Is geometric morphometrics efficient for comparing otolith shape of different fish species?

Journal of Morphology, 2006
The 2D shape of sagittae of Encrasicholina devisi, E. heteroloba, E. cf. punctifer, and Stolephorus indicus, four tropical Engraulididae of New Caledonia, was studied with 1) dimensionless shape descriptors (form factor, roundness, and aspect ratio); 2) elliptic Fourier analysis (EFA) and Fast Fourier Transform (FFT) of 2D outline; and 3) geometric ...

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Maximum age of bighead carp Hypophthalmichthys nobilis exceeds 30 years: Implications for anticipating invasive species establishment and impacts

Journal of Fish Biology, EarlyView.
Abstract Invasive bighead carp Hypophthalmichthys nobilis have spread throughout the Mississippi River basin, negatively impacting ecosystems. We used a remnant population (32 years after stocking) to better understand H. nobilis. We observed high annual survival (>95%), but growth was relatively slow.

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures

Journal of Fish Biology, EarlyView.
Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...

Growth strategies across life‐history stages and generational turnover of cryptobenthic coral reef fishes of the genus Trimma

Journal of Fish Biology, EarlyView.
Abstract Somatic growth influences survival and reproduction, with flow‐on effects on population dynamics and energy fluxes within ecosystems. Small‐bodied cryptobenthic reef fishes may contribute significantly to productivity due to their life‐history traits, including growth rates and rapid generational turnover.

Mesopelagic fishes dominate otolith record of past two millennia in the Santa Barbara Basin. [PDF]

, 2019
The mesopelagic (200-1000 m) separates the productive upper ocean from the deep ocean, yet little is known of its long-term dynamics despite recent research that suggests fishes of this zone likely dominate global fish biomass and contribute to the ...

Food intake of early juvenile western Baltic cod (Gadus morhua) during settlement transition

Journal of Fish Biology, EarlyView.
Abstract This study examines the gut contents of 203 early juvenile Atlantic cod [17–101 mm ± 18.48 mm standard deviation (SD)] from the Western Baltic Sea (ICES Subdivision 22) collected between 2020 and 2022. According to the observed prey (proportion of pelagic, intermediate and benthic items) in the cod guts, settlement transition from a pelagic to

Population Structure of the Tub Gurnard (Chelidonichthys lucerna Linnaeus, 1758) in Türkiye Coasts Using Otolith Chemistry and Shape Analysis

Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries
Chelidonichthys lucerna is an economically important demersal species. It is under excessive fishing pressure and yields from fisheries are in decline in Türkiye. Information about the species' population structure and habitat connections is limited.
