Title: Benthic mariculture and research rig developed for diver operations
Author: Hampson, GR; Rhoads, DC; Clark, DW
Abstract: A benthic structure has been designed and deployed in 18 meters of water in the center of Buzzards Bay for two years for the purpose of growing mussels and other molluscs. This structure can also be used for settlement and growth studies of other marine species where long-term field experiments are required. The structure is designed to be deployed on the bottom, and extends vertically 3.5 meters above the sediment surface. The food source consists of detritus suspended from the bottom by the tidal stream (Benthic Turbidity Zone). The structure is based on a design that utilizes materials that are readily available, structurally stable in sea water, and are low in cost. Deployment and recovery of the structure can be done with vessels greater than 7 meters in length. Installation of grow-out ropes, cages, or experiments on the rig by SCUBA divers is facilitated by hooks and snaps which permit rapid attachment or recovery of deployed materials
