BIVALVE AGE AND GROWTH Neiman (1964) examined the age composition of bivalve moUusks in the middle zone of the eastern Bering Sea shelf and found that a large percentage of the population consisted of clams between four and six years old. She hypothesized that the benthos of the middle shelf was not heavily utilized as food by higher trophic levels and that such predators as flatfishes were excluded from the area by the pres- ence of low water temperatures during the winter. In May 1976, we collected bivalves in the area from which the 1961 collections were made in an effort to extend the information on abundance, age composi- tion, and growth history. The size and age data and growth histories of Nucula tenuis, Nuculana fossa, Yoldia amygdalea, and Macoma calcarea were deter- mined . Growth information is also presented for two larger species of clams, Spisula polynyma and Tellina lutea.
