The Columbia River Gillnetter is the pilot of the Lower Columbia River commercial fishing industry, keeping fishermen and the public in touch with today's important issues.
This report consists of tables summarizing data regarding streams receiving hatchery-reared rainbow trout since 1952. It includes data such as sources, sizes of fish, and water temperatures at the planting sites. It also averages data from creel reports from 1965-1972.
The L²-error estimates are established for the continuous time Faedo-Galerkin approximation to solutions of a linear parabolic initial boundary value problem that has elliptic part of order 2m. Properties of analytic semigroups are used to obtain these estimates directly from the L²-estimates for the corresponding steady state elliptic problem under...
A vegetation classification based on concepts and methods developed by Daubenmire was used to identify five habitat types and their related phases on the Medicine Bow National Forest: Abies lasiocarpa/Vaccinium scoparium, including the Pinus contorta/Vaccinium scoparium community; Abies lasiocarpa/Carex geyeri, including the Pinus contorta/Carex geyeri community; Populus tremuloides/Carex geyeri; Pinus...
Razor clam diggers were sampled from March through September on Clatsop beaches for number and age composition of the clams harvested and the distribution and number of diggers. Data from beaches south of Tillamook Head was collected as time permitted. Samples of razor clams from Clatsop beaches were collected for...
This report summarizes project progress in FY 1974. Activities were directed entirely at completing the fourth and final phase of work started in 1971, i.e., to survey groundfish resources on the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...

Producing fruit in alternate years (A-Y) in Thornless Evergreen blackberries is economically feasible and a horticulturally sound management practice. The cultural advantages are: less labor is required; pesticide and irrigation requirements are reduced; pesticide timing and application are improved; maturity of fruit is hastened; and mechanical damage to new canes...
