Engraulis ringens (anchovy) is a small pelagic fish of the Family Engraulidae that inhabits the neretic‐coastal zone from northern Peru to south‐central Chile. It is the main resource species of industrial fishing of northern Chile, representing 80% of the annual landings of the purse seine fleet. The history of this fishery (1985–2023) shows a strong decrease in annual industrial landings, especially

(IF 2.6) Pub Date : 2022-11-30 Yosuke Igeta, Chiyuki Sassa, Motomitsu Takahashi, Mizuki Kuga, Satoshi Kitajima, Taku Wagawa, Shoko Abe, Chikako Watanabe, Takashi Setou, Hirohiko Nakamura, Naoki Hirose
Recruitment of Japanese jack mackerel (Trachurus japonicus) has been decreasing continuously since 2000 in the Pacific coastal waters of Japan. The reasons and mechanisms for this phenomenon are still unclear. Particle-tracking experiments were performed using a data assimilation model to elucidate the effect of a current system on the transportation processes of T. japonicus from the main spawning

Changes in the vertical distribution of age-0 walleye pollock (Gadus chalcogrammus) during warm and cold years in the southeastern Bering Sea Fish. Oceanogr. (IF 2.6) Pub Date : 2022-11-27 Adam Spear, Alexander G. Andrews, Janet Duffy-Anderson, Tayler Jarvis, David Kimmel, Denise McKelvey
In the last 20 years, the southeastern Bering Sea has shifted its thermal variability to longer-term (4–6 years) ocean–ecosystem temperature stanzas. Age-0 walleye pollock (Gadus chalcogrammus) populations respond to thermal changes with horizontal (east–west) shifts in spatial distribution over the continental shelf, though there are limited data on whether thermally mediated vertical shifts in distribution

Effects of oceanography on North Pacific armorhead recruitment in the Emperor Seamounts Fish. Oceanogr. (IF 2.6) Pub Date : 2022-11-15 Madeline A. K. Lavery, Christopher N. Rooper, Kota Sawada, Kari Fenske, Vladimir Kulik, Kyum Joon Park
The North Pacific armorhead (NPA), Pentaceros wheeleri, is thought to exhibit an extended post-spawning epipelagic phase in which larvae disperse to the northeast Pacific Ocean. Current understanding of juvenile distribution, development, and mechanisms that drive recruitment variation, however, remains largely incomplete. The objective of this study was to compare a time series of NPA recruitment

In Memoriam: Timothy R. Parsons (1932–2022) Fish. Oceanogr. (IF 2.6) Pub Date : 2022-11-14 R. Ian Perry
One of the world's pre-eminent marine scientists and the founding editor of Fisheries Oceanography, Professor Timothy (Tim) R. Parsons, passed away peacefully in hospital in April 2022. He was passionate about building a holistic understanding of how pelagic organisms are interconnected in the food-webs of the sea, and about presenting alternative methods for the management of fisheries. For these
