Book Description
Excerpt from Zooplankton Volumes Off the Pacific Coast, 1959 The method used for determining the wet plankton volume of a sample by displacement is as follows: The plankton is separated from its preserving liquid (3-percent formalin) by filtering, allowed to drain, then placed into a graduated cylinder to which is added a known volume of 3-percent formalin. Two volumes are obtained for each sample: (1) the total volume of all plankton material and (2) the volume of smaller organisms after removal of larger organisms, such as jellies, fish, squid, salps, pyrosomes, larger mollusks, and larger crustaceans. Larger organisms are those with individual volumes greater than 5 cubic centimeters (except juvenile or adult fish).

Book Description
Basic data on volumes of zooplankton off the Pacific coast in 1958 are given, together with haul data for all plankton hauls taken on survey cruises of the California Cooperative Fisheries Investigations. Plankton volumes over the entire survey area averaged less than one-third as much as during 1951-56. Distribution charts showing relative areal zooplankton abundance by month are included.
