Abstract

      Sexual cycle and biometry of date shell Lithophaga lithophaga were studied on samples collected from the area of Split (middle Adriatic) during 1987 and 1988. The results show that these shellfish are ripe and deposit their sexual products during the warmest part of the year (July, August and September) at sea water temperature over 22°C.

      Variations in weight of the flesh and shell are due to the changes in the relationship between shellfish growth, growth of somatic and gonad tissue, and loss of the material during spawning.
