A comparison of bay scallop, Argopecten irradians, survival and growth when fed Tetraselmis chui grown in E or f media

Bay scallops, Argopecten irradians, were fed Tetraselmis chui grown in either E or f media. Phytoplankton concentrations were maintained at 8,000 cells/ml utilizing an automated computer control system. On a daily basis buckets were drained and filled with 15 L of 1 mu cartridge filtered seawater. Twice weekly, scallops were removed from the containers and placed in clean 15 L buckets. Shell height measurements were recorded weekly. Scallop survival averaged 98% for both groups. There was no difference in survival of scallops fed Tetraselmis chui grown in either E or f media.
