Pineal organs in deep demersal fish

Cell and Tissue Research, 2002
We 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, 2021
Information 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, 2002
Demersal 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).

Spatial contraction of demersal fish populations in a large marine ecosystem

Journal of Biogeography, 2019
The interdependencies between trophic interactions, environmental factors and anthropogenic forcing determine how species distributions change over time. Large changes in species distributions have occurred as a result of climate change. The objective of

Brain Areas in Abyssal Demersal Fishes

Brain, Behavior and Evolution, 2001
Four 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 ...

Risk versus reward: interactions, depredation rates, and bycatch mitigation of dolphins in demersal fish trawls

Canadian Journal of Fisheries and Aquatic Sciences, 2018
An improved understanding of interaction dynamics between dolphins and trawlers is essential for improving bycatch mitigation strategies. In-situ observations using video at increasing distances from the net opening during 50 commercial fish trawls ...

Demersal fish in Delaware coastal waters

Journal of Natural History, 1980
Summary 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·

Recent advances of marine ornamental fish larviculture: broodstock reproduction, live prey and feeding regimes, and comparison between demersal and pelagic spawners

Reviews in Aquaculture, 2019
Marine ornamental fish are a key component of the multimillion‐dollar marine aquarium trade industry, a controversial industry due to current heavy reliance on wild‐collected specimens. Aquaculture of marine ornamental fish is considered as a sustainable

Feeding biomechanics of five demersal Antarctic fishes

Polar Biology, 2014
There 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 ...
