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...
Mankind is facing the spectre of a planet stripped of the resources necessary to sustain the human populations that currently exist-not to mention those unborn multitudes which seem certain to he added in the coming decades. Time is rapidly running out for scientists and engineers to find new resources to...
Due to the development, Japan lost more than half of seaweed beds
because of reclamations, water brake constructions and water pollution
after the WWII. As a result, coastal fisheries production decreased from 2
million metric tons to 1.5 million metric tons. Building a forest in the sea
has been paid...
Clinocardium nuttallii from Yaquina Bay, Oregon, were found to
harbor an algal symbiont in the siphon, mantle and occasionally
the foot tissues. Approximately 35 percent of the population in the
study area was infected to some degree with the alga; however, no
cockles under two years of age were infected....
Following surveys of seaweeds in Oregon and the Caribbean, four algal species were selected for study on the basis of their crude extract biological activity or thin-layer chromatographic characteristics. Extracts were fractionated by normal phase chromatography, including high performance liquid chromatography (HPLC). Derivatives (methyl esters, acetates, and benzoates) of natural...
The term "interaction" in evolutionary biology and ecology
describes the relationships among variables in two classes of causal
models. In the first, "interaction" refers to the influence of a
single putatively causal variable on a variable of interest. In the
second class of models, the term applies when a third...
Aphanizomenon flos-aquae from Upper Klamath Lake, Oregon
was introduced into culture in a precipitate -free medium developed
by modification of McLachlan's ASM medium. This medium ASMT
No. 8 contained no organic substances other than ethylendiaminetetraacetate
(EDTA) and Trishydroxymethylamino methane (Tris),
and was developed by modifying the concentrations of certain elements,...
The major nutrient requirements of the blue-green alga Anabaena
spiroides Klebahn were investigated. It was hoped that the results would allow the development of a balanced culture medium in
which the alga would exhibit rapid growth and retain typical morphological characteristics.
The alga was isolated from Upper Klamath Lake, Oregon,...
