Acoustical patchiness of mesopelagic micronekton

open access: yesDeep Sea Research Part B. Oceanographic Literature Review, 1985
Patterns of acoustical scattering in both depth and horizontal extent were analyzed to estimate the spatial and temporal scales of variability in biomass of mesopelagic sound scatterers, principally micronekton.

Geographical and species differences of fatty acid components of small pelagic fishes, micronekton, and squids in the northwestern pacific [PDF]

open access: yesAquaculture and Fisheries
Geographical and species differences in fatty acid composition were evaluated among 546 specimens of small pelagic fish, micronekton, and squid in the Northwestern Pacific.

Stable isotope patterns in micronekton from the Mozambique Channel [PDF]

open access: yesDeep Sea Research Part II: Topical Studies in Oceanography, 2014
Abstract We measured the stable carbon (δ 13 C) and nitrogen (δ 15 N) isotopic composition of tissues of micronektonic organisms (fishes, squids, crustaceans and gelatinous organisms) collected in the Mozambique Channel during two scientific cruises in 2008 and 2009. The oceanic circulation in the Mozambique Channel is dominated by mesoscale cyclonic

The community structure of micronekton from an oceanic eddy [PDF]

open access: yes, 1985
A mesoscale feature of the ocean exists on a spatial scale of tens to hundreds of kilometres and a temporal scale of one to three years. The size of micronekton (10 mm to 100 mm), their sustained swimming speed (at least 5 km d-1) and their lifespan (typically one to three years) recommend them for study in relation to mesoscale oceanographic features.

Species distribution models describe spatial variability in mesopelagic fish abundance in the Southern Ocean

open access: yesFrontiers in Marine Science, 2023
IntroductionMesopelagic fishes play a central role in the transfer of energy through open-ocean food webs, particularly in the Southern Ocean where they are both important predators of zooplankton and a key prey group for many higher predators.

VERDA: A Multisampler Tool for Mesopelagic Nets

open access: yesJournal of Marine Science and Engineering, 2023
Different types and systems to discriminate plankton samples at different strata in the water column have been developed in recent decades. For sampling at sufficient depth, opening and closing zooplankton multinets are ideal because there is no ...

Fine-scale vertical structure of sound-scattering layers over an east border upwelling system and its relationship to pelagic habitat characteristics [PDF]

open access: yesOcean Science, 2020
Understanding the relationship between sound-scattering layers (SSLs) and pelagic habitat characteristics is a substantial step to apprehend ecosystem dynamics. SSLs are detected on echo sounders representing aggregated marine pelagic organisms.

Swimbladder properties of Cyclothone spp. in the northeast Atlantic Ocean and the Western Mediterranean Sea

open access: yesFrontiers in Marine Science, 2023
Non-migratory bristlemouth fishes (Cyclothone spp.) are the most abundant vertebrates on Earth and play an important role in the biological carbon pump by remineralizing organic carbon in deep ecosystems.

Characterizing the Sound-Scattering Layer and Its Environmental Drivers in the North Equatorial Current of the Central and Western Pacific Ocean

open access: yesJournal of Marine Science and Engineering, 2023
Acoustic technology is an essential tool for detecting marine biological resources and has been widely used in sound-scattering layer (SSL) research. The North Equatorial Current (NEC) warm pool region of the Central and Western Pacific Ocean has a vast ...

Optimization of a micronekton model with acoustic data [PDF]

open access: yesICES Journal of Marine Science, 2014
Abstract In the pelagic foodweb, micronekton at the mid-trophic level (MTL) are one of the lesser known components of the ocean ecosystem despite being a major driver of the spatial dynamics of their predators, of which many are exploited species (e.g. tunas).
