Book Description
The report contains tabulations of net zooplankton data from 434 quantitative samples collected during 1961 and 1962 on the Research Vessel Brown Bear off the Washington and Oregon coasts. The samples were collected in key areas in and around the Columbia River effluent to provide a description of seasonal variations of distribution and abundance of plankton associated with changes in the discharge of river water. Identification and enumeration of copepods was stressed. (Author).

Book Description
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.

Book Description
Fisheries science in North America is changing in response to a changing climate, new technologies, an ecosystem approach to management and new thinking about the processes affecting stock and recruitment. Authors of the 34 chapters review the science in their particular fields and use their experience to develop informed opinions about the future. Everyone associated with fish, fisheries and fisheries management will find material that will stimulate their thinking about the future. Readers will be impressed with the potential for new discoveries, but disturbed by how much needs to be done in fisheries science if we are to sustain North American fisheries in our changing climate. Officials that manage or fund fisheries science will appreciate the urgency for the new information needed for the stewardship of fish populations and their ecosystems. Research organizations may want to keep some extra copies for a future look back into the thoughts of a wide range of fisheries professionals. Fisheries science has been full of surprises with some of the surprises having major economic impacts. It is important to minimize these impacts as the demand for seafood increases and the complexities of fisheries management increase.

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.
