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.

Shifting Harbor Seal (Phoca vitulina) Diet May Reflect Ecosystem Changes in Skagerrak

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Harbor seals, as generalist predators, can adjust their diet in response to shifts in prey availability; thus, their diet composition has the potential to act as a biodiversity indicator. This study examined the diet of harbor seals in the Skagerrak by analyzing otoliths from scat samples collected in 2020 and compared species composition to ...

Linking Multiscalar Fisheries Using Metacoupling Models

Frontiers in Marine Science, 2020
Marine fisheries are social-ecological systems important for human health and livelihoods. However, research approaches that consider human–nature interactions within as well as between adjacent and distant fisheries are scarce.

Swimming abilities of temperate pelagic fish larvae prove that they may control their dispersion in coastal areas [PDF]

, 2019
The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further

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

Revealing Chronotypes Across Aquatic Species Using Acoustic Telemetry

Fish and Fisheries, Volume 26, Issue 6, Page 1134-1145, November 2025.
ABSTRACT Acoustic telemetry offers valuable opportunities to investigate individual variability in circadian‐related and other behaviours and how environmental cues shape these patterns in wild fish populations. However, this potential has not yet been fully exploited.

New type of canned cod gonads and liver pastes [PDF]

Vestnik MGTU, 2016
The urgency of rational way of processing the offal of the Gadidae family (liver and gonads) for food purposes has been proved. The possibility of using the frozen gonads (milt and caviar) and the liver of the cod in the human nutrition (especially for ...

Application of spatially robust stereo‐BRUV sampling for quantifying fish assemblages in UK marine protected areas

Ecological Applications, Volume 35, Issue 6, September 2025.
Abstract Marine protected areas (MPAs) often lack adequate data on the status of marine assemblages to support evidence‐based management. Stereo baited remote underwater video (BRUV) systems offer a powerful, low‐cost tool for collecting ecological data, yet they remain underutilized in the North East Atlantic, especially compared to more invasive ...

Fish community structure of the middle course of the Bečva River

Czech Journal of Animal Science, 2004
Fish communities of the Bečva River were studied in summer and autumn 2000 and 2001. Electric fishing gear (Honda EX 1000, DC 230 V, 0.75-0.9 kW) was used for sampling. Four sampling sites (Grymov 19.6 r. km, Rybáře 35.8 r. km, Hustopeče 50.7 and Choryně
