The black crappie was evaluated as a pond fish in four experimental
ponds in the Willamette Valley. Two ponds were stocked with
largemouth bass, bluegill sunfish, and black crappie (1:9:3), and
two ponds with largemouth bass and black crappie (1:3).
Total biomass was greatest in the three-species ponds (80 kg/...
Dihalocarbenes have been generated mainly by thermal decomposition
of sodium trihaloacetate and phenyl (trihalomethyl)mercury,
and give gem-dihalocyclopropyl adducts with various steroid olefins.
A new procedure involving the use of sealed tubes makes possible the
addition of dihalocarbenes to sterically hindered olefins. In this manner,
7-cholestenyl benzoate when treated with PhHgCC1₃...
Cyclopropylcyclobutene was prepared via the intermediate
dicyclopropylcarbinyl carbene which was generated by the thermal
decomposition of the sodium salt of dicyclopropylketone p-toluenesulfonylhydrazone.
The successive thermal isomerization of cyclopropylcyclobutene
to 2-cyclopropyl-1, 3-butadiene and to vinylcyclopentene
was studied. Kinetic data were obtained for the cyclopropylcyclobutene
to 2-cyclopropyl-1, 3-butadiene isomerization in the gas...
Behavior and survival in fresh water were studied for three brood years of coho salmon in Sashin Creek, Alaska, from October 1963, until September 1966. Investigations of spawning adults were conducted to determine numbers of spawners, distribution on the spawning grounds, effects on pink salmon, age composition, redd life, fecundities,...
Steroid carbenes have been investigated as synthetic intermediates.
Basic decomposition of 4-en-3-one tosylhydrazones (and
other A-ring systems) gives varying amounts of 2, 4-dienes, and
solvent derived products with diglyme, heptane, tetrachloroethylene,
carbon tetrachloride, benzene and cyclohexene. A method for
separating complex product mixtures was developed and a study of
the...
A study was conducted at Yaquina Bay, Oregon, to determine
the age-fecundity relationships in the striped seaperch Embiotoca
lateralis. A questionnaire was sent to California, Oregon, and
Washington to ascertain what regulations were in effect, and the value
of the family Embiotocidae with regard to the sport and commercial
harvest....
A study of the distribution, relative abundance and diet of
fishes sympatric with juvenile sockeye salmon, Oncorhynchus nerka
(Walbaum), within the freshwater nursery areas of the Naknek River
system was undertaken from 1961 to 1963. The study was part of an
extensive investigation to determine what factors in the freshwater...
