Seabird Prey in Space and Time: Combining Multiple Datasets to Model the Distribution of Sandeel (Ammodytes marinus) and Sprat (Sprattus sprattus) in the North Sea

Ecology and Evolution, Volume 16, Issue 11, November 2026.
Forage fish are key prey and commercial species in the North Sea ecosystem, but estimates of their biomass over detailed spatial and temporal scales is currently limited. To fill this vital research gap we employ Hierarchical Bayesian spatiotemporal models of sandeel (Ammodytes marinus) and sprat (Sprattus sprattus) in the North Sea, providing fine ...

The demersal resources of South China Sea [PDF]

, 1977
Based on the catch statistic derived from the official returns which were offered from all Taiwan paired trawlers operated in the South China Sea, dating from 1969 to 1971, the author made an investigation on the species composition, the seasonal changes

Field Identification of Major Demersal Teleost Fish Species along the Indian Coast [PDF]

, 2019
Based on their vertical distribution, fishes are broadly classified as pelagic or demersal. Species those are distributed from the seafloor to a 5 m depth above, are called demersal and those distributed from a depth of 5 m above the seafloor to the ...

Niche partitioning and host specialisation in fish‐parasitising isopods: Trait‐dependent patterns from three ecosystems on the east coast of India

Ecology and Evolution
Due to their large size and obligate nature, Cymothoid isopods inflict a high degree of tissue damage to fish. Still, they are understudied at an ecosystem level despite their global presence and ecological role.

Drivers of population dynamics vary across biophysical gradients and after ecosystem regime shifts for a freshwater fish

Ecosphere, Volume 17, Issue 11, November 2026.
Abstract Long‐term, cross‐system comparisons can help disentangle global‐ to local‐scale biophysical drivers of fish population dynamics and clarify context‐dependent, nonstationary responses to broad‐scale ecosystem change. Lake Whitefish (Coregonus clupeaformis) is a coldwater, demersal fish species that is socioecologically valuable across its range,

Stock assessment of Demersal Resources in the Gulf of Oman

, 2003
Demersal resources in the Gulf of Oman are one of the main objectives for both industrial and traditional fisheries. In order to implement a rational management of these resources; the research project of “stock assessment of demersal resources in the ...

Variability of Dissolved Oxygen in the Strait of Georgia: Seasonal, Intraseasonal, and Interannual Changes Based on the SalishSeaCast Model

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Dissolved oxygen (DO) variability in the Salish Sea is driven by circulation, deep‐water renewal (DWR), and biological activity across multiple timescales. Using an updated version of the SalishSeaCast model, we investigate these drivers of DO in its largest basin, the Strait of Georgia, from 2012 to 2020. The model's refined parameterizations

Diet composition of fish species from the southern continental shelf of Colombia [PDF]

The diet composition of 30 fish species belonging to 16 families from the Pacific Coast of Colombia is described. Benthic crustaceans (37.5%) and bony fishes (23.7%, chiefly demersal) were the most important food items for the fish species analyzed. Data

Basin‐Scale Marine Heatwave Types in the Gulf of Mexico: Wind–Humidity Controls on Latent Heat‐Loss Suppression and Ocean‐State Modulation of Vertical Thermal Structure

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Marine heatwaves (MHWs) in the Gulf of Mexico (GoM) have become more frequent and intense, yet the mechanisms governing basin‐scale events remain incompletely understood. EOF–k‐means clustering of event‐mean sea surface temperature anomalies (SSTA) during 1982–2024 identifies four recurrent, seasonally dependent spatial regimes: two stronger ...
