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

Biology, 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

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

BMC 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).

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

Scientific 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

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

Journal 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.

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

Frontiers 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 ...

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

Nauplius
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 ...

Respiratory frequency, antioxidant enzyme activities and histological observation in a backcross progeny between Acanthopagrus schlegelii and Pagrus major subjected to thermal stress

Aquaculture Reports
Temperature plays a crucial role in regulating fish growth, development, and feeding behavior. However, the limited progress in establishing a comprehensive thermal tolerance evaluation system for seawater fish can be attributed to insufficient research ...

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

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

BMC 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
