TM and since their initial sea trial in NH, have made many advances to their
containment system. The American Soybean Association International Marketing
(ASAIM) came forth with the Ocean Cage Aquaculture Technology (OCAT) system
(Fig. 3.7c). The 100 m
3 cage OCAT (2 m  4.5 m  7 m) was constructed of
HDPE pipe with galvanized steel fittings. Chain ballast hangs below the lower cage
rim providing a restoring force. The net chamber is formed by attaching net panels to
the cage framework. Engineers at UNH designed and evaluated components in the
cage frame to make it a submersible system (DeCew et al. 2010b). Information
gathered at the UNH OOA site helped these three companies improve their containment systems and increase global sales.
