Shifting stage-specific constraints on productivity shape recovery potential for Yukon River Chinook salmon. [PDF]
Ecol ApplAbstract Identifying key life history periods in which population productivity is constrained represents a persistent challenge in conservation and natural resource management. For species with complex life cycles, such as Pacific salmon (Oncorhynchus spp.), population dynamics may be shaped by interactions between natural and anthropogenic impacts ...

Age characteristics of walleye pollock school echoes [PDF]
ICES Journal of Marine Science, 2006 Abstract The purpose of this study was to investigate the possibility of identifying the age of walleye pollock (Theragra chalcogramma) using acoustic information. Acoustic data targeting walleye pollock were collected at 38 and 120 kHz from 16 June to 12 July 2000 in the Pacific, off Hokkaido, Japan.
