Data is included for three sets of laboratory experiments where various fish species were tested in several multi-week trials to determine their suitability in serving as parasitic hosts for larvae of the freshwater mussel named dwarf wedgemussel (Alasmidonta heterodon) from the Mid-Atlantic region and New England of the United States. The first set of experiments tested host suitability of multiple fish species, the second compared host suitability of groups of tessellated darters (Etheostoma olmstedi; a known host) from multiple locations, and the third tested host suitability of individual tessellated darters. Results are reported in numbers of juvenile mussels per fish (JPF; total juvenile mussels produced by...

Data is included for two types of field surveys conducted for freshwater mussels in the mainstem of the middle and upper Delaware River in the Mid-Atlantic region of the United States from 2000-2002. Timed search (qualitative) surveys were conducted during 2000-2001 from a point at the confluence of the East and West Branches of the Delaware River near Hancock, NY continuously downstream to a point at the mouth of the Paulins Kill River near Columbia, NJ. In this qualitative survey, mussel species and counts were collected in the field catch-per-unit-effort (CPUE) data was determined for all mussel species within each of 1,095 consecutive stream sections ~200 m in length. Subsequent quantitative surveys were conducted...
