The biologist holds a bay scallop (Argopecten irradians) shell on which may be seen attached oyster spat. The wire mesh bags contain dead oyster shells, also used as spat collectors.

Routine collections of biostastical data include length measurements of several species of fin fish and shell fish. Shown here is a sea scallop shell being measured on a recording measuring board.

Raft-culture of oysters, used widely in Japan, is under study by Woods Hole Laboratory. The biologist is holding a string of bay scallop shells used to collect oyster spat. The string of shells will then be hung beneath a raft where the spat will grow to adult, commercial-size oysters.

Large catch of calico scallops on the deck of the OREGON

Shucking out the sea scallops. The lights are for work at night. Shelters were later put over the shucking boxes to give the shuckers some protection from the weather. Probably on ALBATROSS IV.

Chart of the Georges Bank sea scallop grounds. The lightly shaded area provided about 20 percent of the total catch, the stippled area about 25 percent, the crosshatched area about 25 percent, the dar stippled area about 25 percent, and the black area about 10 percent. Oddly this map looks like a fish.
