Size and age structures of the bivalve mollusk Ruditapes philippinarum population in the shallow waters of South Primor'e

Oceanology, 40(5):693-699.

The peculiarities of the size and age structures of Ruditapes philippinarum were studied in 13 various habitats located in five bays and bights of South Primor'e. Substrate stability has the greatest effect on the character of the age and size structures of the Ruditapes philippinarum populations. The life span and the most balanced population structures are typical of the mollusks inhabiting solid sediments (gravel-pebble, gravel, and boulder). Populations living over soft sediments from the areas with high hydrodynamic activity are characterized by the predominance of juveniles and lack of mollusks of older age (size) classes. At the shallow-water sites well protected from the wave action, the character of the age (size) distribution is mostly influenced by the ice regime. The maximum lifetime of Ruditapes philippinarum in the South Primor'e areas concerned is 13 years, and the greatest shell length is 65 mm.
