The purpose of this watershed assessment is to provide an inventory and characterization of
watershed conditions in the Wilson River watershed and to provide recommendations that
address the issues of water quality, fisheries and fish habitat, and watershed hydrology.
The effects of exposure to suspended silt, kaolin and fuller's
earth on growth and condition of Pacific oysters, 16 months of age,
were studied. The exposure apparatus maintained a continuous flow
of turbid water through chambers containing test oysters. Additional
studies measured the filtration rates of oysters exposed to suspended...
A mathematical model was developed that relates the
ratio, R, of two light flux measurements to the mass concentration,
m, of the atmospheric aerosol particles between
a source of parallel light (e.g., the sun) and the measuring
system. R is defined as the ratio of the light fluxes
passing through...
This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared...
The purpose of this study was to compare the Chapter I supplemental mathematics program CAI with other Chapter I supplemental mathematics programs, Prescription Learning and the traditional "pull-out" program, in terms of achievement and retention of mathematics basic skills. There were 577 Chapter I students from 12 middle schools and...
