Ecological InformaticsPelagic 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

A Computer Simulation for the Net Position Control of Midwater Trawl System.
NIPPON SUISAN GAKKAISHI, 2001 中層トロール漁法では, 常に目標魚群に対して網位置を迅速に制御しなければならない。本論文では, 著者らが提案した中層トロールシステムの運動特性を求めるモデルに基づいて, 東京水産大学の練習船神鷹丸に装備されている中層トロール網を例とした網位置の制御シミュレーションを行った。ワープ長または船速を制御入力とした網位置の動態は海上実験で捉えた現象をよく再現した。シミュレーションの結果を実操業に応用する例として, あるワープ長と船速における網位置から, ワープ長と船速を調整することで, 探知された目標魚群の位置へ網をより迅速に制御する方法を示した。また, 探索曳網中の初期ワープ長による制御出力(水深および制御時間)への影響が小さいことも確かめられた ...

Fisheries Oceanography, Volume 35, Issue 2, Page 285-296, March 2026.ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

Flytetrål tilbake i torskefisket etter 30 år : Midwater trawl returns to the cod fishery
, 2008 After thirty years of prohibition, the midwater trawl may once again become an alternative to the bottom trawl in the cod, haddock and saithe fisheries. A midwater trawl has no impact on the seabed and requires less energy to operate than a bottom trawl.

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