DYNAMICS OF THE SETTLEMENT OF THE BIVALVE MYA ARENARIA L.
ON THE ROMANIAN SHORE OF THE BLACK SEA

Abstract
A number of 327 samples collected in 1972 between Constanta and 
Sulina from depths between the sea shore and 30 meters provided
data for establishing the qualitative and quantitative distribution 
of the bivalve Mya arenaria on the Romanian shore of the Black Sea.
Comparison of 1972 data with those obtained in previous years
showed that the settling of Mya at the Romanian coast was not a
completed process.
Penetration of the Corbula biocenosis by Mya involved no essential
qualitative or quantitative alterations in the aboriginal malaco-
fauna, the settling of this further bivalve bringing about an
increase in the biological output of the sites it occupied.
