The Surber Sampler is the classic quantitative sampler for benthic invertebrates. Designed for shallow streams less than 18" deep, one advantage is its great portability.

The Surber tech-nique is more portable for sampling in areas not readily accessible. It is a better method in areas where water currents are slow, and where streambeds contain considerable silt, sand, or …

Surber sampler – A net used for sampling aquatic insects, composed of a 12 × 12 inch square frame with a 500-micron mesh net attached. It has another 12 × 12 inch square frame that sits on the …

The stream bottom sampler (Surber Sampler) is designed for quanti tative collections in stream bottoms, particularly riffle areas where there is appreciable current which sweeps the organisms into the net …

The objective of a Surber sample is to count and identify every individual benthic macroinvertebrate collected in a known area. Since sorting usually takes several hours to several days, it must be done …

Surber Sampler: The dominant habitat for macroinvertebrates in rocky-bottomed streams is fast flowing, rocky areas called riffles, which can be sampled with quantitative methods such as Surber nets.

This collection technique uses the Surber Sampler, a 25-point grid, and Vernier calipers for measuring substrate dimensions. It may also contain methods that other users would find helpful for their …
