Average Growth of Clams
New Clam Cage 7-3-2006
The float is a little less than 6' wide x 6' long. The outer frame is 2x6's and the parts are a combination of 1/2" plywood and 1/3 boards. Floatation is provided by blue deck foam.
This is a shot of the float provided by Allen Daggett. it's located in Cape Porpoise.
The trays are made from a 5 gal. plastic bucket cut down to 8". Strips of Garland salvaged from a paper mill were used to form the outer rims. Fiberglass window screen was used to make the bottom.
The barrels are 30 gal. The top was cut open and a hole was cut in the bottom. 1/2" mesh was placed on the bottom then fiberglass window screen was placed on top. The screens were held to the barrel with a lexan ring bolted to the bottom. Three bricks were added as weight and also to keep the bottom tray off the screen. The bricks were wire tied in place.
The barrels are supported by ropes attached to plywood frames. 1x3's run accross the supports act as stiffeners.
The trays drop into the barrels thru the top and the whole thing is covered with a piece of plywood to keep predators out.
In addition to the plywood, some of the 1/2" mesh screen was attached to the top of the barrel.
Our baby's!!! They measured about 5mm long and 2mm thick.
Since the clams were so small we placed them in mesh bags made from some of the window screen. 10 trays with 10,000 clams in each. We used 2 barrels and 7 trays.
Putting the baby's to bed in the nursery.
