This sampler is used if the objective is to
compare sampler catches with the population of a
surrounding rocky substrate. The basket can be
loaded with materials simulating the natural bed on
which it lies. This sampler is useful for lakes,
shallow streams, or for deep, swift rivers. The
sampler consists of a collapsible basket holding
gravel or rocks and is surrounded by a nylon netting
bag of 1/2" sq. in. mesh. A 18" SST rim around the
top helps retain the gravel. When lowered to the
bottom, the basket collapses to form an area of
gravel that is subsequently colonized. When raised
off the bottom, the basket extends to its original
hemispherical shape and the surrounding net bag
prevents loss of invertebrates during retrieval.
