Description of a Typical Survey
The basic idea• Make sure you are on the correct stream and segment (many surveys, but
not all will have signs, use GPS)
• Find your start point and survey upstream to end point
• During the survey count all live and dead fish
• Count all Redds • Collect all carcasses and take them back to the council office
• Identify species, sex, and take biological samples [scales, snouts]
• Zero data point is valuable-start and end of season [run timing]-No fish seen throughout season
