MetadataShow full item record
A pilot-stage, two-trophic-level, deep-sea water mariculture system was operated on St. Croix, U.S. Virgin Islands over a nine-month period. Antarctic Intermediate Water from about 870 m depth was pumped continuously into two 50,000-liter onshore pools. The pools were inoculated with laboratory grown cultures of the diatom Chaetoceros curvisetus (STX-167) and operated at a turnover rate of 1.15 day-1. Twenty-nine (29) such cultures were started and lasted an average of 17.0 days each. Mean down-time required for deactivation and restarting of cultures was 54 hours.
