A study of the gametogenic cycle of the carpet shell clam, Tapes decussatus, was undertaken in the inside and outside of
Çakalburnu Lagoon, Izmir Bay, Aegean Sea from August 2006 to July 2007. Histological evidence showed that
gametogenesis of T. decussatus continued throughout the year and six stages of gonadal development were observed in two
sites. In males, except for November in inside and December and January in outside of lagoon ripeness (Stage III) clam was
observed during a year. In addition, spawning (Stage IV or Stage V) continued throughout the year in inside and except for
February and March in outside. In females, ripe clam (Stage III) was observed similar time with male in two sites. It was
observed that Stage 0 (inactive or resting) was only 3.0-5.0% ratio in November, December and January in two sites. The
male/female sex ratio for inside and outside of lagoon was 1:1.06 and 1:1.10, respectively (P>0.05).
