Abstract

The eastern elliptio (Elliptio complanata) is a common, abundant and ecologically important freshwater mussel that occurs throughout the Atlantic Slope drainage in the United States and Canada. Previous research has shown E. complanata glochidia to be host fish generalists, parasitizing yellow perch (Perca flavescens), banded killifish (Fundulus diaphanus), banded sculpin (Cottus carolinae), and seven centrarchid species. Past laboratory studies have been conducted in the Midwest and glochidia sources typically included lakes the Great Lakes basin or were unreported. The objective of this study was to identify host fishes for E. complanata from streams in the Mid-Atlantic region. We used artificial laboratory infections to test host suitability of 38 fish and two amphibian species with E. complanata glochidia from the Chesapeake Bay drainage. Glochidia successfully metamorphosed into juvenile mussels on five fish species: American eel (Anguilla rostrata), brook trout (Salvelinus fontinalis), lake trout (S. namaycush), mottled sculpin (C. bairdii), and slimy sculpin (C. cognatus). American eel was the most effective host, yielding the highest overall metamorphosis success (percentage of attached glochidia that transformed into juvenile mussels;{greater than or equal to}0.90) and producing 13.2 juveniles per fish overall. No juvenile E. complanata metamorphosed on other fish species tested, including many previously identified host fishes reported in the literature. Reasons for discrepancies in published host fish could include geographic variation in host use across the species' range, differences in host use between lentic and lotic populations, or poorly resolved taxonomy within the genus Elliptio.
