5 ton silos. The house on top contained the majority of the electrical equipment as
well as the generator for powering computers, pumps, valves, and augers used in
daily feeding. During feed time, a flex auger would deliver feed pellets (5 mm)
from the bottom of a silo to a mixing chamber in the top house. Feed rates were
based upon fish species, size, biomass and temperature. In the mixing chamber,
seawater was added before the feed was pumped hydraulically to individual cages.
The buoy was moored adjacent to the cage grid by three, 750 ton Jeyco anchors.
