Population-level shape variation and otolith asymmetry in Diplodus annularis. [PDF]
Sci RepSound detection in fishes relies on the inner ear and peripheral structures, such as calcareous otoliths, which play a crucial role in perceiving movement, orientation, and balance. Otoliths, in particular, respond to various environmental factors including temperature, salinity, and food availability, making them valuable indicators of ecological ...

Clarifying species identity in Aphanopus using wavelet-based otolith shape analysis. [PDF]
PLoS OneAccurate species identification is crucial for effective fisheries management, particularly for cryptic species with overlapping ranges and similar morphologies. This study explores the coexistence and distribution of Aphanopus carbo and Aphanopus intermedius in the northeastern Atlantic over four decades using otolith contour analysis. Otolith samples

Frontiers in Marine Science, 2015 Analysis of elemental and isotopic compositions and of the shape of fish otoliths has become an important tool in fish ecology. Highly relevant questions like origin and migration of fish over their life time cannot be answered easily with other methods.

Dentex maroccanus Valenciennes, 1830 Otolith Morphology, Age, and Growth in the Aegean Sea (E. Mediterranean) [PDF]
AnimalsOtoliths are important structures for balance and hearing of fish and constitute a useful tool in fisheries science. This study provides, for the first time in the Mediterranean, information on the otolith morphometrics of Dentex maroccanus, collected ...

Using otoliths for fish stock discrimination: status and challenges [PDF]
Acta Ichthyologica et Piscatoria, 2021 Otoliths are calcified structures and the information contained within their chemistry or shape can be used to infer life history events, migration patterns, and stock structure of a fish population.

Paradox of otolith shape indices: routine but overestimated use [PDF]
Canadian Journal of Fisheries and Aquatic Sciences, 2021 The identification of fish species using otolith shape has been common in many fields of the marine science. Different analytical processes can be applied for the morphological discrimination, but reviewing the literature we have found conceptual and statistical limitations in the use of shape indices and wavelets (contour analysis), being specially ...

Fishes, 2022 Otoliths, calcified structures in the inner ears, are used to estimate fish age, and their shape is an efficient fish stock identification tool. Otoliths are thus very important for the management and assessment of commercial stocks.

The effect of growth rate on otolith-based discrimination of cod (Gadus morhua) ecotypes.
PLoS ONE, 2021 Otolith shape has previously been used to identify ecotypes within the Icelandic cod (Gadus morhua) stock, using DST profiles to validate the results. Fish otolith shape variation has repeatedly been found to be largely determined by growth rate.
