Description of a Typical Survey

Page 10: Spawning Survey Methods

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
