ECOLOGICAL AND BIOLOGICAL STUDIES ON SOME ECONOMIC BIVALVES IN SUEZ BAY
Mostafa Ahmed Mohamed Mahmoud;
Abstract
A study was made from April 1999 to June 2000 of the economic clams in Suez Bay. Two species were investigated, Gafrarium pectinatum and Mactra olorina. The two species are dioecious, the sex ratio not varying significantly overall from
1:1, no hermaphrodites were obtained.
G. pectinatum matures at shell length of between 10-13
mm, while M. olorina matures at shell length of between 26.3-
31.5 mm. The relationships between shell length and several
growth parameters for both species were significant and reflected isometric growth in most cases.
Spawning period for the two species extends from March to June.
