DISTRIBUTION AND SHELL HEIGHT-WEIGHT RELATION OF /i>RAPANA VENOSA VALENCIENNES IN THE LAIZHOU BAY
Abstract:
Rapana venosa is mostly distributed in the estuary in the Laizhou Bay and the shallow water of the sea board belt. From April to October, the population inhabits the shore, migrates to deeper habitats in winter. Its shell height is closely related to its weight (r = 0.93); the equation of regression curve is W = 1.8793×10-4L2.938. The weight increases with the growth in shell height.
