Linking oceanic variability, euphausiid hotspot persistence, and marine predator distribution along Canada's west coast. [PDF]

Ecol Appl
Abstract Understanding patterns of habitat use across trophic levels and the physical drivers of multispecies aggregations is essential to inform ecosystem‐based management. To achieve this, we quantified the spatial distribution and co‐occurrence of hotspots (defined using the Getis‐Ord statistic) for euphausiids and nine of their commercially ...

Modern specialized fishery of sea fish in the western Bering Sea

Известия ТИНРО, 2021
The shelf and continental slope of the western Bering Sea, being among the most productive areas of the Far-Eastern Seas of Russia, became exploited by commercial fishery half a century ago, after introduction of 200-mile exclusive economic zones in 1977

Flume Tank Evaluation on the Effect of Liners on the Physical Performance of the Antarctic Krill Trawl

Frontiers in Marine Science, 2022
The Antarctic krill (Euphausia superba) is one of the most abundant resources in the ocean, which provides food for several important species in the Antarctic Ocean, and is targeted commercially by humans for many decades.

Estimating the sampling efficiencies of a framed midwater trawl and ring net for zooplankton using an acoustic method

Journal of Marine Science and Technology, 2021
It is well known that there is bias using different sampling gear, such as a framed midwater trawl (FMT) and a ring net, when measuring the density and length distribution of target species.

Field experiment on static characteristics of midwater trawl system. [PDF]

NIPPON SUISAN GAKKAISHI, 1991
A field experiment was conducted by FRV “Shinyo-maru” belonging to Tokyo University of Fisheries in order to make detailed measurements on operational characteristics of a mid-water trawl system. Time series data describing the net geometry and the towing loads occurring during hauls were measured by SCANMAR system (acoustic spreadmeter and netsonde ...

Some data about distribution of fry saffron cod Eleginus gracilis and walleye pollock Theragra chalcogramma on the west coast of Кamchatka and species composition in the catches of midwater trawl with a small-meshed insertion

The researches of the aquatic biological resources of Kamchatka and of the north-west part of the Pacific Ocean, 2021
Data of trawl surveys for the period 2010–2017 revealed distribution of fry saffron cod in vicinity of river outlets, while juvenile walleye pollock was dictributed either near the shore or over the deepwater area in the southern part of shelf.

Three Distinct Views of Deep Pelagic Community Composition Based on Complementary Sampling Approaches

Frontiers in Marine Science, 2022
Our perception of deep-sea communities has evolved as various sampling approaches have captured different components of deep-sea habitats. We sampled midwater zooplankton assemblages in Monterey Bay, California to quantify community composition ...
