Production and recovery of ammonia-N was studied in the second and third trophic levels of a mariculture system on St. Croix, US Virgin Islands. The diatomChaetoceros curvisetus, grown on nutrients in artificially upwelled deep water from 870 m depth, was the food source forTapes japonica. Consumption of the phytoplankton byT. japonica increased throughout the day and decreased at night, and was related to corresponding changes in algal culture density. Feeding efficiency was highest at night… CONTINUE READING
