SC‐550: A Sintered Calcite Reference Material for In Situ U‐Pb Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points New calcite reference material (SC‐550) produced by high‐temperature and high‐pressure sintering of nano‐particulate powder from a microbial limestone. Homogeneous U content (2.3 ± 0.4 μg g‐1) and U‐Pb isotope ratios (< 0.6% RSD for 207Pb/206Pb; < 3% RSD for 238U/206Pb).

Inner ear morphology in the Atlantic molly Poecilia mexicana - first detailed microanatomical study of the inner ear of a cyprinodontiform species [PDF]

, 2011
Background: Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.

Influence of constant and periodic experimental hypoxic stress on Atlantic croaker otolith chemistry

Aquatic Biology, 2014
The chemical composition of fish otoliths may provide information on the environmental exposure histories of fishes if ‘vital effects’ on element incorporation are minimal.

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

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.

3D otolith shape for the main commercial species (flatfish and roundfish) in the Eastern Channel and the North Sea

, 2023
Otolith shape analysis is commonly used in fisheries sciences to validate the relationship with fish length, to discriminate between stock units of fish, and to identify fish species from archeological data or stomach contents.

Spawning Ecology of Female Largehead Hairtail (Trichiurus japonicus): Inferences from the Reproductive Cycle and Otolith Chemistry

Fishes
The largehead hairtail (Trichiurus japonicus) is an economically important fish species distributed in East Asian waters; however, size- or stock-specific spawning traits in females remain poorly understood.

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

FLUCTUATING ASYMMETRY IN THE OTOLITH WIDTH AND LENGTH OF ADULT TELEOST (Beryx splendens LOWE, 1834) (FAMILY: BERCIDAE) COLLECTED FROM THE ARABIAN SEA COASTS OF SULTANATE OF OMAN [PDF]

Croatian Journal of Fisheries, 2010
Fluctuating asymmetry was described for the otolith width and length of adult teleost Beryx splendens. The results showed that the level of asymmetry of the otolith width was the highest among the two asymmetry values obtained for the otolith of B ...
