Brown trout and rainbow trout (average weight 100 g) were reared in fresh water at 12OC under the same conditions beforc transfer of brown trout to sea water, in order to compare nitrogen utilisation in the two species. Apparent protein digestibility (ADC), nitrogen (ammonia and urea) excretion, protein productive.
Identification: Brown trout caught in Lake. Michigan have an overall slivery color with “X" shaped marking on the back and upper half of their body, a squared tail, small and numerous spots on their head, the inside of their mouth white, and 12 or less rays in their anal fin. Spawning brown trout in September and. October will
Stocking of brown trout eggs Salmo trutta L. and construction of spawning beds are common measures in habitat restored streams. However, knowledge about how young-of- the-year (YOY) trout disperse from stocking points and spawning beds, and how it relates to biotic and abiotic factors, are sparse. This study was
The first brown trout ( Salmo trutta) arrived in North America in 1883 with the shipment of 80,000 eggs that arrived at Cold Spring Harbor on Long Island New York, some of these eggs were then sent to. Caledonia New York, the rest were sent to the US fish Commission. These eggs along with subsequent shipments of eggs

The authors summarize the important aspects of the brown trout's life history and ecology and focus on the impact caused by the species. The text explores potential

Abstract. Phylogeographic, nested clade, and mismatch analyses of mitochondrial DNA (mtDNA) variation were used to infer the temporal dynamics of distributional and demographic history of brown trout (Salmo trutta). Both new and previously published data were analyzed for 1794 trout from 174 populations.
