Transgenerational effects of anadromy on juvenile growth traits in an introduced population of rainbow trout (Oncorhynchus mykiss)

Canadian Journal of Fisheries and Aquatic Sciences, 2014
We determined whether the propensity for anadromy was related to maternal phenotype in a population of partially anadromous rainbow trout (Oncorhynchus mykiss). We identified the maternal phenotype (anadromous versus resident) of wild juveniles from two successive cohorts using stable isotope analysis (δ15N) of muscle tissue and (or) strontium to ...

Diversification of Aquaculture Production in Relation to Global Change: The Case of the Domestication of Indigenous Euryhaline Catfish Species (Siluriformes) in the Mekong River Delta, Viet Nam

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT The Mekong River Delta, the heart of Vietnam's aquaculture industry, is facing many challenges due to climate change, particularly salinity intrusion. In this context, this review aimed to assess the potential of indigenous euryhaline catfish species to diversify fish farming, strengthen food security, and build resilience in the region. Among

Introduction and extinction of brown trout (Salmo trutta L.) in an impoverished subantarctic stream [PDF]

, 1992
Brown trout were introduced to the Van den Boogaard River on subantarctic Marion Island in 1964, and a small population became established. The last individual was seen in 1984, and the species is now considered to be extinct on the island.

First glimpse into parasites of Arctic anadromous lake trout

Arctic Science
Partial anadromy, where some individuals remain in freshwater while others migrate to sea, is common at northern latitudes. These life history differences can have ecological consequences impacting the parasite infracommunity, as parasite exposure varies

Effects of salmon lice Lepeophtheirus salmonis on wild sea trout Salmo trutta—a literature review

Aquaculture Environment Interactions, 2015
Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, skin and muscle, and infestation

The spawning migration of anadromous rainbow trout in the Santa Cruz River, Patagonia (Argentina) through radio-tracking

Ecología Austral, 2003
Adult anadromous rainbow trout (Oncorhynchus mykiss) from the Santa Cruz River were implanted with radio-transmitters in May 2000 as they ascended the river from the ocean to locate spawning areas, assess the range and timing of the spawning migration ...

A novel sperm adaptation to evolutionary constraints on reproduction: Pre‐ejaculatory sperm activation in the beach spawning capelin (Osmeridae)

Ecology and Evolution, 2018
Reproduction of external fertilizing vertebrates is typically constrained to either fresh or salt water, not both. For all studied amphibians and fishes, this constraint includes immotile sperm that are activated after ejaculation only by the specific ...

Does life‐history variability in salmonids affect habitat use by juveniles? A comparison among streams open and closed to anadromy [PDF]

Journal of Animal Ecology, 2006
Summary Migratory and resident forms of salmonids coexist in many river systems. Although such coexistence is widespread, little is known about its ecological basis and no studies have compared the habitat use of premigratory juveniles and residents. We employed a comparative approach to explore the differential habitat use of juvenile anadromous and ...

Genomic Insights Into Diversity, Phylogeny, Hybridization and Evolutionary History of Palearctic Fish Genus Rutilus (Leuciscidae)

Diversity and Distributions, Volume 31, Issue 12, December 2025.
ABSTRACT Aim Using a widely distributed and frequently hybridising fish (genus Rutilus) in the Palearctic as a model system, we re‐evaluated a series of hypotheses on phylogeny, taxonomy, phylogeography and the role of hybridization in evolutionary history based on the first large‐scale analyses of nuclear SNPs together with mtDNA data obtained from ...

Genomic insights on conservation priorities for North Sea houting and European lake whitefish (Coregonus spp.)

Molecular Ecology, Volume 34, Issue 23, December 2025.
Abstract Population genomics analysis holds great potential for informing conservation of endangered populations. We focused on a controversial case of European whitefish (Coregonus spp.) populations. The endangered North Sea houting is the only coregonid fish that tolerates oceanic salinities and was previously considered a species (C.
