The temperate water fisheries for albacore in the North Pacific seem to exploit somewhat similar segments of the respective populations present in the various localities. It is clear that in most of the exploited populations two or at most three year classes are highly dominant. In the California fishery from...
This volume of the PMFC bulletin focuses on salmon troll fisheries, with descriptions of the California and Oregon fisheries as well as a research report on the Washington State troll fishery.
This is the second report of a study designed to establish the
current patterns and water mass characteristics existing along the
Oregon coast. Surveys reported on previously were concerned with
monthly samples from a maximum depth of 100 feet and out to 25 miles
offshore from Newport, Oregon. Since December...
This report includes the temperature and salinity data collected at nine shore stations along the Oregon coast from the Columbia River south to Bandon, Oregon. The purpose of this study is to obtain basic information and to supplement our monthly offshore oceanographic survey cruises.
Improved nonirrigated pastures consist of subterranean clover) New Zealand white clover or lotus major (big trefoil). These legumes are generally planted with perennial or H-1 ryegrass, alta fescue, orchardgrass, or meadow foxtail.
Fertilizing weeds and weedy grasses (bent, velvet, and June grass) seldom pays.
This is the third data report of a study designed to determine the
current patterns and water mass characteristics along the Oregon coast.
The first report covered the period July 1958 to July 1959 (Wyatt and
Callaway, 1961). During that year observations were taken to a maximum
depth of 30...
Knowledge of the pelagic organisms in vast areas of the open ocean is very limited. This is particularly true of the small nekton or swimming forms such as fishes, squid, prawns and euphausiids, which are important as intermediate animals in the food chain and are preyed upon by species such...
During 1961, a program of shore station sampling of ocean temperatures
and salinities was carried out by the. Oceanography Department of Oregon
State University. This is a continuation of the work reported by
Kujala and Wyatt (1961). Sampling was conducted at 11 locations along
the Oregon coast and at one...
Our major effort since initiation of this contract has been directed
toward (1) procuring the gamma-ray spectrometric equipment and integrating
the components into an operational system, and (2) analyzing
the samples obtained from the midwater trawl program of the Department
of Oceanography and evaluating and interpreting the resulting data
Analyses...
