Size Selective Harvesting Does Not Result in Reproductive Isolation among Experimental Lines of Zebrafish, Danio rerio: Implications for Managing Harvest-Induced Evolution

open access: yesBiology, 2021
Size-selective mortality is common in fish stocks. Positive size-selection happens in fisheries where larger size classes are preferentially targeted while gape-limited natural predation may cause negative size-selection for smaller size classes. As body

Evidence of unidirectional gene flow in a fragmented population of Salmo trutta L.

open access: yesScientific Reports, 2021
Selection, genetic drift, and gene flow affect genetic variation within populations and genetic differences among populations. Both drift and selection tend to decrease variation within populations and increase differences among populations, whereas gene

Evolutionary patterns of diadromy in fishes: more than a transitional state between marine and freshwater

open access: yesBMC Evolutionary Biology, 2019
Background Across the tree of life there are numerous evolutionary transitions between different habitats (i.e., aquatic and terrestrial or marine and freshwater).

New host records of parasitic isopods of Tropical Eastern Pacific marine fishes, with remarks on the taxonomy and distribution of the species [PDF]

open access: yesNauplius
Marine fishes harbor a wide array of metazoan parasites, including helminths and crustaceans such as copepods and isopods. Even though the coast of Sinaloa stands out in Mexico by the volume of captured marine fishes, information about the diversity of ...

Skin Mucus of Marine Fish as a Source for the Development of Antimicrobial Agents

open access: yesFrontiers in Marine Science, 2020
Fish skin mucus is an important component of the innate immune mechanism and provides a first barrier against pathogens. Although several studies investigated and demonstrated the antimicrobial properties of skin mucus of fishes, most of them tested ...

Taphonomy of Early Triassic fish fossils of the Vega-Phroso Siltstone Member of the Sulphur Mountain Formation near Wapiti Lake, British Columbia, Canada

open access: yesJournal of Palaeogeography, 2013
The taphonomy of fishes living in lacustrine environments has been extensively studied in both the laboratory and the fossil record; the taphonomy of marine fishes, however, is poorly known.

Fabrication of environmentally safe antifouling coatings using nano-MnO2/cellulose nanofiber composite with BED/GMA irradiated by electron beam

open access: yesScientific Reports, 2023
Marine biofouling, undesirable growth of organisms on submerged surfaces, poses significant challenges in various industries and marine applications. The development of environmentally safe antifouling coatings employing nano-MnO2/cellulose nanofiber ...

Triassic actinopterygians across Tethys: state of the art [PDF]

open access: yesResearch & Knowledge, 2017
During the 5th International Meeting on Mesozoic Fishes held at Santillo, Mexico, we first presented the great novelty of the marine Triassic findings in southern China.

Hindering the biofilm of microbial pathogens and cancer cell lines development using silver nanoparticles synthesized by epidermal mucus proteins from Clarias gariepinus

open access: yesBMC Biotechnology
Scientists know very little about the mechanisms underlying fish skin mucus, despite the fact that it is a component of the immune system. Fish skin mucus is an important component of defence against invasive infections. Recently, Fish skin and its mucus

Molecular Identification and Functional Characterization of LC-PUFA Biosynthesis Elongase (elovl2) Gene in Chinese Sturgeon (Acipenser sinensis)

open access: yesAnimals
Elongases of very-long-chain fatty acids (Elovls) are critical rate-limiting enzymes that are involved in LC-PUFA biosynthesis through catalyzing the two-carbon elongation of a pre-existing fatty acyl chain. Thus far, several Elovls have been extensively
