Experiments on the 1st intermediate host of the bass tapeworm, Proteocephalus ambloplitis (Leidy) showed that periods of freezing or desiccation destroy the copepods. Unsuccessful experiments to infect Cladocera with eggs of P. ambloplitis indicated the desirability of utilizing Cladocera as food for young bass in controlling the tapeworm. Copepods from bass nests during their breeding season showed 25% higher infection with P. ambloplitis procercoids than at other times. Infection data are cited for adult bass from the Lake Champlain watershed. Ecological data are presented on the infection of the Adirondack frost-fish (Prosopium quadrilaterale), smelt (Osmerus mor-dax), northern pike (Esox lucius), yellow perch (Perca flavescens), scaled ling (Amia calva) and bill fish (Le-pisosteus osseus). Metacercariae (Neascus bulboglossa) were found in 2 new hosts, young northern pike {E. lucius) and horned dace (Semotilus atromaculatus).
