Native Rainbow Trout In Montana [PDF]

, 1978
Previous reports have indicated the absence of rainbow trout as native in Montana. All planted rainbow trout in Montana came indirectly from the McCloud River in California and were originally derived from a coastal steelhead trout population ...

A common garden experiment in the wild reveals heritable differences in migration tendencies among brown trout populations

Journal of Fish Biology, EarlyView.
Abstract We undertook a common garden experiment in the Burrishoole catchment, western Ireland, to test for heritable life‐history differences among neighboring brown trout (Salmo trutta L.) populations that exhibit neutral genetic divergence. Experimental crosses were made using either local females (obtained from a below‐waterfalls section of the ...

Comparative metabolomics analysis based on LC-MS method reveals regulatory difference in lipid metabolism and fatty acids metabolism between diploid and triploid rainbow trout (Oncorhynchus mykiss)

Aquaculture Reports
Diploid rainbow trout gonadal development occurs at the expense of stored energy and nutrients, lipid mobilization supplies energy required for this process.

Organic Aquaculture – the link between sustainable production and superior products [PDF]

, 2008
The first Danish organic rainbow trout with the Danish red Ø label was introduced to the market in 2005. The demand for organic trout is increasing and Danish trout farmers are currently con¬verting to organic production.

Acclimation conditions and subsequent acute hypoxia challenges do not affect the frequency of erythrocyte nuclear segmentation in triploid brook charr Salvelinus fontinalis (Mitchill 1814)

Journal of Fish Biology, EarlyView.
Abstract Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whether it affects erythrocyte function.

Effect of heterozygosity, ploidy and incubation temperature on post‐cranial axial skeletal meristics and deformities in Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract The teleostean post‐cranial axial skeleton is a highly specialized structure for an aquatic mode of life. However, there is limited knowledge regarding parental contributions, early‐life environmental impacts on its meristic variation and if reduced heterozygosity challenges its development.

Brook Trout Enhancement Through Rainbow Trout Removal by Electroshocking in the Great Smoky Mountains National Park [PDF]

, 1986
Brook trout ( Salvelinus fontinalis) populations have declined in the Great Smoky Mountains National Park since the early 1900\u27s. The continuing range loss of the Parks\u27 only native trout species has been attributed mainly to the introduced rainbow

Testing non‐lethal techniques for endoparasite detection and sex determination in pumpkinseed sunfish (Lepomis gibbosus)

Journal of Fish Biology, EarlyView.
Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound
