Aquaculture Products

Ketcham's is your source for most anything the pro-grower needs to get the job done except we don't sell seed, but if it's not alive we can probably help you out.  Thanks for looking.

Wire mesh trays racks or cages

Deployment ready or supplied as kits


Growers have been coming to Ketcham's since the 70's for design and fabrication of kits, trays, racks, and cages.  We buy the vinyl coated mesh by the trailer load to keep your costs as low as possible.  We always keep an eye open out for discounted, overstock, short rolls, and mis-cut panels to pass along the even better pricing to your business.  Ketcham's has CNC shearing and assembly departments to mill your mesh and get you the best pricing and service in our industry.


Stacking cages are also available as pre-cut flat kits in any mesh size

You can get the bag racks as pre-cut kits too



Over 350 in stock at our New Bedford location in March 2015 and more available. $25 each, you have right of selection, but leave the stacks the way you found them less your keepers.

All sales final, Limited quantity.



Exclusively from Ketcham's,  a newly designed and tested low profile floating grow-out system for oyster gardeners and commercial growers that embrace the superior benefits of a floating reversible self cleaning system but can't or choose not to physically handle the big four or six bags designs now on the market.  Your LowProGrow floats only a few inches above the surface in the growing position and is therefore less intrusive to your neighbors, and your oysters will be feasting at the very top of the water column rich in plankton.  No bags are required in the LowProGrow as we offer the your cages in half, three quarter and one inch mesh, this translates to a substantial cost saving for larger operations.  The bagless systems have historically grown a better oyster, the easier movement in the wire mesh trays promotes breaking off the thin tip of the shell resulting in a deeper cupped product for the lucrative half shell market and all the small oyster collisions in the rocking trays result in cleaner shells needing less processing at harvest


Easy access to your oysters as the door opens wide when in the cleaning position so you don't have to drag your LowProGrow's up to dump them and cull things out.  A smarter way to grow and maintain your crop.

The intitial 2014 season went so well on the grant pictured above,  the grower has indicated he wants six hundred more LowProGrows for the 2015 season.  There's nothing like it, easy to handle, convient to work with, providing a superior and faster growing product than is possible from a bag.

Custom Made Growing racks                          1" X 1" mesh trays 12" deployed height



Ketcham's has designed and manufactured 36" X 48" X 4" stacking oyster trays since the late 1970's but being first doesn't mean we're not always innovating for the growers.  In addition to the old standard 1" X 1"  pictured above there is also half inch square mesh available and the new exclusive three quarter inch mesh designed by Ketcham's as a reasonably priced solution for you to keep the smaller critters from "growing into" the one inch.  The design has been a home run for the folks out on the grants, great water flow and the freedom to move keeps the oysters cleaner and promotes a deeper cupped shell suitable for the premium half shell market.  Stop by and have a look. Single, double, triple, or as high as you want the stack to fit your needs and we can do them as kits for you to save on the shipping.

The Aqua-Float

Keep your bags on the surface with a rugged float for a lot less

These guys are high density and the only UV stabilized (this is huge) float available to the growers for a long service life, it's time to stop beating you brains out with the "noodles".  In stock now exclusively at Ketcham's dimensioned at 2"X 4" X 32" that will give you close to the same buoyancy, about 8 pounds, as the hollow plastic floats for around half the cost each.  The closed cell foam can be cut and shaped for custom needs without losing floatation.  Should you prefer the hard hollow bag floats we have those for you too.
