YCT Multi-state Assessment 



February 10,2003 



III CURRENT DISTRIBUTION 



Highlight all stream segments currently occupied by cutthroat trout. Give each population 

 mapping unit (segment) a unique number, circle the number and fill out form below. Also 

 complete genetic analysis information if samples are available. 



HUC Number: 



Population Mapping Unit (segment) Number: 



Species: Large Spot YCT/ Fine Spot YCT (Circle one) 

 Competing Species Present: Y or N 



Genetic Status (Circle one) 



Genetic Status 



|Genetically unaltered (>99.0%) - tested via electrophoresis or DNA 

 [introgressed (hybridized) - tested and found to be 75% to 99% YCT 

 [introgressed (hybridized) - tested and found to be less than 75% YCT 



|Potentially unaltered with no record of stocking and contaminating species present 



iPotentially hybridized with records of contaminating species being stocked or occurring in stream 

 [Hybridized and Pure populations exist In stream (use only if reproductive Isolation is suspected) 



Genetic Analyses
