How To Use Drift Nets

1. Position net(s) in flowing water, using stakes
2. After placing net in water, frequently remove organisms and debris to prevent clogging of the net mouth.
3. Specify the time of study (1 to 3 hours is recommended) and use the same time length at each station.
4. Sampling between dusk and 1 A.M. is best.
5. Drift intensity measures the total number and biomass of organisms drifting past a given station.
