelling system by pumping sea water directly into the tank and draining up through the silos.
For low volume operations (200,000-300,000 animals) this unit could be used to grow seed up to ½”. For larger operations we recommend using this unit to get seed 3/8” and then transferring to our FLUPSY.

100k - 10k per silo 4mm - 8mm Seed

Average Growth Rate .5-1mm a week 

Our floating upwellers have been specially designed in-house for low maintenance, high efficiency and are user friendly. Their unique design incorporates a basket/silo combination. This combination allows for easy access to your seed and extends the animals further down into the water column creating more water pressure, which provides higher water flow. The water flow from the individual silos is dumped into a centrally located trough, which is designed with a well where the pump mounts to eliminate cavitation.


Upwelling unit includes:

¾ hp Ice Eater Pump, 8 silo/basket combos, 1 trough, two 4’x 8’ x 1’ floating dock floats and one 8’x20’ deck
