Are Larvae of Demersal Fishes Plankton or Nekton?
Advances in Marine Biology, 2006A pelagic larval stage is found in nearly all demersal marine teleost fishes, and it is during this pelagic stage that the geographic scale of dispersal is determined. Marine biologists have long made a simplifying assumption that behaviour of larvae--with the possible exception of vertical distribution--has negligible influence on larval dispersal ...

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

Essential fish habitats of demersal fish in the western Arabian Gulf
Marine Pollution Bulletin, 2021Information about habitats occupied by aquatic organisms while completing critical stages of their lives, called essential fish habitats, is crucial for their sustainability. In this work, we determine essential fish habitats (nursery and spawning grounds) of several fish species inhabiting Saudi territorial waters in the western Arabian Gulf using ...

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 ...

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·

Feeding biomechanics of five demersal Antarctic fishes
Polar Biology, 2014There is scant information available on the ecomorphology of Antarctic fishes, and especially on their feeding capabilities. We measured interspecific variation in mechanical advantage (MA), force-producing capability, and suction index for the jaws of the five dominant taxa of high-Antarctic fishes: the nototheniid Trematomus bernacchii; the zoarcids ...

Foraging Behaviour Patterns of Four Sympatric Demersal Fishes
Estuarine, Coastal and Shelf Science, 1999The trophic relationships of four sympatric demersal fish species ( Mullus barbatus , Mullus surmuletus , Pagrus pagrus and Gobius niger ) which dominate the shallow coastal areas (25–30 m) of Iraklion Bay (S Aegean, NE Mediterranean) were investigated from samples collected on a monthly basis (August 1990–August 1992).

Deepwater Demersal Fish Community Collapse in Lake Huron
Transactions of the American Fisheries Society, 2008AbstractLong‐term fish community surveys were carried out in the Michigan waters of Lake Huron using bottom trawls from 1976 to 2006. Trends in abundance indices for common species (those caught in 10% or more of trawl tows) were estimated for two periods: Early (1976‐1991) and late (1994‐2006).
