Devices and Designs

At the Annual Float-Building workshop and on other occaisons, TOGA will either help you build some of these devices, or will build one for you.  Keep posted with our Newsletters and calendar.

Flipfloat- 39in. by 23in. by 6in. Holds up to 300 market-size oysters. Use with standard ADPI bags.

Bottom cage- 39in. by 23in. by 6in. Holds up to 300 market-size oysters. Use only with firm bottom.  

These ADPI bags can be purchased from vendors offering aquaculture supplies.  The fine-mesh bag on the left is for new oyster spat.  The larger mesh bag on the right is for juvenile oysters 3/4" to 1&1/2 in. long.  Larger oysters do not require a bag if kept in a float.

Some tools we use for making cages.  We also use power or hand saws for cutting the 4 inch thin-wall drain pipe for the floatation devices.  Note- do not use thick-wall (schedule 40) PVC.

Bender- Handy for making your own floats and cages.  Options- 42in.  or 50in.

Taylor float- 3ft. by 2 ft. by 1 ft. Holds up to 400 market-size oysters. With or without lid. Use with standard ADPI bags.
