North Pacific albacore (Thunnus alalunga) is a highly migratory and
commercially valuable species of tuna. All stock assessments and management
decisions for North Pacific albacore are presently based on the assumption of a single,
uniform stock. However, a growing body of evidence from diverse sources suggests
that there are two...
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...
Oregon's commercial fishery for albacore tuna (Thunnus alalunga)
is large, valuable, and variable. Little is known, however, about the
oceanographic factors which determine abundance and distribution of
albacore.
Primarily using logbook data contributed by fishermen, this study
compares albacore catches with selected ocean conditions. The study
is limited to troll-caught...
This study investigated long-term (1961-2008) changes in albacore (Thunnus alalunga) abundance and distribution in relation to local environmental and large-scale climate indices in the Northeastern Pacific using time series and spatial analyses. Prior to the time series analysis, a wavelet analysis was conducted to examine nonrandom patterns of cyclical variability...
The disposal of radioactive waste products is a serious problem facing scientists and the public. One solution proposed is to dump these waste products at sea, with the area of northern Oregon and southern Washington in 100 to 1,000 fathoms as one area of consideration. However, one of the problems...
