Studies were conducted during late winter and spring of 1970 to
establish the extent of spawning of Pacific herring (Clupea harengus
pallasi Valenciennes) in the Yaquina estuary, and to define the degree
of egg mortality on certain substrates. Routine surveillance of the
north shore of the estuary provided information on...
The performances of newly-established gravel incubation systems designed to use unfiltered water for production of unfed salmon fry were evaluated at Netarts Bay, Oregon, and at Little Port Walter, Alaska.
Research was divided into two phases. The first consisted of laboratory studies to develop fry quality testing procedures and to...
This investigation demonstrates the feasibility of a
polyculture system using effluent water from land-based
salmon culture systems to feed juvenile Manila clams, Tapes
japonica (Deshyes), and an evaluation of an artificial diet
for feeding juvenile clams. An economic analysis of the
polyculture system was compared to cultures of a single...
Experiments were carried out in fall and winter, 1990
and spring and summer, 1991 , to determine growth and
mortality of juvenile Pacific oysters {Crassostrea gigas)
in effluent from cultured coho salmon {Oncorhynchus
kisutch) , and effluent from salmon in which the red
macroalga Palmaria mollis was cultured. Ambient sea...
Estuarine residence and growth of juvenile chum salmon
(Oncorhynchus keta) from Netarts Bay, Oregon were estimated
from daily-formed growth increments of sagittal otoliths
which are distinguishable from accretion patterns formed
during freshwater residence. Estuarine residence time was
inversely related to the average size at which juvenile chum
salmon entered Netarts...
The intent of this paper is to bring more attention to the mastery involved with film composition as an art form. The research focuses specifically on the life, style, influences, and works of John Williams as a conductor, film composer, and composer. It addresses his biography, filmography, and working relationships,...
Juvenile fall chinook salmon were acclimated to full strength sea water at 66, 73, and 80 days after hatching. Survival in sea water for 14 days was used as the criterion for successful acclimation. The growth of salmon acclimated to sea water was slower over the period of observation (134...
