Quantitative: no
Rapid Assessment: No

Gear: backpack electroshocker
Method: Fractional or point-abundance sample (PAS) electrofishing gave higher density estimates for ruffe compared with conventional electric fishing.  This could lead to significant differences in biomass estimates.  PAS sampling is more advantageous in shallow lakes dominated by emergent and submergent vegetation
