Ecology of Corbicula Manilensis Philippi in the Ohio River at Louisville, Kentucky

---

Abstract

A population of the Asiatic Clam, Corbicula manilensis Philippi, in the Ohio River at Louisville, Kentucky was studied from July, 1963 through July, 1964. Spawning activity in late summer and fall increased the population to its yearly maximum in winter, but the population density was greatly diminished by high mortality in March, 1964. The die-off affected all age classes and seemed to be brought about by increased suspended sediment loads that accompanied spring floods. Spawning began to increase the number of clams in late summer. Qualitative observations in 1965 and 1966 showed the spring mortalities to be annual occurrences in the Ohio River.
