Integrating environmental DNA and trawl surveys to assess seasonal dynamics of fish communities in the Oujiang River Estuary

open access: yesFrontiers in Marine Science
IntroductionMonitoring of estuarine fish biodiversity is often constrained by the inherent limitations of traditional survey methods and the complex, dynamic environmental conditions of estuarine habitats.

Seasonal and Diel Acoustic Occurrence of Sei Whales in Oregon, USA

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The behavior, distribution, and life history of sei whales (Balaenoptera borealis) are largely unknown in the North Pacific. We analyzed data from three bottom‐mounted acoustic recorders deployed 25 (shelf; depth = 300 m), 45 (slope; depth = 630 m), and 65 (abyssal; depth = 2860 m) nautical miles off of Newport, Oregon, USA that recorded ...

Herring Today, Gone Tomorrow? Sweden's Conflict Over the 2024 Bothnian Herring Quota

open access: yesSociologia Ruralis, Volume 66, Issue 4, October 2026.
ABSTRACT This article performs a narrative policy analysis of a Swedish conflict that erupted over the EU's commercial fishing quota for Bothnian herring in the north Baltic Sea. After scientists raised alarms and the European Commission recommended closing the fishery in 2024, diverse actors sought to influence decision‐making. Their accounts diverged,

Climate Attribution in Fishery Stock Assessment: Case Studies From the Northeast U.S. Groundfish Stocks

open access: yesFish and Fisheries, Volume 27, Issue 5, Page 1107-1133, September 2026.
ABSTRACT Climate change poses an unprecedented risk to fisheries ecosystems and economies globally. Ocean warming has led to observed geographic shifts and changes in the productivity of fish stocks. Due to the rapid pace of change in many of the world's oceans, there is a critical need to develop and apply scientific knowledge and tools that can help ...

In Situ Determination Of Bottom Trawl Ground Gear Contact

open access: yes, 2001
No abstracts are to be cited without prior reference to the author.Exact definition of towed distance with proper ground gear contact is an essential parameter in bottom trawl swept area estimates of fish abundance. Errors in this key parameter may lead to a first order bias in abundance estimates of demersal fish.

Under pressure: deep-sea elasmobranchs experience high mortality and stress in a crustacean trawling fishery

open access: yesFrontiers in Fish Science
Crustacean bottom trawling in southern Portugal is an economic and culturally important fishing activity but may result in considerable bycatch of deep-sea elasmobranchs (DSE).

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Effects of Dissolved Oxygen and Hypoxia on Catch Rates of Nearshore Groundfishes in a Recreational Hook and Line Fishery

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 676-688, September 2026.
ABSTRACT Global climate change is intensifying ocean deoxygenation, particularly in eastern boundary current systems such as the California Current. This study investigates the impact of hypoxic events on a nearshore, multispecies recreational groundfish fishery along the Oregon coast.

Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...
