There and back again: migration in freshwater fishes [PDF]

, 2013
Animal migration is an amazing phenomenon that has fascinated humans for long. Many freshwater fishes also show remarkable migrations, whereof the spectacular mass migrations of salmonids from the spawning streams are the most well known and well studied.

Evolution of diadromy in fish: insights from a tropical genus (Kuhlia species) [PDF]

, 2013
Diadromous species undergo regular migration between fresh and marine waters. This behavior is found in many species, including fish, mollusks, and crustaceans, some of which are commercially valuable species.

Anadromy Redux? Genetic Analysis to Inform Development of an Indigenous American River Steelhead Broodstock [PDF]

Journal of Fish and Wildlife Management, 2019
AbstractThe construction of dams and water diversions has severely limited access to spawning habitat for anadromous fishes. To mitigate for these impacts, hatchery programs rear and release millions of juvenile salmonids, including steelhead, the anadromous ecotype of the species Oncorhynchus mykiss.

Influence of parental life history on maturation and smoltification in brown trout (Salmo trutta L.)

Archives of Polish Fisheries, 2016
The developmental pathways of the offspring of three groups of trout, Salmo trutta L., with known life histories were compared: one group from a freshwater resident population and two groups from an anadromous population (fish that have smoltified and ...

The Interplay Between Extrinsic and Intrinsic Factors in Determining Migration Decisions in Brown Trout (Salmo trutta): An Experimental Study

Frontiers in Ecology and Evolution, 2019
Many species are capable of facultative migration, but the relative roles of extrinsic vs. intrinsic factors in generating diverse migratory tactics remain unclear.

The Arctic charr (Salvelinus alpinus) genome and transcriptome assembly. [PDF]

PLoS ONE, 2018
Arctic charr have a circumpolar distribution, persevere under extreme environmental conditions, and reach ages unknown to most other salmonids. The Salvelinus genus is primarily composed of species with genomes that are structured more like the ancestral

Genotype‐Dependent Transcriptome Divergence Associated With Variation at vgll3 in Juvenile Gilthead Seabream (Sparus aurata) [PDF]

Mol Ecol
ABSTRACT Early developmental processes significantly influence growth and maturation patterns, aquaculture traits that are critical for physiological adaptation and productivity. The vestigial‐like family member 3 gene (vgll3) plays a key role in growth and maturation across diverse taxa, including mammals and teleost fishes.

Stress-linked morphological change associated with rearing techniques of hatchery-reliant endemic landlocked Atlantic salmon (Salmo salar m. sebago). [PDF]

J Fish Biol
Abstract Domestication effects caused by hatchery rearing impact various traits in fishes. Lake Saimaa landlocked salmon (Salmo salar m. sebago) have been dependent on hatchery propagation for over 50 years. The population is therefore at risk of hatchery‐induced phenotypes, which can be suboptimal in the wild, thus impacting the long‐term viability of

The influence of gene-environment interactions on GHR and IGF-1 expression and their association with growth in brook charr, Salvelinus fontinalis (Mitchill) [PDF]

, 2007
Background Quantitative reaction norm theory proposes that genotype-by-environment interaction (GxE) results from inter-individual differences of expression in adaptive suites of genes in distinct environments.
