Description |
English: Plan of biological raft used at Monomoy Point for growth experiments and spat collecting. The raft, 20 feet long by 10 feet wide, provided with a central well and four trap-doors, was anchored to the Powder Hole in 20 feet of water. Wire cages and wooden boxes were suspended at various depths from the raft. Many kinds of mollusks were caught and raised in these spat boxes. The raft proved particularly useful in the study of the post-embryonic life history, as the scallops 'set' in large numbers on the boxes, cages and ropes, where specimens could be obtained in all stages of development for laboratory examination. Also, many interesting growth experiments upon the quahaug, scallop and clam were conducted in sand boxes
