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

open access: yesZoodiversity
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

Estimating European Pilchard (Sardina pilchardus) Total Length: New Equations for the Ichthyoarchaeological Record

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Throughout its area of distribution, in particular in the Iberian Peninsula, the European pilchard (Sardina pilchardus Walbaum 1792) has been an extensively exploited species since Prehistoric times. Our knowledge of the past fisheries of this clupeid nevertheless remains limited due to a scarcity of ichthyoarchaeological data, which reflects,

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

open access: yesOikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

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]

open access: yesبوم‌شناسی 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.

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

open access: yesRemote 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 ...

Otolith morphometry and its role in determining the growth of Periophthalmus chrysospilos distributed in some coastal provinces in the Mekong Delta

open access: yesVeterinary Integrative Sciences
This article first provided information on otolith shapes, the variation of otolith weight by sex, fish size, season, and sampling site, and the linear relationship between otolith weight and fish size. A total of 815 Periophthalmus chrysospilos

Otoliths as individual indicators: a reappraisal of the link between fish physiology and otolith characteristics

open access: yes, 2016
Otoliths are remarkable recorders that store visual and chemical information that can be interpreted with regard to individual fish phenotype trajectory, life history events and environment.

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

open access: yesWorld 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.

Investigation of otolith asymmetry in Mulloidichthys flavolineatus and Parupeneus forsskali (Perciformes: Mullidae) from Egypt’s Hurghada fishing harbour on the Red Sea

open access: yesOceanological and Hydrobiological Studies, 2023
The current study aims to calculate and assess the asymmetry of the two goatfish species, Yellowstripe goatfish Mulloidichthys flavolineatus (Lacepède 1801) and Red Sea goatfish, Parupeneus forsskali (Fourmanoir & Guézé 1976) collected from Hurghada ...

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

open access: yesArchaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...
