Diel vertical migrations of bathypelagic perch fry
Journal of Fish Biology, 2005The behaviour of young‐of‐the‐year (YOY) perchPerca fluviatilisas a dominant species in the assemblage of fry in the pelagic of Slapy Reservoir (Czech Republic), was studied during late May and mid‐June 2002 using acoustic methods and complementary net catches.

Reproduction of meso- and bathypelagic chaetognaths in the genus Eukrohnia
Marine Biology, 1982Reproduction of meso- and bathypelagic chaetognaths, a major group of zooplankton and hermaphroditic animals, became clear after the microscopic examination of samples collected from the Pacific Subarctic Water. Species of the genus Eukrohnia carry their developing eggs in two marsupial sacs, one on each side, and the young are retained in these ...

The biology of bathypelagic organisms, especially Crustacea
Deep Sea Research and Oceanographic Abstracts, 1972Abstract An examination is made of the body sizes of species of euphasiidss, mysids, copepods and chaetognaths living in different bathymetric zones. The maximum body size of each species is used as a measure of its potential for growth in size. Bathypelagic euphausiids and mysids are shown to possess a much greater potential for attaining greater ...

Composition of the swim-bladder gas in bathypelagic fishes
Deep Sea Research (1953), 1957Abstract Measurements were made of swim-bladder size and gas composition on pelagic fish in the eastern Pacific. The physiological problem of vertical migration with a swim-bladder is discussed. It is concluded that some gas-containing fish migrate vertically but that net-collecting data is too fragmentary to determine if such fish are primarily ...

Remarkable heterogeneity in meso- and bathypelagic bacterioplankton assemblage composition
Limnology and Oceanography, 2006We investigated meso- to bathypelagic (500–3,000 m) bacterioplankton assemblage composition at 19 locations in the North Atlantic Ocean beneath the offshore Amazon River plume, in the North Pacific Ocean near the Hawaiian archipelago, at the San Pedro Ocean Time Series (SPOTS) station off southern California, and in the Coral Sea off eastern Australia ...

Function of extra-ocular photoreceptors in bathypelagic cephalopods
Deep Sea Research and Oceanographic Abstracts, 1972The photosensitive vesicles of four species of bathypelagic cephalopods are examined. In species of Bathyteuthis the vesicles appear to function in the detection of bioluminescent light from organisms located outside the visual field. In Galiteuthis phyllura the vesicles may function both in detecting bioluminescent light and down-welling surface light.

Distribution and Diversity of Microbial Eukaryotes in Bathypelagic Waters of the South China Sea
Journal of Eukaryotic Microbiology, 2016AbstractLittle is known about the biodiversity of microbial eukaryotes in the South China Sea, especially in waters at bathyal depths. Here, we employed SSU rDNA gene sequencing to reveal the diversity and community structure across depth and distance gradients in the South China Sea. Vertically, the highest alpha diversity was found at 75‐m depth. The

Geographic distribution of the bathypelagic genus paraeuchaeta (Copepoda, Calanoida)
Hydrobiologia, 1994The geographic distribution of the bathypelagic calanoid genus Paraeuchaeta was investigated by examining midwater trawl and plankton net samples collected mostly from depths exceeding 1000 m throughout the world’s oceans. Of the 81 species referred to Paraeuchaeta,the geographic ranges of about 50 species could be defined with reasonable certainty ...
