Suction sampling is a small-scale, objective procedure to
collect baseline information, particularly on biodiversity,
in a given area. A vacuum-type device will be used to
suction samples in an area to obtain ‘whole community’ and
potential key species information. This type of sampling
involves lifting small organisms from exposed hard bottoms
through suction generated by compressed air into a 2-4
inch diameter pipe. The gentle current created lifts
small, mobile organisms into the pipe, capturing them
in a mesh bag tied to the end of the pipe. Suction sampling
has been used extensively in benthic ecology and fisheries
(e.g., Brett, 1964; Hiscock & Hoare, 1973; Keegan & Konnecker,
1973). Recently the method has been employed very successfully
in large-scale biodiversity inventory efforts (Bouchet
et al. 2002). Suction sampling is the most effective
method for surveying small or cryptic mobile invertebrates
from exposed hard bottoms.
