Zooplankton Volumes Off The Pacific Coast 1957

Basic data on volumes of zooplankton off the Pacific coast in 1957 are given, together with haul data for all plankton hauls taken on survey cruises of the California Cooperative Oceanic Fisheries Investigations. Plankton volumes were larger during February through April than the six-year average for these months, and progressively smaller during May through July than the six-year average. Distribution charts showing relative areal zooplankton abundance by month are included.

Excerpt from Zooplankton Volumes Off the Pacific Coast, 1957: Special Scientific Report-Fisheries No. 326 Plankton samples are used by the U. S Bureau of Commercial Fisheries in studying the early life histories of commercially impor tant or potentially important fishes, including their distribution, abundance. And rate of survival. These collections are also used by Scripps Institution of Oceanography in studies of productivity. These investigations are part of the California Cooperative Oceanic Fisheries Investigations, a program sponsored by the Marine Research Committee and carried out by the Scripps Institution of Oceanography of the University of California. The Bureau of Marine Fisheries of the California Department of Fish and Game. The California Academy of Sciences. The Hopkins Marine Station of Stanford University. And the U. S. Bureau of Commercial Fisheries. Biological Laboratory. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
