Functional and Trophic Structuring of Micronektonic Fishes in the Northeast Atlantic [PDF]

Ecology and Evolution
In pelagic ecosystems, sharp vertical gradients in resources and environmental conditions structure species adaptations, interactions and community assembly. Yet, the ecological mechanisms underlying these patterns remain poorly resolved.

Turbulent flow interacting with flexible trawl net structure including simulation catch in flume tank [PDF]

Scientific Reports, 2023
The interaction between fluid and the midwater trawl with stocked catches is extremely complex, but essential to improve the understanding of the drag force acting on the trawl, the behavior of the fishing structure during a trawling process, and to ...

Examining engineering performance of midwater trawl with different horizontal spread ratio, floatage, and weight parameters: A case study of model net for Antarctic krill fisheries

International Journal of Naval Architecture and Ocean Engineering, 2022
It is necessary to investigate the effectiveness of the midwater trawl in reducing fuel consumption and increasing catch performance for the development and improvement of the Antarctic krill fisheries.

Effect of Cutting Ratio and Catch on Drag Characteristics and Fluttering Motions of Midwater Trawl Codend

Journal of Marine Science and Engineering, 2021
The codend of a trawl net is the rearmost and crucial part of the net for selective fish catch and juvenile escape. To ensure efficient and sustainable midwater trawl fisheries, it is essential to better understand the drag characteristics and fluttering

Catch Losses and Reduction of Bycatch for Jellyfish Using Marine Mammal Bycatch Reduction Devices in Midwater Trawl Gear

Fishes
The National Institute of Fisheries Science in Korea is developing marine mammal bycatch reduction devices (BRDs) for midwater trawl gear. In this study, we tested two BRD-type guide nets (inclined net panel) with 30° and 45° tilt angles to prevent ...

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae. [PDF]

J Fish Biol
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Identification of three cephalopods from the Iranian waters of the Gulf of Oman (Continental shelf area) [PDF]

Iranian Journal of Animal Biosystematics, 2021
This study aimed to find new species of cephalopods in the Iranian waters of the Gulf of Oman. Two species of Oegopsida (Abralia steindachneri Weindl, 1912 and Joubiniteuthis portieri (Joubin, 1916)) and also one species of Sepiida (Sepia omani Adam ...

A method to determine patterns for changing parameters of the rope-net shell of midwater trawl along its length

Известия ТИНРО, 2023
A technique for designing the rope-net shell of midwater trawl is described on example of the trawl Sirius Shelf project AS 11.012.000 designed by Aquaservice Ltd. Diagrams of the rope-net shell parameters distribution along trawl are used. The technique
