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.

Age, growth and sexual dimorphism of the monkeyface prickleback (Cebidichthys violaceus)

Journal of Fish Biology, EarlyView.
Abstract Accurate estimates of age, growth and maturation are fundamental to fisheries assessment, conservation and the development of emerging aquaculture species. However, life‐history parameters can vary within species and may be influenced by factors such as sexual dimorphism, which is often poorly quantified in non‐commercial or understudied ...

Otolith Shape Analysis and Otolith Morphometry of Bogue Boops boops (Linnaeus, 1758) in the Aegean Sea and the Marmara Sea

Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries
In the present study, otolith shape indices and some otolith morphometric characteristics in the left and right sagittal otoliths were identified and compared for Boops boops in the Aegean Sea and the Marmara Sea.

Precision and Bias of Cleithra and Sagittal Otoliths Used to Estimate Ages of Northern Pike

Journal of Fish and Wildlife Management, 2013
Abstract Cleithra are thought to accurately record age information and produce the most reliable age estimates relative to other calcified structures (e.g., scales) for long-lived species of Esocidae such as muskellunge Esox masquinongy and northern pike E. lucius.

Sex‐dependent divergence in river use following maturation in Japanese seabass Lateolabrax japonicus revealed by otolith Sr:Ca chronologies

Journal of Fish Biology, EarlyView.
Abstract Partial migration, in which migratory and resident individuals coexist within a population, is widespread in fishes and contributes to population resilience. However, the role of sex in shaping migratory strategies remains poorly understood. Herein, we examined partial migration in Japanese seabass Lateolabrax japonicus using sex ratios and ...

Pitfalls in diagnosing and long‐term management of ceroid lipofuscinosis NCL4A in a mixed‐breed dog

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract An 8‐year‐old, spayed, female, mixed‐breed dog was presented with a 9‐month history of occasionally stumbling on walks, having difficulty navigating stairs and jumping into the car. A prior computed tomography scan of the head revealed mild leptomeningeal enhancement and suggested meningoencephalitis.

Multiscale analysis on otolith structural features reveals differences in ontogenesis and sex in Merluccius merluccius in the western Adriatic Sea

Royal Society Open Science, 2022
Otolith biomineralization results from biochemical processes regulated by the interaction of internal (physiological) and external (environmental) factors which lead to morphological and ultrastructural variability at intra- and interspecific levels. The

Relationships Between Oceanic Primary Production, Human Habitation and Variation in the Life‐History Traits of Coral Reef Fishes Across the Northern Line Islands

Fish and Fisheries, Volume 27, Issue 6, Page 1269-1282, November 2026.
ABSTRACT Biophysical processes associated with large‐scale nearshore oceanographic upwelling can influence coral reef communities by increasing the delivery of nutrient subsidies and food resources to reefs. However, these processes occur alongside anthropogenic activities that may alter ecological patterns across coral reef ecosystems.

Dynamics of Growth–Feeding Mechanisms in Japanese Anchovy Larvae Under Different Environmental Conditions

Fisheries Oceanography, Volume 35, Issue 6, Page 923-945, November 2026.
ABSTRACT The linkage between growth rate and feeding success in fish larvae has received much attention as a potential indicator of future growth and survival potential. Given the increasing evidence that the growth–survival relationship is highly variable, the growth–feeding linkage would also exhibit variable dynamics among cohorts of the same ...

Variations in Otolith and Scale Shape of the Invasive Round Goby Neogobius melanostomus Populations from Different Habitats of the Sava River Basin, Croatia

Croatian Journal of Fisheries, 2023
Round goby Neogobius melanostomus is one of the three invasive Ponto-Caspian gobies found in the Sava River basin in Croatia. It has a negative effect on the native ecosystems due to its high invasive potential that enables its rapid spread upstream in ...
