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.

Biogeographic Structure and Mitonuclear Discordance Reveal Cryptic Diversity in Pacific Herring (<i>Clupea pallasii</i>). [PDF]

Ecol Evol
As a critical trophic link, the health and stability of Pacific herring (Clupea pallasii) populations have implications for other marine species, including several targeted by large, productive fisheries. We identified two distinct populations of Pacific herring in the North Pacific, mitonuclear discordance in the Gulf of Alaska, and cryptic diversity ...

Potential Impact of Late 1980s Regime Shift on the Collapse of Walleye Pollock Catch in the Western East/Japan Sea

Frontiers in Marine Science, 2022
Walleye pollock (Gadus chalcogramma) caught in the Korean fishing area dramatically decreased in the late 1980s. To investigate the potential impact of the late 1980s climate regime shift on the collapse of the pollock catch, we developed a three ...
