Description 1689-1694
Morphometric characters and reproductive biology were
studied in S. officinalis collected
at different seasons from the Iskenderun Bay, Turkey. A total of 2006 specimens
(992♀, 1014♂) were sampled from September 2005 to August using a Mediterranean
type deep trawl (22 mm
mesh size). Mean mantle lengths for female and male were 9.83±1.66, 9.40±1.76 cm and the mean
weights were 135.78±6.71g, 115.34±6.29g, respectively. Sexual maturity lengths
were calculated as 12.04 for females and 10.30 cm for males.  Mean diameter of eggs was measured as 5.367±9.12 mm per spawning period.
Spermatophore lengths were estimated to range from 2.8±1.05 to
12.4±2.11mm.   Population consisted of
gonochoristic induviduals. Although, sex ratio of Sepia officinalis were not significantly different from the
expected 1:1 ratio (p>0.05), a slightly male biased sex ratio was recorded.
