The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Ecosystem Functioning Under the Influence of Bottom-Trawling Disturbance: An Experimental Approach and Field Observations From a Continental Slope Area in the West Iberian Margin

Frontiers in Marine Science, 2020
Understanding the effects of bottom-trawling induced changes in benthic community structure, diversity and ecosystem functioning across different benthic-size components is imperative to determine the future sustainability of bottom-trawling fisheries in

Comparing environmental metabarcoding and trawling survey of demersal fish communities in the Gulf of St. Lawrence, Canada

Environmental DNA, 2021
Biodiversity assessment is an important part of conservation management that ideally can be accomplished with noninvasive methods without influencing the structure and functioning of ecosystems.

Small mesh trawling [PDF]

, 1970
Experimental trawling operations for bottom fish were first begun in 1920 and consisted of surveys of the continental shelf around Ceylon and the west and east coasts of India.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Assessing the overlap between fishing and chondrichthyans exposes high‐risk areas for bycatch of threatened species

Ecosphere
Chondrichthyans (sharks, rays, skates, and chimaeras) make up one of the oldest and most ecologically diverse vertebrate groups, yet they face severe threats from fishing, necessitating improved management strategies. To effectively manage these species,

Atmospheric CO2 emissions and ocean acidification from bottom-trawling

Frontiers in Marine Science
Trawling the seafloor can disturb carbon that took millennia to accumulate, but the fate of that carbon and its impact on climate and ecosystems remains unknown.

Trawling in the Mediterranean: An Exploration of Empirical Relations Connecting Fishing Gears, Otterboards and Propulsive Characteristics of Fishing Vessels

Frontiers in Marine Science, 2019
Fishing pressure is often expressed in terms of a vessels physical attributes, like tonnage and engine power, while a common definition of fishing capacity identifies vessel size as a convenient proxy for the size of the gear used.

Immediate effect of trawling on sea bottom & its living communities along Kerala coast- Winter School on Towards Ecosystem Based Management of Marine Fisheries – Building Mass Balance Trophic and Simulation Models [PDF]

, 2004
Otter trawling, the most widely used towed bottom fishing gear, is known to have a wide range of impact on benthos. Seabed disturbance by mobile bottom fishing gear has emerged as a major concern related to the conservation of essential fish habitat ...

Toxic Metals in Dried Marine Fish and Implications for Human Health in Bangladesh and Exporting Countries

Food Safety and Health, EarlyView.
This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...
