Demersal fish in Icelandic waters

, 2021
A sudden increase in population size and distribution around Iceland took place in several species in 2000-2010. What they have in common is that Iceland is placed at the northern border of their geographic range making the susceptible to environmental fluctuations.

The effect of fishing on demersal fish community dynamics: an hypothesis [PDF]

ICES Journal of Marine Science, 2001
Fishing acts like a predator; it alters the extent of competition and allows the coexistence of competitive species. To test this hypothesis, several component elements are addressed. The variability of biomass in demersal fish communities is analysed to seek evidence that biotic interactions play a role in community dynamics.

Demersal Fish Assemblages in NE Atlantic Seagrass and Kelp

Diversity, 2020
Global fisheries are in decline, calling for urgent evidence-based action. One such action is the identification and protection of fishery-associated habitats such as seagrass meadows and kelp forests, both of which have suffered long-term loss and ...

Beyond connecting the dots: A multi-scale, multi-resolution approach to marine habitat mapping

Ecological Indicators, 2021
Conflicts of interests between economic and nature conservation stakeholders are increasingly common in coastal seas, inducing a growing need for evidence-based marine spatial planning.

Distribusi Target Strength Ikan Demersal Melalui Pengukuran Akustik Secara In-Situ Di Perairan Kahyapu Pulau Enggano Kabupaten Bengkulu Utara

Jurnal Kelautan Tropis
Kahyapu Waters is one of the potential waters for demersal fishing in Enggano Island. Demersal fish resources in Kahyapu Waters if exploited optimally can provide sustainable benefits for local fishermen.

Using hydrodynamics to modify fishing performance of a demersal fishing gear

Fisheries Research, 2023
This study demonstrates how hydrodynamics can be used to influence the fishing performance of towed demersal fishing gears. Sea trials are performed in the sea star fishery to show how modifications to the gear design alter the hydrodynamics of the turbulent wake and consequently affect the catching performance of trawl gears.

Isotopic profile and mercury concentration in fish of the lower portion of the rio Paraíba do Sul watershed, southeastern Brazil

Neotropical Ichthyology
The aim of this study was to evaluate the isotopic profile and mercury (Hg) concentrations in fish (carnivores, omnivores and detritivores) in the lower portion of the rio Paraíba do Sul watershed, southeastern Brazil.

Predicting the effect of seine rope layout pattern and haul-in procedure on the effectiveness of demersal seine fishing: A Computer simulation-based approach.

PLoS ONE, 2017
Demersal Seining is an active fishing method applying two long seine ropes and a seine net. Demersal seining relies on fish responding to the seine rope as it moves during the fishing process.

Seasonal and interannual variability of fish species composition in catches of bottom nets in the Russian waters of the Kunashir Strait

Известия ТИНРО, 2023
Seasonal and interannual variability of the demersal fish species composition is considered for the depths of 70–315 m in the eastern Kunashir Strait on the data obtained in 1998–2014.

Latitudinal effect on the structure of snake–prey interaction networks is mediated by snake species richness

Ecography, EarlyView.
Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...
