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.

Downunder- 36in. by 14in. by 11in. Holds up to 150 market-size oysters. Hangs on line beneath dock. This cage is being superseded by the tidal  to the right.

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.

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.

Tidal tumbler- 36 in. long by 12 in. diameter. Holds up to 150 market-size oysters. Hangs on line beneath dock. Can be set to tumble automatically with tide change. See diagram below.

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

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