Brown trout survived better than sympatric rainbow trout in lakes (44 versus 30%), but rainbow trout grew significantly larger than brown trout in four of six cases. Our experiments suggest that brown trout may be a viable alternative to rainbow trout in aquacultural operations....
We evaluated the movement of adult brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss in relation to a catch-and-release area in the White River downstream from Beaver Dam, Arkansas. Nine fish of each species were implanted with radio transmitters and monitored from July 1996 to July...
Social interactions between 0+ brown trout (Salmo trutta L.) and rainbow trout (S. gairdneri Richardson) were examined in a pair of stream observation troughs. The two species exhibited similar agonistic behaviour and interacted socially. As fry (< 35 mm), rainbow trout were dominant over ...

The meaning of RAINBOW TROUT is a large stout-bodied salmonid fish (Oncorhynchus mykiss synonym Salmo gairdneri) of western North America that is related to the Pacific salmon and is typically greenish above and white on the belly with a pink, red, or la
A total of 1,055, scale samples from tagged, recaptured brown trout, rainbow trout, and brook trout and 129 scale samples from planted, marked rainbow trout were taken from Prickley Pear Creek, Montana, between June 1949 and October 1951. In addition, scale samples were obtained from 69 rain...

Mean stream numerical density of the brown trout (Salmo trutta m. fario Linnaeus, 1758) and the rainbow trout (Onchorhynchus mykiss Walbaum, 1792) was 0.090 fish/m2 of which brown trout averaged 69% (72% in total biomass) in 15 high-elevation New Mexico streams (1,661-2,560 m above...
Increase of metallothionein-immunopositive chloride cells in the gills of brown trout and rainbow trout after exposure to sewage treatment plant effluents. Histochem J 1999; 31:339-346.Burkhardt-Holm, P., Bernet, D., Hogstrand, C., 1999. Increase of metallothionein- immunopositive chloride cells...
Comparison of the performance of brown trout, Salmo trutta L., and rainbow trout, Oncorhynchus mykiss (Walbaum), in a put-and-take fishery Stock and catch statistics for a small (5鈥 5ha) lowland put-and-take trout fishery have been used to investigate the relative catchability of brown,...
