New cards

Dip/Sweep Net or D-frame Net

  • quantitative method

  • pelagic and submerged plant inverts (backswimmers, nymphs, water boatmen)

  • standardized sweep at multiple spots (certain depth or rotate certain distance)

  • accuracy depends on mesh size and skill, mesh size determines inverts retained

New cards

Stovepipe

  • quantitative method

  • benthic (bottom dwelling) or water column inverts

  • diameter of stovepipe used to quantify area sampled

  • standardized # of hand nets drawn from stovepipe across sites as a “sample of a sample”

Benthic Corer

  • quantitative method 

  • benthic (bottom dwelling) inverts (mostly worms)

  • diameter of core used to quantify area sampled

Eckman Dredge/ Eckman Grab 

  • quantitative method 

  • benthic inverts in water that’s too deep to be accessible

  • surface area of base used to estimate area sampled

  • best in soft sediments and not good in vegetation or stony sediments

Aerial sweepnet

  • quantitative method 

  • aerial inverts (dragonflies, mayflies, stoneflies)

  • mesh size determines inverts retained

Wash bucket

  • used to wash out excess sediment and detritus primarily from benthic core and stovepipe samples

  • not a technique necessarily, but the mesh size determines what subset of inverts are “kept”
