Trophic Structure and Sources of Variation Influencing the Stable Isotope Signatures of Meso- and Bathypelagic Micronekton Fishes

open access: yesFrontiers in Marine Science, 2020
To better understand spatiotemporal variation in the trophic structure of deep-pelagic species, we examined the isotope values of particulate organic matter (POM) (isotopic baseline) and seven deep-pelagic fishes with similar diet compositions but ...

Seasonal oceanography from physics to micronekton in the south-west Pacific [PDF]

open access: yesDeep Sea Research Part II: Topical Studies in Oceanography, 2015
Tuna catches represent a major economic and food source in the Pacific Ocean, yet are highly variable. This variability in tuna catches remains poorly explained. The relationships between the distributions of tuna and their forage (micronekton) have been mostly derived from model estimates.

Microbial and Metazoan Activity in Monterey Bay, CA Recorded in Nitrogen Isotope Ratios of Sinking and Suspended Particles

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Particulate organic matter supports pelagic food webs, and the activity of these food webs attenuates the flux of carbon into the ocean interior. Understanding the extent to which microbial and metazoan heterotrophs influence particle dynamics is essential to describing the biological carbon pump and nutrient delivery to deep ecosystems.

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

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.

Major Shifts in Pelagic Micronekton and Macrozooplankton Community Structure in an Upwelling Ecosystem Related to an Unprecedented Marine Heatwave

open access: yesFrontiers in Marine Science, 2019
The community structure of pelagic zooplankton and micronekton may be a sensitive indicator of changes in environmental conditions within the California Current ecosystem.

Tracking Long‐Term Trends in Sockeye Salmon (Oncorhynchus nerka) Population Dynamics Using Sterol and Stanol Biomarkers in Lake Sediments

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract We analyzed biomarkers, including sterols, stanols, and δ15N, in sediment cores from lakes with well‐documented sockeye salmon return histories. Our goal was to improve estimates of past changes in salmon escapement, that is, the population that return to their freshwater nursery lakes, inferred using sediment biogeochemical markers ...

Acoustic Assessment of the Micronekton Community on the Chatham Rise, New Zealand, Using a Semi-Automated Approach

open access: yesFrontiers in Marine Science, 2019
Micronekton are a key component of the pelagic food web of the Chatham Rise east of New Zealand. The Chatham Rise is an important fishing area for hoki (Macruronus novaezelandiae), New Zealand’s largest finfish fishery, and a predator on mesopelagic fish.

Highly mobile pelagic species co‐occur with fine‐scale ocean fronts

open access: yesLimnology and Oceanography, Volume 70, Issue 7, Page 1901-1912, July 2025.
Abstract Coastal areas are an important source of food and a valuable tourism asset for communities, but also highly dynamic and heterogeneous environments. Understanding how marine species respond to the variability of their habitat is essential to sustainably manage coastal resources.

Zooplancton et micronecton dans la région du Dôme d'Angola en février-mars 1971 et rélation avec les thons [PDF]

open access: yes, 1973
Diurnal variations and geographic distribution of zooplankton and micronekton are studied in the Angola Dome. The small zooplankton species (Copepodids, Copepods, Amphipods, Ostracods, Chaetognaths, etc.) undertake vertical migrations within a 100 m ...
