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

open access: yesJournal 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 ...

Phylogeny of Gadidae based on fossil and recent otoliths with special emphasis on the evolution of Micromesistius and Gadiculus

open access: yesFrontiers in Marine Science, 2015
Otoliths are a powerful tool in reconstructing the family tree of the Gadidae in its strict sense, thus only including the cods with three dorsal fins.

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

open access: yesJournal 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.

Transitions in the morphological features, habitat use, and diet of young-of-the-year goosefish (Lophius americanus) [PDF]

open access: yes, 2007
This study was designed to improve our understanding of transitions in the early life history and the distribution, habitat use, and diets for young-of-the-year (YOY) goosefish (Lophius americanus) and, as a result, their role in northeastern U.S ...

Ensembles of wrappers for automated feature selection in fish age classification [PDF]

open access: yes, 2017
In feature selection, the most important features must be chosen so as to decrease the number thereof while retaining their discriminatory information. Within this context, a novel feature selection method based on an ensemble of wrappers is proposed and

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

open access: yesJournal 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

Murray-Darling basin freshwater shells: riverine reservoir effect [PDF]

open access: yes, 2009
We report carbon isotope measurements on pre-bomb museum samples of freshwater mussel shells collected alive from riverine locations in New South Wales, Australia. The calculated reservoir ages, ranging from -60 to +112 years, are much smaller than those

Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...

An allometric smoothing function to describe the relation between otolith and somatic growth over the lifespan of walleye pollock (Theragra chalcogramma) [PDF]

open access: yes, 2007
We propose a new equation to describe the relation between otolith length (OL) and somatic length (fork length [FL]) of fish for the entire lifespan of the fish.

Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: a synthesis and review [PDF]

open access: yes, 1996
The stable oxygen isotope composition (d¹⁸O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (d¹³C) reflects the source of CO2 for ...
