Example of Data Sheet of the CSK Zooplankton
Collection (NSM 164, Yamazi, 1971)
Sampling data and result of primary sorting are
shown for each sample.
(The Collection was maintained till March 1978 at
the Regional Marine Biological Centre for
Southeast Asia. The collection was transferred to
Marine Biological Center, Tokai University in
April 1978.)

Management of the CSK Collection

• Data management
• 1) sampling data
• (date, time, position, name of vessels, depth
  of tow, etc.)
• 2) results of primary sorting
• name of taxa, number of animals
• 3) reports from specialists
• name of species identified and record of
  occurrence
• Data of 1) and 2) are compiled using Microsoft
  Excel. Data of 3) are preparing and will be
  finished by March 2007.
• Sample management
• Preservative check
• pH and volume of the preservative in the
  vials
• (5 formalin solution buffered with borax.)
