Management Plan for the Yellow Lampmussel (Lampsilis cariosa) in Canada

The yellow lampmussel (Lampsilis cariosa) is a freshwater bivalve mollusc that is typically up to 75 mm in length and is almost oval in outline, with a glossy, bright yellow or reddish brown outer shell. It is a suspension feeder which filters organic debris and phytoplankton from the water. The sexes are separate and early larval (glochidial) development takes place within females. Development proceeds through a period of parasitism where the larvae attach to the gills of a host fish species, usually white perch (Morone americana) or yellow perch (Perca flavescens), although there may be other suitable species. Young mussels drop to bottom sediments to grow to adult size. Usually found on level, sand and gravel bottoms in medium- large rivers, they can also be found in lakes and reservoirs on sandy bottoms with sparse vegetation.
