Abstract
This study is an effort to assess the substrate
preference of freshwater clams of the Family Unionidae.
By mechanically analyzing and comparing the various
substrates in which these clams are found and by observing
the migratory behavior of these clams when placed in
different substrates, this study has demonstrated a
definite preference of substrates by Unionids. In this
study, the migratory pattern of two species of freshwater.
clams of the Family Unionidae, Pleurobema coccineum (Conrad)
and Anodonta marginata (Say), were observed in five
different substrattes. These five substrates, gravel, fine gravel, sand, mud, and sludge, were mechanically
analyzed for water content and volume of dried earth in
order that each substrate could be compared to the natural
substrate of each species. From the observations made on
each of the above species, a hypothesis relating migration
and soil texture with substrate preference is proposed
which would generally apply to clams of the Family Unionidae.
