One of the economically important species is Penaeus kerathurus (Forskål, 1755), which is widespread in the Mediterranean ecosystem. This paper presents results of research on reproductive biology of Penaeus kerathurus in the Sea of Marmara. A total of 1404 specimens were dissected to determine the maturity stages, reproduction time, and length at first reproduction. The female-to-male ratio was 1:0.9. A high percentage of mature females was determined in April, May and July. Moreover, the value of the gonadosomatic index (GSI) decreased after July. The spawning period was observed between April and July, and its intensity increased in July. The carapace length at first sexual maturity was determined to be 39 mm.

土耳其马尔马拉海中对虾（Peenaus kerathurus（1775年生于福斯科尔）（十足目：Penaeidae）的生殖生物学）

经济上重要的物种之一是角对虾（对虾，Forskål，1755年），该物种广泛分布于地中海生态系统中。本文介绍了马尔马拉海对虾对虾的生殖生物学研究成果。解剖总共1404个标本，以确定成熟阶段，繁殖时间和首次繁殖的长度。男女比例为1：0.9。在4月，5月和7月确定了很高比例的成年女性。此外，七月以后，性腺体指数（GSI）的值下降了。产卵期是在4月至7月之间观察到的，其强度在7月有所增加。初次性成熟时的甲壳长度确定为39毫米。
