Auditory chain reaction: Effects of sound pressure and particle motion on auditory structures in fishes.

PLoS ONE, 2020
Despite the diversity in fish auditory structures, it remains elusive how otolith morphology and swim bladder-inner ear (= otophysic) connections affect otolith motion and inner ear stimulation. A recent study visualized sound-induced otolith motion; but

Water temperature and river discharge drive age‐dependent changes in brown trout (Salmo trutta) growth

Journal of Fish Biology, EarlyView.
Abstract Rivers and streams exhibit inherent variability in environmental conditions, particularly in water temperature and stream discharge. These factors can impact fish growth through both direct (i.e., physiological) and indirect (i.e., ecosystem productivity) mechanisms.

Morphometric-meristic characteristics and biometry of Otoliths of tigertooth croaker (Otolithes rubber) from the Persian Gulf and Oman Sea [PDF]

بوم‌شناسی آبزیان, 2019
The Persian Gulf and Oman sea fish have valuable economic species. The purpose of this study was to evaluate morphometric properties and otolith biometry of Tigertooth croaker Otholites rober in Persian Gulf and Oman sea.

Climate change impacts on fish in the Baltic Sea

Journal of Fish Biology, EarlyView.
Abstract The Baltic Sea is a marginal sea with strong abiotic gradients harbouring fish of both marine and freshwater origin. Here we review the empirical evidence for how changes in climate variables have impacted different fish and fish communities in the Baltic Sea.

Contrasting population genetic structures of freshwater eels (Anguilla marmorata, A. bicolor, A. mossambica) from Madagascar

Journal of Fish Biology, EarlyView.
Abstract Freshwater eels (genus Anguilla) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integrity, diversity and population structure of three species of tropical eels ...

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.

Otolith Chemistry Reveals Natal Region of Larval Capelin in Coastal Newfoundland, Canada

Frontiers in Marine Science, 2020
Identifying natal origins of animals is key to determining the relative productivity of natal habitats, dispersal of individuals among local populations (i.e., connectivity), and, ultimately, metapopulation dynamics.

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

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 ...
