Pacific bluefin tuna (Thunnus orientalis) bycatch in the Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract A large tuna was hooked by a Japanese longline fishery in the high seas near the Republic of Namibia. This fishing ground is mainly utilized for Thunnus albacares, Thunnus obesus and Thunnus alalunga by Japanese tuna longliners. Because the tuna was larger than the common size of these species, the specimen was sampled for genetic species ...

Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

Journal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

Status of off-bottom mariculture in wave-exposed environments. Part 2. Comparative loading and motion of longline designs currently used in exposed commercial farms

Frontiers in Aquaculture
A global inventory of extractive species mariculture in wave-exposed temperate waters shows that the longline is the technology used in more than 99% of the sites (Part 1 of this review).

Quantifying post‐release behaviour of a critically endangered elasmobranch over two capture events using high‐resolution archival tag data

Journal of Fish Biology, EarlyView.
Abstract During catch‐and‐release angling, highly resident species are susceptible to multiple recapture events. Biologging offers the opportunity to study post‐release behaviour in detail; however, most studies have focused on a single capture‐release event.

DNA barcoding reveals the presence of Whitson's grenadier, Macrourus whitsoni, in sub‐Antarctic waters of South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Macrourid species constitute the main bycatch in Southern Ocean toothfish longline fisheries. We report the first confirmed record of Whitson's grenadier, Macrourus whitsoni, in the South Georgia toothfish fishery. Mitochondrial cox1 DNA barcoding confirmed its presence in bycatch samples collected around South Georgia and the northern South ...

A first record of the Smallfin Gulper Shark Centrophorus moluccensis Bleeker, 1860 (Chondrichthyes: Squaliformes: Centrophoridae) from the Andaman & Nicobar waters, Indian EEZ

Journal of Threatened Taxa, 2017
The Smallfin Gulper Shark Centrophorus moluccensis is reported for the first time from the Andaman & Nicobar waters of the Indian EEZ.  A male specimen of 785mm total length and weighing 2.34kg was landed by a motorized longliner at Burmanallah, South ...

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. While K. thyrsites has previously been identified in migratory Atlantic mackerel in the northern Northeast Atlantic Ocean,

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

Restoration Ecology, EarlyView.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.

Species’ traits and exposure as a future lens for quantifying seabird bycatch vulnerability in global fisheries

Avian Conservation and Ecology, 2022
Fisheries bycatch, the incidental mortality of non-target species, is a global threat to seabirds and a major driver of their declines worldwide. Identifying the most vulnerable species is core to developing sustainable fisheries management strategies ...

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2837-2854, September 2026.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.
