Diet variation and trophic impact of weakfish, Cynoscion regalis, within multiple marine habitats of the eastern United States

open access: yesJournal of Fish Biology, Volume 105, Issue 6, Page 1628-1642, December 2024.
Abstract Weakfish (Cynoscion regalis) is not federally managed but feeds on species of management and ecological interest. We examined the trophic ecology of weakfish in Chesapeake Bay and the coastal and offshore waters of the eastern United States. For these areas, we determined the dominant prey of weakfish; identified how much diet variation was ...

Eyeing DNA barcoding for species identification of fish larvae

open access: yesJournal of Fish Biology, Volume 105, Issue 6, Page 1784-1799, December 2024.
Abstract Identification of fish larvae based on morphology is typically limited to higher taxonomic ranks (e.g., family or order), as larvae possess few morphological diagnostic characters for precise discrimination to species. When many samples are presented at any one time, the use of morphology to identify such specimens can be laborious and time ...

5S rDNA characterization in twelve Sciaenidae fish species (Teleostei, Perciformes): depicting gene diversity and molecular markers

open access: yesGenetics and Molecular Biology, 2008
In order to extend the genetic data on the Sciaenidae fish family, the present study had the purpose to characterize PCR-generated 5S rDNA repeats of twelve species of this group through PAGE (Polyacrylamide Gel Electrophoresis) analysis.

A comparative study of the growth of the postlarval and juvenile pescadas Plagioscion squamosissimus (HECKEL) and Plagioscion monti (SOARES) in a white water lake of the Central Amazon

open access: yes, 1983
The age of 320 specimen of Plagioscion monti and 280 specimen or P. squamosissimus was determined by means of daily rings on the otoliths. The length of the fish were in the range of 0.4 - 15 cm.

The complete mitochondrial genome of Menticirrhus littoralis (Sciaenidae, Perciformes) and its phylogeny

open access: yesMitochondrial DNA. Part B. Resources, 2020
We describe the mitochondrial genome of the Menticirrhus littoralis and infer the phylogenetic position of Menticirrhus in the family Sciaenidae. The genome contains 16,499 base pairs distributed in gene regions (13 protein-coding regions, 2 rRNAs and 22

A fish otolith assemblage from the Late Miocene (Pannonian) deposits of Lake Pannon (Doba, NW Hungary) [PDF]

open access: yes, 2012
A fish otolith assemblage consisting of 173 specimens was recovered from littoral sand deposits of the brackish Lake Pannon at Doba, western Hungary. Co-occurring endemic mollusks indicate the Lymnocardium ponticum Zone, thus an age of about 9 million ...

Two gonad-infecting species of Philometra (Nematoda: Philometridae) from marine fishes off the northern coast of Australia

open access: yesParasite, 2015
Two different gonad-infecting species of Philometra Costa, 1845 were collected from the ovary of marine perciform fishes, the blackspotted croaker Protonibea diacanthus (Sciaenidae) and the John’s snapper Lutjanus johnii (Lutjanidae), from off the ...

Demersal fish community on the inner shelf of Ubatuba, southeastern Brazil

open access: yesBrazilian Journal of Oceanography, 1998
Fluctuations in the distribution and abundance of demersal fishes collected by otter trawl on the continental shelf of Ubatuba were examined over a two-year sampling period, in an area up to 50 m depth. A total of 111 species were collected. Seasonal and
