Economic viability of a large vessel mesopelagic fishery under ecological uncertainty

Frontiers in Marine Science, 2023
Motivated by the global rise in demand for marine products, there is increased interest in exploitation of the mesopelagic zone. However, the feasibility of this potential fishery remains uncertain, partly due to limited biological data and knowledge on ...

Data_Sheet_1_Spatial Distribution and Abundance of Mesopelagic Fish Biomass in the Mediterranean Sea.DOCX [PDF]

, 2023
Mesopelagic fish, being in the middle of the trophic web, are important key species for the marine environment; yet limited knowledge exists about their biology and abundance.

Abundance of mesopelagic fish collected at different layers of the water column around the Iberian Peninsula [PDF]

, 2022
This file contains data on number of mesopelagic fish collected during the CSIC-SUMMER survey carried out in October 2020 in five zones around the Iberian Peninsula: Balears and Alboran in the western Mediterranean, and Cadiz, Lisboa and Galicia.

Bridging the gap from ocean models to population dynamics of large marine predators: A model of mid-trophic functional groups [PDF]

, 2009
The modeling of mid-trophic organisms of the pelagic ecosystem is a critical step in linking the coupled physical–biogeochemical models to population dynamics of large pelagic predators. Here, we provide an example of a modeling approach with definitions

Energy density of mesopelagic fishes from the Atlantic Ocean

Journal of Fish Biology, 2023
AbstractMesopelagic fishes play a central role in marine food webs linking primary consumers to top predators. In this study, measures of direct calorimetry were used to analyse the energy density (ED) of 34 mesopelagic species collected at 12 stations in the equatorial and tropical Atlantic.

Mesopelagic fishes dominate otolith record of past two millennia in the Santa Barbara Basin

Nature Communications, 2019
Little is known about the long-term dynamics of mesopelagic fish despite their large contribution to total fish biomass. Here, the authors analyze the Santa Barbara Basin otolith record and suggest that mesopelagic fish populations were large but ...

Increased prokaryotic diversity in the Red Sea deep scattering layer

Environmental Microbiome, 2023
Background The diel vertical migration (DVM) of fish provides an active transport of labile dissolved organic matter (DOM) to the deep ocean, fueling the metabolism of heterotrophic bacteria and archaea.

Variation in mesopelagic fish community composition and structure between Mediterranean and Atlantic waters around the Iberian Peninsula

Frontiers in Marine Science, 2022
Mesopelagic fish populations are characterised by high species richness and abundance, and have been identified as important contributors to the active carbon fluxes in the open ocean. We report variability in communities of mesopelagic fish between five

Three‐dimensional swimming behavior and activity of a mesopelagic fish

Limnology and Oceanography, 2022
AbstractKnowledge of the three‐dimensional behavior and activity patterns of mesopelagic fishes is crucial for understanding their role in ecological and biogeochemical processes in the ocean. We here show that the use of submerged stationary echosounders enables detailed analysis of three‐dimensional swimming behavior of small mesopelagic fishes in ...

Seasonal dynamics of the vertical migration behaviour of mesopelagic fish [PDF]

, 2010
This thesis focuses on the behavioural dynamics of mesopelagic fish in a fjordic environment. Acoustic data recorded with a stationary echosounder was used to primarily investigate the diel vertical migration behaviour of the mesopelagic fish Maurolicus ...
