Long‐Term Changes in Dominant Fisheries Species and Their Relationship With Surface Oceanic Conditions in the Waters Around the Korean Peninsula From 1980 to 2019

Fisheries Oceanography, Volume 35, Issue 2, Page 267-284, March 2026.
ABSTRACT The waters surrounding Korea are an economically–ecologically important region due to their high fishery productivity and role as seasonal migratory routes for the spawning and growth of commercially valuable species. We evaluated temporal changes in dominant fisheries species in encompassing large marine ecosystem (LME) areas 47, 48, and 50 ...

Community structure and range shifts in Arctic marine fish under climate change

Ecography, Volume 2026, Issue 1, January 2026.
Arctic marine ecosystems are rapidly transforming due to climate change. Warming temperatures and shrinking sea ice are enabling boreal fish to expand northward, possibly disturbing cold‐adapted Arctic species assemblages. Species range shifts have been documented in the Bering and Barents Seas, raising concerns about ecosystem restructuring.

High-density element concentrations in fish from subtidal to hadal zones of the Pacific Ocean

Heliyon, 2018
Anthropogenic use of high density, toxic elements results in marine pollution which is bio-accumulating throughout marine food webs. While there have been several studies in various locations analyzing such elements in fish, few have investigated ...

Survey of fishes and water properties of south San Francisco Bay, California, 1973-82 [PDF]

, 1989
The objective of this study was to describe the physical and ichthyological changes occurring seasonally and annually in the south San Francisco Bay, based on the results of 2,561 otter trawl and water samples obtained between February 1973 and June ...

Marine fish may be biochemically constrained from inhabiting the deepest ocean depths [PDF]

, 2014
No fish have been found in the deepest 25% of the ocean (8,400-11,000 m). This apparent absence has been attributed to hydrostatic pressure, although direct evidence is wanting because of the lack of deepest-living species to study.

A video dataset for hadal snailfish along with the benchmark

Deep Sea Research Part I: Oceanographic Research Papers
Abstract Application of deep learning technology for deep-sea ecological studies is still in its infancy stage especially in the field of automatic taxonomic identification and statistics. In this study, we created a novel dataset containing annotated videos for the rare species of hadal snailfish inhabiting in >,6000 m depth, and conducted ...

Biogeographic Changes in a High Latitude Marine Fish Community: Short‐Time Reversals in Response to Climate Variation

Diversity and Distributions, Volume 31, Issue 11, November 2025.
ABSTRACT Aim Determine whether changes in fish biogeographic composition and key facets of biodiversity are reversible at short time scales in a high latitude marine ecosystem experiencing ocean warming in the context of a recent short‐term cooling, and an increasing then declining dominant apex predator population. Location Barents Sea. Methods Survey

Trophic Structure and the Isotopic Niche Dynamics of the Tasiujaq (Eclipse Sound, Nunavut, Canada) Marine Food Web

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 9, September 2025.
ABSTRACT Rapid warming in the Arctic is causing cumulative impacts on ecosystems, including widespread reduction in sea ice extent, resulting in shifts in primary production, which can have cascading bottom‐up trophic influences on marine food web structure and function. Understanding trophic interactions and the structure of local food webs across the

Biodiversity as an index of regime shift in the eastern Bering Sea [PDF]

, 2006
Data collected from an annual groundf ish survey of the eastern Bering Sea shelf from 1975 to 2002 were used to estimate biomass and biodiversity indexes for two fish guilds: f latfish and roundfish.

Backward swimming in elongated‐bodied abyssal demersal fishes: Synaphobranchidae, Macrouridae, and Ophidiidae

Journal of Fish Biology, Volume 107, Issue 1, Page 52-62, July 2025.
Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...
