چکیده

speckled shrimp (metapenaeus monoceros), is a commercially important prawn in the embayments and estuaries of the mediterranean sea. it is originally a lessepsian species which had migrated from the red sea into the mediterranean sea through the suez canal. this study was carried out in the north-eastern mediterranean sea between november 2009 and october 2010 with monthly sampling of speckled shrimps, by bottom trawl operations. totally 784 specimens of this shrimp were studied, and the male/female ratio was determined as 1:1.4. the minimum size at first maturity for females was measured as 74 mm tl, and 50% of the female population were mature at about 110 mm (tl50%). it was also determined that female shrimps had developed their eggs between june to october, with two peak spawning periods between june-july, and august and october.

Population dynamics of the Metapenaeus monoceros (Fabricius, 1798) in North-eastern Mediterranean Sea

Monthly sampling of speckled shrimp was conducted by bottom trawl in the Iskenderun Bay between November 2009 and October 2010. There was a linear relationship between carapace length and total length in males and females (TL = -0.112 + 0.2294*CL R2 = 0.8298, n = 327) for males, (TL = -0.3918 + 0.2731 * CL R2 = 0.8919, n = 457) for females, and (TL = -0.378 + 0.2684 * CL R2=0.8492, n=784) for t...
