Microplastic interactions with north atlantic mesopelagic fish [PDF]

open access: yes, 2015
Microplastics in the marine environment are well documented, and interactions with marine biota have been described worldwide. However, interactions with vertically migrating fish are poorly understood.

Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

open access: yesJournal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

Implications for the mesopelagic microbial gardening hypothesis as determined by experimental fragmentation of Antarctic krill fecal pellets

open access: yesEcology and Evolution, 2021
Detritivores need to upgrade their food to increase its nutritional value. One method is to fragment detritus promoting the colonization of nutrient‐rich microbes, which consumers then ingest along with the detritus; so‐called microbial gardening ...

Mesopelagic Fish Protein Hydrolysates and Extracts: A Source of Novel Anti-Hypertensive and Anti-Diabetic Peptides

open access: yesFrontiers in Marine Science, 2021
The abundance of fish and zooplankton (1 × 109 tons to 7 × 1010 tons) in the mesopelagic zone of the ocean is a source of novel raw materials that provides opportunities for sustainable new product development.

Stable Isotope Composition of Skin Layers Confirms Trophic Differentiation of Baird's and Sato's Beaked Whales (Berardius spp.) in the Western North Pacific

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale Closely related whale species can appear similar yet occupy distinct ecological niches. Sato's beaked whale (Berardius minimus) was only recently recognized as a separate species and was previously grouped with Baird's beaked whale (Berardius bairdii), limiting our understanding of their ecological differences.

Assessing Zooplankton Communities' Influence on Particulate Organic Carbon Concentration

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Zooplankton play a key role in setting the particulate organic carbon (POC) distribution in the ocean, but this role remains poorly quantified on large scales due to the complexity of zooplankton ecosystems and the sparsity and variability of observations.

Composition, distribution, and life history strategies of mesopelagic fauna in a changing Arctic Ocean [PDF]

open access: yes, 2023
Micronekton and zooplankton inhabit the mesopelagic zone (200-1,000 m depth) which represents a unique environment in the global ocean where low-light levels structure predator-prey interactions.

Finding mesopelagic prey in a changing Southern Ocean [PDF]

open access: yes, 2019
International audienceMesopelagic fish and squid occupy ocean depths extending below the photic zone and their verticalmigrations represent a massive pathway moving energy and carbon through the water column.Their spatio-temporal distribution is however,

Copepod community structure and physiological rates shape the biological pump during early North Atlantic spring bloom

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Zooplankton plays an important role in the biological carbon pump, and zooplankton biomass and community structure can have a large influence on the sedimentation/remineralization balance of the water column. We investigated the potential effects of zooplankton community structure and eco‐physiology on the export and attenuation of vertical ...

Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest “unsafe” levels of oxygen loss with far‐reaching impacts

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Oxygen is critical for nearly all life on Earth, including aquatic species that breathe dissolved oxygen in both freshwater and marine systems. The rapid, global, and anthropogenic loss of dissolved oxygen known as “aquatic deoxygenation” threatens life in these environments, the human communities that depend on them, and Earth system ...
