The large estimates of mesopelagic fish biomass have fuelled harvesting interests in the relatively untouched ocean's twilight zone. Mueller's pearlside, one most abundant species inhabiting north Atlantic layer, is a candidate to such fisheries despite its enormous ecological importance and insufficient knowledge about population genetic structure. To shed light on latter, 863 individuals sampled across North Mediterranean were genotyped using 170 genome-wide SNPs. Analyses revealed...
ABSTRACT Fishes inhabiting the mesopelagic zone of world's oceans are estimated to account for majority fish biomass. They have recently attracted new attention because they part biological carbon pump and been reconsidered as a contribution food security. Hence, there is an urgent need understand how environmental conditions species interactions shape their assemblages, contribute functioning marine ecosystems. Trait‐based approaches valuable addressing these types questions. However,...
We describe a method to allow acoustic sampling at depths not reachable by the higher frequencies of ship hull-mounted echosounders and observe abundance behaviour individual organisms in front trawls. A self-contained scientific echosounder with 120 kHz transducer was mounted forward-facing on headline macrozooplankton trawl that obliquely towed from 0 1000 m depth, investigate mesopelagic fauna. With use echosounder, we were able estimate organism densities trawl, vertical profiles target...
The glacier lanternfish Benthosema glaciale is a key myctophid with wide distribution in the northern Atlantic. It species that has strong vertical migration capacity and have potential to move between surface waters mesopelagic depths diel cycle (DVM), mainly depending on ambient light conditions. We investigated feeding ecology of B. across Norwegian, Iceland, Irminger Labrador Sea basins. An important component diet was various types calanoid copepods, but some additional variability deep...
Abstract The influence of oceanographic variables on assemblages meso- and bathypelagic fish was investigated along a Northeastern Atlantic Ocean transect (Cape Verde to the Bay Biscay) during May 2019. Fish were collected using macrozooplankton trawl daylight hours at ten stations. Along transect, 17 hydrographic stations also performed with CTD (Conductivity, Temperature, Depth). A total 130 taxa identified. dominant family Gonostomatidae, four species (Cyclothone braueri, Cyclothone...
It is important to understand the population dynamics of myctophids for a better understanding functioning ecosystem. In this work, age-based demography parameters glacier lanternfish (Benthosema glaciale (Reinhardt, 1837)) were calculated. This study was based on 1213 individuals collected in Flemish Cap during June–July 2008 and 2010. Ages estimated from counts annuli whole otolith. A strong relationship found between both diameters otolith fish length, weight increment number. Males...
This study investigates the large-scale distribution patterns of acoustic scattering layers and micronekton density across Northeast Atlantic Ocean during daylight hours. A research cruise on board R/V "Kronprins Haakon" was conducted May 2019 from Cape Verde to Bay Biscay. Hydrological data were obtained at 20 conductivity-temperature-depth sensor (CTD) stations. To estimate densities in front trawl, an autonomous echo sounder (120 or 200 kHz) headrope macroplankton trawl used. Acoustic...
Ageing using otolith microstructure is based on the assumption that growth increments are deposited daily. Individuals of glacier lanternfish (Benthosema glaciale) were collected in Flemish Cap (north-west Atlantic) during June–July 2010. A total 44 individuals (ranging from 28 to 49mm standard length; <2 years old) selected analyse light microscopy order assess reliability use microincrements infer true age this species. Three distinct zones distinguished: larval zone, postlarval zone...
Abstract A new acoustic approach to estimate the mass of individual gas-bearing fish at their resident depth more than 400 m was tested on Cyclothone spp.. are small and slender, possibly numerically underestimated globally as individuals can pass through trawl meshes. towed instrumented platform used one sampling station in Northeast Atlantic, where spp. dominated net catches, measure situ wideband target strength (TS) spectra, i.e. scattering response a given organism (”target”) over...
The genus Pseudoterranova includes parasite species of cetaceans and pinnipeds. third stage larva (L3) seal-infecting occur in second intermediate or paratenic fish hosts mainly neritic waters. This study firstly describes a L3 from meso/bathypelagic fishes off Macaronesia. L3s were morphologically genetically studied by light microscopy sequencing the mtDNA cox2 entire ITS rDNA genes. Bayesian inferences performed with sequences larvae selected GenBank. nematode molecularly identified as...
Mesopelagic organisms play an important role in the vertical carbon flux through diel migrations. The mesopelagic fauna of three NE Atlantic seamounts (Gorringe Bank, Josephine and Seine) surrounding oceanic waters were sampled. Echogram scrutiny suggests a migration fauna. Muggiaea atlantica Meganyctiphanes norvegica caught at almost every station thus, appeared to be ubiquitous. Several taxa only open stations (e.g. Lampanyctus alatus, Deosergestes corniculum Acanthephyra purpurea) whereas...
