Demersal and larval fish assemblages in the Chukchi Sea
Deep-Sea Research Part II: Topical Studies in Oceanography, 2010A multidisciplinary research cruise was conducted in the Chukchi Sea in summer 2004 during which we investigated assemblages of small demersal fishes and ichthyoplankton and the water masses associated with these assemblages. This study establishes a baseline of 30 demersal fish and 25 ichthyoplankton taxa in US and Russian waters of the Chukchi Sea ...

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 ...

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 ...

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·

Are Larvae of Demersal Fishes Plankton or Nekton?
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 ...

Deep demersal fishes in the Canary Islands
2023Some remarks about deep-sea demersal species of fishes captured in fishery prospections from La Gomera, Gran Canaria and Tenerife (Canary Islands) between 300-2500 m depth are given. Long-lines and experimental traps were used during the cruises. Twenty-five species werre collected.

Reproductive Strategies of Demersal and Pelagic Spawning Fish
Canadian Journal of Fisheries and Aquatic Sciences, 1984The spawning tactic of herring (Clupea harengus) wherein batches of eggs are deposited leading to a succession of larval cohorts is elaborated. We found the time interval between cohorts to be a function of larval growth rate as well as larval mouth size.

Food of predatory demersal fish in Hauraki Gulf
New Zealand Journal of Marine and Freshwater Research, 1970Summary In 1965–66, the feeding relationships of snapper Chrysophrys auratus (Forster), trevally Caranx lutescens Richardson, red gurnard Chelidonichthys kumu Lesson and Garnot, horse mackerel
