Some biological parameters of pacific oyster <i>Crassostrea gigas</i> (Thunberg, 1793) in the Busse Lagoon (Sakhalin Island) in 2010–2020

Abstract

Size-age structure and spatial distribution of pacific oyster <i>Crassostrea gigas</i> in the Busse Lagoon (Sakhalin Island) in 2010–2020 are analyzed. The oyster colony is in depression. Height of the shells, weight and age of clams have decreased significantly during the decade of observations. The oysters with non-commercial size dominate in the colony.
