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

Assessment demersal fish stocks Mauritania [PDF]
, 2006 The RIVO project "Assessment of demersal fish stocks in Mauritania" was commissioned by the Ministry of Foreign Affairs of The Netherlands to produce information on the state of the demersal fish stocks (species that live near the bottom) in Mauritania, in particular octopus and shrimps.

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.

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).

Foods, 2020 Fish is a major part of the Bangladeshi diet, but data on the nutrient composition of marine fish species are sparse. Mesopelagic fish may be a new potential resource of food and nutrients; however, nutrient composition data are lacking.

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 ...

Fatty Acid Profile, Lipid and Cholesterol Content, and Nutritional Lipid Quality of Seven Fish Species from the Persian Gulf [PDF]
Journal of Fasting and Health, 2021 A total of seven fish species from the Persian Gulf, belonging to three pelagic, benthopelagic, and demersal habitat groups were evaluated for the fatty acid composition, lipid and cholesterol contents, and nutritional lipid quality characteristics of ...

Changes in the structure and functionof the North Sea fish foodweb, 1973-2000, and the impacts of fishing and climate [PDF]
, 2005 North Sea environmental and biological data were analysed to examine 30-year changes in production and consumption in the fish food web. The analysis revealed that the demand for secondary production placed on the ecosystem by fish declined from ...

Habitat specialization in tropical continental shelf demersal fish assemblages. [PDF]
PLoS ONE, 2012 The implications of shallow water impacts such as fishing and climate change on fish assemblages are generally considered in isolation from the distribution and abundance of these fish assemblages in adjacent deeper waters.

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.
