Pelagic Larval Duration and Population Structure of a Widely Distributed Amphidromous Fish in the Indo‐Pacific Region

open access: yesEcology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Freshwater habitats in the Indo‐Pacific Islands are colonised by amphidromous fish, which undergo a marine larval phase while the rest of the life cycle takes place in the riverine habitat. These fish are mainly represented by Gobiiformes. Among these, Stenogobius genivittatus (Valenciennes, 1837) is widely distributed in the Indo‐Pacific ...

Shifting Harbor Seal (Phoca vitulina) Diet May Reflect Ecosystem Changes in Skagerrak

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Harbor seals, as generalist predators, can adjust their diet in response to shifts in prey availability; thus, their diet composition has the potential to act as a biodiversity indicator. This study examined the diet of harbor seals in the Skagerrak by analyzing otoliths from scat samples collected in 2020 and compared species composition to ...

Norwegian Sea Herring Stock Discrimination phase I (NORDISI) [PDF]

open access: yes
There is growing concern among fishermen about the migration of North Sea herring into the Norwegian Sea. The Pelagic Freezer-trawler Association therefore commissioned IMARES to develop a technique to monitor possible catches of North Sea herring in the

Transitions in the morphological features, habitat use, and diet of young-of-the-year goosefish (Lophius americanus) [PDF]

open access: yes, 2007
This study was designed to improve our understanding of transitions in the early life history and the distribution, habitat use, and diets for young-of-the-year (YOY) goosefish (Lophius americanus) and, as a result, their role in northeastern U.S ...

Diversification of Aquaculture Production in Relation to Global Change: The Case of the Domestication of Indigenous Euryhaline Catfish Species (Siluriformes) in the Mekong River Delta, Viet Nam

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT The Mekong River Delta, the heart of Vietnam's aquaculture industry, is facing many challenges due to climate change, particularly salinity intrusion. In this context, this review aimed to assess the potential of indigenous euryhaline catfish species to diversify fish farming, strengthen food security, and build resilience in the region. Among

Effects of aging on otolith morphology and functions in mice

open access: yesFrontiers in Neuroscience
BackgroundIncreased fall risk caused by vestibular system impairment is a significant problem associated with aging. A vestibule is composed of linear acceleration-sensing otoliths and rotation-sensing semicircular canals.

Investigation of otolith responses using ground based vestibular research facility [PDF]

open access: yes
The general goal was to examine tilt sensitivity of horizontal semicircular canal afferents. Computer programs were tested which controlled the short axis centrifuge at the Vestibular Research Facility, acquired action potentials and produced data ...

Age and growth of swordfish (Xiphias gladius) caught by the Hawaii-based pelagic longline fishery [PDF]

open access: yes, 2007
We verified the age and growth of swordfish (Xiphias gla-dius) by comparing ages determined from annuli in fin ray sections with daily growth increments in otoliths.

Otolith Age Analysis Reveals Lifespans Greater Than 50 Years for the Three Species of Carpsucker (Carpiodes spp.) in Wisconsin

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT The carpsuckers (Carpiodes spp.) are a little‐studied genus of three medium‐sized (0.5–3 kg at maturity) freshwater fishes within Catostomidae. These three species are widespread and common in some larger rivers in central North America, as well as some larger lakes and reservoirs.
