A simple and efficient drift sampler

Abstract: A drift sampler for use in small streams is described. The mouthpiece is the rectangular end of a plastic adaptor for rainwater guttering, and a 1 m long, 45 µm mesh net is attached to the circular posterior. Three such adaptors, plus nets, are placed side by side 70 mm apart and attached to aluminium flat. The whole structure is attached to metal stakes driven into the stream bed. The catch of the sampler is compared with a standard drift sampler, and the replicates are analysed for variance.

“…The smaller opening faced upstream to reduce clogging and to increase the efficiency of the net (Elliott, 1970;MuirheadThomson, 1987). This was confirmed by observing the flowofdye through thesamplers (Field-Dodgson, 1985). This design also allowed for the upstream opening of the sampler to be raised from the bottom of the stream so that invertebrates could enter the sampler only by drifting.…”

“…Drift sampling was conducted monthly beginning 1 month after the flood and ending 12 months later (no preflood drift data were available). Three drift samplers, similar to those described by Field‐Dodgson (1985), were set approximately 30 m apart in mid‐water at each site. Each sampler consisted of a Marley guttering sump (sampling area 0.0066 m 2 ) to which was attached a 1 m long net with 0.5 mm mesh to reduce clogging.…”

“…Drift samples were collected with 300 |im mesh nets fitted to plastic samplers (mouth area of each sampler = 58.0 cm 2 ) as described by Field-Dodgson (1985). Three replicate samplers were placed in each river section immediately below a riffle of uniform depth, and set so that the top of the sampler mouth was just above the water surface.…”
