Pineal organs in deep demersal fish
Cell and Tissue Research, 2002We studied ten species of demersal fish from depths of 1500-4800 m, i.e. regions of the abyss outside the reach of sunlight. A pineal window in the skin and/or the skull, often found in mesopelagic fish, was never observed in demersal specimens. Nine species had a well-developed pineal organ, with light- and electron-microscopic features, well known in

New Zealand Demersal Fish Assemblages
Environmental Biology of Fishes, 2002Demersal fish assemblages in the New Zealand Exclusive Economic Zone were identified using presence–absence data from 19 215 bottom trawl tows made over a 37-year period. The dataset spanned latitudes 34–54°S and depths of 4–1500 m. A total of 123 taxa occurred in more than 1% of the tows (121 fish and 2 squid).

Brain Areas in Abyssal Demersal Fishes
Brain, Behavior and Evolution, 2001Four areas of the brain which receive primary projections from chemical senses ([1] olfactory bulb, [2] gustatory area including facial and vagal lobes), the eye ([3] optic tectum), and mechanosensory, and-hair-cell based systems i.e. the lateral line, vestibular and auditory systems ([4] trigeminal and octavolateral regions) have been studied and ...

The mobilisation of sediment by demersal otter trawls
Marine Pollution Bulletin, 2011The mobilisation of sediment by towed demersal fishing gears has been related to the release of nutrients, benthic infaunal mortality and the resuspension of phytoplankton cysts and copepod eggs. Hence, to understand the broader environmental and ecological implications of demersal fishing, it is important to be able to estimate accurately the amount ...

Demersal fish in Delaware coastal waters
Journal of Natural History, 1980Summary During 1973–74, demersal fish were sampled seasonally by otter trawl from two inshore sites on the Delaware Atlantic Coast. A total of 2400 fish was taken at both sites. Of the 33 species collected, 19 were common to both sites. Urophycis chuss accounted for 38·9% of the total catch at the Cape Henlopen site and Prionotus carolinus comprised 18·
