Protocol Details for Monitoring Aquatic Nuisance Species Protocol Details for Monitoring Aquatic Nuisance Species



Fish - Ruffe
Multiple - benthic
Qualitative: no
Quantitative: Yes
Rapid Assessment: No
Specs:
Distance:
Frequency:
Gear: electroshock boat
Method:

Although the 4.9 m trawl is the primary gear used in this sampling programme, alternative gears such as this one are sometimes used when the large trawl is unfeasible.

Boat boom electrofishing with 360 to 580 V pulsed DC at 8 amps is an laternative gear used in shallow water of un-even bottoms where trawling is unfeasible.  Effort is recorded in minutes electrofished and would consist of 30 minutes effort per sampling location
