Trophic-Mediated Pelagic Habitat Structuring and Partitioning by Sympatric Elasmobranchs

Frontiers in Marine Science, 2022
Pelagic elasmobranchs are key elements of oceanic ecosystems and must be preserved if marine trophic networks are to be kept in balance. Yet, they face intense fishing pressure that has been threatening their populations worldwide.

First insights into oceanic manta ray movements in Japan using satellite telemetry

Journal of Fish Biology, EarlyView.
Abstract Japanese waters represent the northern distributional limit of the western Pacific distribution of the oceanic manta ray (Mobula birostris), yet movement ecology in this region remains poorly understood. We report movements of the first satellite‐tagged individual in Japan.

The protist community traces seasonality and mesoscale hydrographic features in the oligotrophic Sargasso Sea

Frontiers in Marine Science, 2022
Protists represent the majority of the eukaryotic diversity in the oceans. They have different functions in the marine food web, playing essential roles in the biogeochemical cycles.

Body size, functional form and environmental correlates of maximum longevity in marine‐occurring fishes

Journal of Fish Biology, EarlyView.
Abstract Maximum longevity varies widely among marine‐occurring fishes, but the form of its relationship with body size and the contribution of broad environmental gradients remain uncertain. We analysed 757 species, using maximum length as the primary size metric and completed mass only in sensitivity analyses.

Size selectivity of Muller's pearlside (Maurolicus muelleri), glacier lanternfish (Benthosema glaciale) and krill in trawls targeting the mesopelagic fish [PDF]

The growing interest in harvesting mesopelagic fish increases the need for knowledge about trawl designs with high catch efficiency. Limited swimming ability of small mesopelagic species makes it important to consider potential net selectivity along the ...

Controls over Ocean Mesopelagic Interior Carbon Storage (COMICS): fieldwork, synthesis and modelling efforts

Frontiers in Marine Science, 2016
The ocean’s biological carbon pump plays a central role in regulating atmospheric CO2 levels. In particular, the depth at which sinking organic carbon is broken down and respired in the mesopelagic zone is critical, with deeper remineralisation resulting

Accounting for Uncertainties in Biodiversity Estimations: A New Methodology and Its Application to the Mesopelagic Sound Scattering Layer of the High Arctic

Frontiers in Ecology and Evolution, 2022
Measures of biological diversity (biodiversity) are important for monitoring the state of ecosystems. Several indices and methods are used to describe biodiversity from field observations.

Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Can mesopelagic mixed layers be used as feed sources for salmon aquaculture? [PDF]

, 2019
Salmon aquaculture is in great need of good quality balanced protein and lipid sources, particularly marine omega-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFA), to sustain a further development of the industry.

Global length–weight relationships of deep‐pelagic fishes: Coverage, biases and variability

Journal of Fish Biology, EarlyView.
Abstract Length–weight relationships (LWRs) are morphometric tools that allow body mass to be estimated from fish length, providing input for fisheries, ecological and biodiversity studies. For deep‐pelagic fishes, however, LWR data remain fragmented and unavailable for most species.
