Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Croatian Journal of Fisheries, 2018
Sagittae otoliths of eight juvenile species: Boops boops, Diplodus vulgaris, Diplodus puntazzo, Sarpa salpa (family Sparidae), Liza ramada, Liza aurata (family Mugilidae), Atherina boyeri, Atherina hepsetus (family Atherinidae) were analysed and compared

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 ...

Mismatches between genetic and assessment units in commercial fish species: A systematic review in the North‐East Atlantic

Journal of Fish Biology, EarlyView.
Abstract While sustainable fisheries depend upon spatial and temporal identification at below the species level (i.e., stock units), the choice and identification of appropriate units remain challenging. Advances in DNA sequencing and improved computational power have generated extensive genetic and genomic data on the spatio‐temporal dynamics and ...

Inter-population differences in otolith morphology are genetically encoded in the killifish Aphanius fasciatus (Cyprinodontiformes)

Scientia Marina, 2013
Inter-population differences in otolith shape, morphology and chemistry have been used effectively as indicators for stock assessment or for recognizing environmental adaptation in fishes.

Explaining decisions of deep neural networks used for fish age prediction.

PLoS ONE, 2020
Age-reading of fish otoliths (ear stones) is important for the sustainable management of fish resources. However, the procedure is challenging and requires experienced readers to carefully examine annual growth zones.

Francisella orientalis in Aquacultured Tilapia (Oreochromis spp.): A Case Work‐Up of Diagnostics and Pathologic Findings in the North Central Region (USA)

Journal of Fish Diseases, EarlyView.
ABSTRACT Tilapia (Oreochromis spp.) is an increasingly popular aquacultured fish worldwide. While tilapia enjoy a ‘hardy‐fish’ reputation among fish farmers, they are susceptible to a variety of infectious diseases that can be difficult to recognize pondside and have similarities in their gross presentations. This report describes gross and microscopic

Morphological analyses of otoliths indicate a single population of invasive Arapaima gigas in tributaries of the Upper Madeira River (Amazon Basin)

Boletim do Instituto de Pesca
The present study aimed to evaluate the potential of the shape of the sagitta otolith to discriminate populations of Arapaima gigas outside their natural area of occurrence in different tributaries of the Madeira River. Otolith samples were collected at

Long‐term stability of transcrestal sinus augmentation

Periodontology 2000, EarlyView.
Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...
