Three species of salmonids, rainbow trout, Salmo gairdneri , brown trout, S. trutta , and marble trout, S. marmoratus , have been studied for their karyotypes. In rainbow trout 316 metaphases were studied and recorded 2 n of 60 with 44 meta‐ to submetacentric and 16 subtelo‐ to telo‐centric chromosomes, and the number of chromosome arms (NF) of 104. Observation on 243 metaphases of brown trout showed 2 n of 80 with 20 meta‐ to submetacentric, 60 telocentric chromosomes and the nf of 100. While in 164 metaphases from the marble trout 2 n was of the order of 80 out of which 22 were meta to submetacentric and 58 telocentric chromosomes with nf of 108.
