Distinct migratory and non-migratory ecotypes of an endemic New Zealand eleotrid (Gobiomorphus cotidianus) – implications for incipient speciation in island freshwater fish species [PDF]

, 2008
Background: Many postglacial lakes contain fish species with distinct ecomorphs. Similar evolutionary scenarios might be acting on evolutionarily young fish communities in lakes of remote islands.

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

DNA extracted from boiled archival fish bones yields high‐quality whole‐genome sequencing data

Journal of Fish Biology, EarlyView.
Abstract Archival samples provide a unique source of organismal DNA, offering the potential to extend the temporal scale of genetic studies by decades to centuries. Fish hard structures, such as otoliths and scales, serve as records for fish collected during fisheries monitoring across a large spatiotemporal scale.

An investigation to determine origin: age and otolith chemistry of a brown bullhead catfish (Ameiurus nebulosus) found at Okawa Bay, Lake Rotoiti

, 2009
Some time between 10 and 15 January 2009, a brown bullhead catfish(Ameiurus nebulosus) was found washed up on the shore of Okawa Bay, Lake Rotoiti. The elemental signature of the otolith was measured using laser ablation inductively coupled plasma mass ...

Growth process of grass puffer Takifugu niphobles by otolith analysis [PDF]

, 2015
Growth process of grass puffer Takifugu niphobles was analysed by sagittal otolith size measurements. The growth of otolith was monitored using otolith height (OH) . The OH increaaed rapidly from hatching to 60 days after hatching.

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.

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 ...

Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla

Journal of Fish Biology, EarlyView.
Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

An investigation of koi carp (Cyprinus carpio) movement in the Waikato region using laser ablation otolith microchemistry

, 2008
The koi carp Cyprinus carpio is an invasive fish that has reached high numbers and biomass in the North Island of New Zealand, particularly in the Waikato region. This species has a variety of negative effects on aquatic ecosystems, increasing turbidity,
