Distribution pattern of macrozooplankton along the 140°E meridian in the Southern Ocean during austral summer 2002 and 2003

Antarctic Record, 2008
Field surveys were conducted along 140°E in the Southern Ocean north of Terre Adelie during three cruises: the KH cruise by RV Hakuho Maru, and TC1 and TC2 cruises by RV Tangaroa during the austral summers of 2002 and 2003.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, Volume 2026, Issue 5, May 2026.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Dynamical analysis of the net and the otter-boards in a midwater trawl system.

NIPPON SUISAN GAKKAISHI, 1991
In order to obtain more knowledge about the control of a midwater trawl system, three electronic instruments were produced by way of traial to measure the motions of both the otter-boards and net under trawling operations with a full-scale net. These devices were used on the sampling trawl experiment.

Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the tropical and the subtropical Atlantic representative of different water bodies (NE Brazil shelf,

Characterizing pelagic pair trawl partnerships using coordination metrics and behavior classification in the Black Sea

Ecological Informatics
Pelagic pair trawling involves two vessels towing a single midwater net in coordinated motion to target schooling pelagic species. Monitoring and distinguishing pair-trawl operations remain challenging for fisheries management, particularly when analyses

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

Frontiers 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.

One-boat midwater trawling with unequal panelled trawl

, 1983
Results of the comparative efficiency studies with 10.5 m equal panelled and 10.3 m unequal panelled midwater trawls operated from 10.9 m wooden trawler are presented. Out of the two nets, the latter proved to be relatively good for the capture of off bottom and column fishes like pomfrets, seer, lactarius, catfish, silver bar, ribbon fish and an ...

Biological characterization of a mid‐water salinity maximum intrusion over the Northeast US Shelf

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Salinity maximum intrusions, subsurface layers of anomalously salty and warm continental slope water moving onto the continental shelf along the thermocline, are recurring features over the Northeast US Shelf and represent an important cross‐shelf exchange mechanism.

Krill of the Ross Sea: distribution, abundance and demography of Euphausia superba and Euphausia crystallorophias during the Italian Antarctic Expedition (January-February 2000)

Scientia Marina, 2002
Net samples data from the 15th Italian Antarctic Oceanographic Cruise (Jan-Feb 2000) were analysed to obtain a general picture of the summer distribution pattern, abundance and demography of krill in the western Ross Sea (Antarctica).

Bottlenose dolphin reliance on trawlers in prey-depleted Adriatic Sea regions

Frontiers in Mammal Science
The Adriatic Sea is one of the areas most exposed to trawling worldwide. The common bottlenose dolphin Tursiops truncatus—the only cetacean species regularly present in the northern and central portions of the basin—is known to forage and scavenge behind
