sampled specimens was 1:1.31. Maturity stages were recorded on a monthly basis in both<br />
sexes. The highest monthly percentage of mature females (21%) and males (46%) was recorded<br />
in January 2005 and June 2005, respecti<strong>ve</strong>ly. The monthly and seasonal gonadosomatic index<br />
(GSI) results indicated that E. moschata shows two annual reproduction peaks for each sex. For<br />
males, the first spring peak occurs in March–June and the second, autumn peak is in<br />
No<strong>ve</strong>mber. For females, the first summer peak occurs in May–June and the second, winter<br />
peak is in January, respecti<strong>ve</strong>ly. On the other hand, the reproducti<strong>ve</strong> season extends from<br />
No<strong>ve</strong>mber to July with two peaks in the Aegean Sea. Total oocyte stock varied from 273 to<br />
2896 with a mean of 836 ±193 oocytes. The mean size of the oocytes was 6.26 ±0.10 mm. The<br />
maximum oocyte size found was 10.7 mm. The mean length of spermatophores was of 13.66<br />
±0.08 mm (range: 7.3–18.3) and their a<strong>ve</strong>rage number was 52 ±6 (range: 6–172).<br />

Reproducti<strong>ve</strong> Biology of the Bobtail Squid Rossia macrosoma (Cephalopoda: Sepiolidea) from<br />
the Eastern Mediterranean.<br />

Turkish Journal of Fisheries and Aquatic Sciences 10: 81-86 (2010)<br />
Abstract: Rossia macrosoma was in<strong>ve</strong>stigated based on material collected from the eastern<br />
Mediterranean Sea, to determine potential fecundity (PF), reproducti<strong>ve</strong> strategies and size at<br />
maturity. The female potential fecundity ranged between 126 and 931, while the value was 15<br />
to 103 for male spermatophores. Egg sizes varied from 0.2 to 10.0 mm, and spermatophore<br />
lengths ranged from 12.3 to 18.8 mm. Animals became mature at smaller sizes than those from<br />
the western Mediterranean, thus, their maximum sizes were smaller either. According to egg<br />
diameter distributions in gonads, R. macrosoma has asynchronous ovary maturation, spawning<br />
more than once. Therefore, R. macrosoma is an intermittent spawner similar to other sepiolid<br />
species.<br />
