Sensitivity of fish diel vertical migration depths to future changes in the Pacific Ocean oxygen minimum zone

open access: yesFrontiers in Marine Science
Diel vertical migrations in the ocean play a key role in predator-prey dynamics and the functioning of the biological carbon pump. However, changes in ocean conditions including warming and deoxygenation threaten to significantly perturb vertical ...

Diel release timing is a critical determinant of reef fish survival in Post‐larval Capture, Culture, and Release

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Predation is a dominant force shaping survival of coral reef fishes. Synchronous, nocturnal settlement during low‐light, new moon periods may have developed as an adaptive response to intense predation during settlement. Post‐larval Capture, Culture, and Release (PCCR), where juvenile fishes are released directly to the reef ...

A new Activity Monitor for Aquatic Zooplankter (AMAZE) allows the recording of swimming activity in wild-caught Antarctic krill (Euphausia superba)

open access: yesScientific Reports
Antarctic krill (Euphausia superba, hereafter krill) is a pelagic living crustacean and a key species in the Southern Ocean ecosystem. Krill builds up a huge biomass and its synchronized behavioral patterns, such as diel vertical migration (DVM ...

Integrating Acoustic Telemetry and Stable Isotope Data Reveals Overlap in Resource Use by Large‐Bodied Fishes in a Temperate Lake

open access: yesEcology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Temperate lake ecosystems undergo seasonal shifts that disproportionately alter the availability of suitable habitat for fishes of different thermal guilds. While many studies have investigated fish habitat use patterns, few have estimated the degree to which fish species overlap in space across seasons from a three‐dimensional perspective ...

Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

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 ...

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...

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 ...
