Data on archaeomalacological samples from Nikolaevskoe I (Primorye), a medieval settlement of Bohai (Parhae) Empire period (VIII–X centuries) located in the Chuka and Ilistaya rivers valley, Khanka Lake water basin, and their interpretations, are presented. In total, 8 species of molluscs were found, including three freshwater (2 bivalves and 1 gastropod species) and five marine (4 bivalves and 1 gastropod) species. The majority of shell fragments collected in archaeological deposits belongs to the freshwater pearl mussels Dahurinaia dahurica (Middendorff, 1850). Among marine mollusks, bivalves Anadarainaequivalvis” (Bruguière, 1789) and Glycymeris yessoensis (Sowerby III, 1889) are predominant. Descriptions of shell peculiarities as related to human use are given. A comparison of valve teeth of modern and excavated fresh-water bivalves shows their identity. Ways of utilizations of mollusks by Bohai people are discussed. Shells from Bohai archaeological deposits in Primorye are illustrated for the first time in details.
