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

Product update:  All six bay and larger bottom cages now come standard with a third middle foot under the dividers for added support


Floating Grow-out Systems

 Woods Hole Oceanographic Sea Grant Program has published a paper comparing "bottom gear which includes cages, hanging baskets, rack & bags, and stacking trays"  to "Floating gear".  The short version is the oysters always grew faster with less mortality in the floating gear.  If you can get permitted for the surface, do it, you will have more oysters to market sooner.

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.

LowProGrow on dry land with the floats flipped underneath to simulate the cleaning position keeping the cage above the water to kill off the secondary spat and fouling.  Northern growers can easily remove the floatation via the end doors on the float chambers for settling the LowPro's to the bottom for wintering over.

The initial 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, a one man operation, easy to handle, convenient to work with, providing a superior and faster growing product than is possible from a bag.

If you can surface grow on your grant the OysterGro system is a product to consider,  Over the years we've shipped thousands all over the Atlantic coast, they have been a home run for the pro growers who can take it to the top of the water column. If you can float your gear take some time and look it over.

The New OysTube for the Oyster Gardener



Hanging Commercial Basket System

 We've been getting calls from growers looking to replace and upgrade from their ageing and either brittle from UV or worn out plastic Australian hanging baskets.  These pro growers were looking for a more durable and flexible system to grow out their oysters on the horizontal hanging lines.  The products from down under, all well done,  include BST, Seapa (shown above), Hexcell and we are led to believe some others as well.  They are limited by the fact these cages are all  injection molded in plastic and only available in a few predetermined sizes requiring you to tailor your operation to the existing molds rather than the product accommodating the customer's needs.  Ketcham's presents you a vinyl coated marine grade mesh that one will instantly see is more transparent to the flow of the nutrient rich water that grows our oysters than the thicker plastic strands on the imported products. Our Ocean Mesh has been proven as the most cost efficient rugged material over decades in the lobster fishery.  Wooden or plastic lobster traps have disappeared from the working waterfronts giving way to the superior performance of the vinyl coated galvanized mesh.  We use a stainless steel, not plastic, hanging clip system.  You gear is literally hung on commercial swordfish snaps proven for years in the offshore longline fishery,  it is the strongest most fail-safe hanger we could find. Ketcham's being you local in house manufacturing operation we can tailor the sizing of your baskets to your needs, not too big or small, and get them out the door in any quantity you require.  We offer them to you deployment ready or in kits as you prefer in mesh sizes to suit your needs.  Get the superior gear, competitively priced, with the steel soul made just the way you want it right here in the USA.

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.

MeshCaps     Max Your Bags  Max Your Profits

If you box up your square mesh bags, cutting down about 3 inches per side you lose 6 inches per bag, about 15% compounded on every growth cycle.  MeshCaps let you profit from the whole bag, boxing it up with the strength of steel.  The hinged top folds over on the 3 non-hinge sides for a secure seal, the bottom a fitted "shoe box top" that slides into the bag and is permanently secured with stainless steel hog rings.  Any pro-grower that has tried knows a tray will grow a superior oyster compared to a flapping bag, the tray has no nooks or crannies for the critters to get stuck in and better self cleaning movement in the open spaces allowed for the "guests".  Here is a proven way to cheat the tray for just a few bucks and compound  your profit on every cycle using the whole bag.
