Otolith morphology as a tool for stock discrimination of three rockfish species in the East Sea of Korea

Frontiers in Marine Science, 2023
The shape and structure of otoliths play a vital role in studying fish populations because otolith shape indices are often applied to discriminate fish species.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Relationships of Otolith Dimensions and Weight with Body Length of Three Lethrinid Species (Actinopterygii, Lethrinidae) from Yemen

Zoodiversity
Relationships between fish length and otolith length, width, and weight were studied in three lethrinid species Lethrinus borbonicus Valenciennes 1830, Lethrinus lentjan (Lacepède 1802), and Lethrinus mahsena (Fabricius, 1775) collected from the south of

Subjective Visual Vertical Can be an Effective Tool to Evaluate Vestibular Function of Stapedotomy

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To investigate if the subjective visual vertical/horizontal (SVV/SVH) can be used to evaluate the otolith organ of otosclerosis and stapedotomy. Design A total of 19 patients who were diagnosed with otosclerosis and underwent surgical treatment in our hospital were collected.

Impacts of Ocean Acidification on Reproduction and Early Life Development in Marine Teleost Fish—A Synthesis

Fish and Fisheries, EarlyView.
ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.

Comparative investigation of the relationships between otolith weight and size with fish length in Neogobius species in the Southern part of the Caspian Sea [PDF]

بوم‌شناسی آبزیان, 2019
In this study, the relationships between otolith weight and dimensions with fish length were investigated in Neogobius species from Gobiidae. During this research, 149 specimens belong to three species, Neogobius pallasi, N. caspius and N.

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Otolith structure as indicator of key life history events in Atlantic cod (Gadus morhua) [PDF]

, 2018
Otoliths are remarkable recorders of the individual life history, as they can reflect the growth trajectory and may encapsulate marks related to ontogenetic, physiological and environmental events.

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian Ocean

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key
