The impact of bottom trawling on carbon storage in the Oslofjord: Assessing a hidden socioeconomic cost [PDF]

Marine areas and habitats are sources of many ecosystem benefits, but are frequently pressured and disturbed by many human activities. Such disturbances include coastal infrastructure, waste dumping, agricultural runoffs, and fishing.

Assessing the Vulnerability and the Stock Status of the Bluntnose Sixgill Shark, Hexanchus griseus, in North‐Eastern Tunisia (Central Mediterranean) Using Data‐Limited Models

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT The bluntnose sixgill shark (Hexanchus griseus) is classified as ‘Near Threatened’ at a global level but currently holds a ‘Least Concern’ status in the Mediterranean Sea, despite increasing fishing pressure and insufficient data. This study presents the first comprehensive stock assessment of H. griseus in north‐eastern Tunisia (GFCM GSA 13),

The relative effects of bottom trawling, organic enrichment, and natural environmental factors on coastal seabed communities [PDF]

Coastal regions are under intense and growing pressure from human activities. Here, we examine how human and natural drivers interact with benthic communities, species, and life-history traits across four distinct coastal areas.

Influence of seasonality of bottom trawl surveys on assessment of stocks for bottom fish

Izvestiya TINRO
Reliability of the fish stock assessments is affected by many factors, including seasonal patterns of fish distribution and inhomogeneity of distribution density. Results of two bottom trawl surveys are compared, which were conducted in the same area of Peter the Great Bay (Japan Sea) and in the same year 2013 but in different seasons, as spring and ...

Trends in Aquatic Environmental DNA Research in Alaska

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Environmental DNA (eDNA) analysis is an emerging tool with significant potential to advance biomonitoring, particularly in remote and logistically challenging environments. To evaluate the state of eDNA research in Alaska, we conducted a literature review and a regional survey and results provide the first comprehensive overview of eDNA research in ...

Detection and Quantification of Two Flatfish Species in the Sylt Outer Reef: Development of a qPCR Assay and Forecast Model Based on eDNA Copies

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
ABSTRACT Assessing fish diversity and abundance is crucial for effective marine conservation and management strategies, particularly in ecologically sensitive areas such as the North Sea. Bottom trawling, one of the most commonly used fishing methods, is facing growing criticism, even for scientific purposes, and has already been banned in ecologically

Hydrological control of ecosystem functioning in a coastal lagoon

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Located at the land–ocean interface, coastal lagoons are specifically vulnerable to increasing threats from anthropogenic activities and climate change. Understanding the hydrological and ecological responses of these lagoon systems to global and local changes is essential.

Opportunistic feeding by Antarctic krill in the eastern Weddell Gyre

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Antarctic krill, Euphausia superba, is an important species in the Southern Ocean and is vulnerable to climate change. We studied the carbon sources for krill—specifically pelagic and ice‐associated (sympagic) particulate organic matter (POM), representing phytoplankton and sea‐ice algae, respectively—during March 2019 across three distinct ...
