This variability led early workers to recognize numerous species. Since 1758 about fity species have been described for variations in what is commonly known as brown trout (see Ferguson 1989). In the "Brown Trout Gallery", viewers can browse through some of the existing distinct brown trout phenotypes. These photographs were kindly supplied by participants of the TroutConcert.
