Response of demersal fish communities to the presence of fish farms [PDF]

Marine Ecology Progress Series, 2005
The hypothesis that the presence of fish farms affects the communities of wild fish at large spatial scales was investigated through experimental trawl surveys. Three regions of the Aegean Sea with aquaculture zones were sampled in May and September (reproductive and recruit- ment periods, respectively for most species in the Aegean Sea).

Cleaner Fish Labroides dimidiatus Presence Does Not Indirectly Affect Demersal Zooplankton

Frontiers in Marine Science, 2022
Coral reef mutualisms involve complex trophic ecological relationships that produce indirect effects. Excluding mutualistic cleaner fish Labroides dimidiatus from reefs indirectly increases the abundance of many fishes and reduces demersal stages of ...

Marine heatwaves are not a dominant driver of change in demersal fishes [PDF]

Nature, 2023
Marine heatwaves have been linked to negative ecological effects in recent decades1,2. If marine heatwaves regularly induce community reorganization and biomass collapses in fishes, the consequences could be catastrophic for ecosystems, fisheries and human communities3,4.

Taxonomic distinctness of demersal fishes of the California current: moving beyond simple measures of diversity for marine ecosystem-based management. [PDF]

PLoS ONE, 2010
BACKGROUND: Large-scale patterns or trends in species diversity have long interested ecologists. The classic pattern is for diversity (e.g., species richness) to decrease with increasing latitude.

The influence of offshore windpower on demersal fish [PDF]

ICES Journal of Marine Science, 2006
Abstract A significant expansion of offshore windpower is expected in northwestern Europe in the near future. Little is known about the impacts it may have on the marine environment. Here, we investigate the potential for wind turbines to function as artificial reefs and fish aggregation devices (FADs), i.e.

A sensitivity-based procedure to select representative fish species for the Marine Strategy Framework Directive indicator development, applied to the Greater North Sea

Ecological Indicators, 2021
Harmonizing biodiversity assessments under the Marine Strategy Framework Directive (MSFD) at the pan-European level is a crucial task for the Regional Sea Conventions and EU Member States in the coming years, particularly for fish assessment in ...

New records of ray-finned fishes (Actinopterygii) from Puerto Morelos Reef National Park (Mexican Caribbean) [PDF]

Acta Ichthyologica et Piscatoria, 2023
We documented the nearshore ray-finned fishes in Puerto Morelos Reef National Park (PMRNP) by sampling 57 localities, including rocky intertidal pools, sandy bottoms, Thalassia beds, coral reefs, artificial reefs, karstic-slab bottoms, demersal-pelagic ...

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.

Putative fishery-induced changes in biomass and population size structures of demersal deep-sea fishes in ICES Sub-area VII, Northeast Atlantic Ocean [PDF]

, 2013
A time series from 1977–1989 and 2000–2002 of scientific trawl surveys in the Porcupine Seabight and adjacent abyssal plain of the NE Atlantic was analysed to assess changes in demersal fish biomass and length frequency.
