ترجمة الملخص

This study deals with studying Biological Fecundity On Syrian coastal sea as introduction for it is breeding and culture.This research was achieved between September 2011 and -monthly samples were collected from littoral area by hand net and from sub littoral and Batuyal areas at depths to 600 m by Trawel. The samples were trans to postgraduate laboratory.The result of study shows that the mature female of Portunus occurrence during July and October and we did not find any mature female in January , March and December. The study shows that mature female increased of stages III, IV with carapace length and carapace width.The result of study shows that the mature female of Portunus place spring and the early winter months, with higher occurrence during October Absolute fecundity of female Portunus pelagicus was range 21435-143510 eggs , with CW:(5.2-13.8)cm, CL:(4.6-7.9)cm and BW:(49.2-171.45)gr.The relative fecundity was range : 1924-766651 eggs/gr from body weight .and the egg size range between 0.27-0.40 mm. The result of study shows a very strong positive correlation between (carapace long and body weight , carapace width and body weight) for female of Portunus result of study shows a very strong positive correlation between Absolute fecundity and (carapace width - –body weight) for the female that the value of correlation coefficients for all mentioned relations are higher that R>0.9.There were defined 34 species from order as following to tow suborder and tow and 15 Family, and 26 Genus.The highest value of temperature records was 30,1C° in September 2011 of Ebn Hanaa area, While the low est value of temperature records was 17,2C° in January 2012 of Alkornish Alganoby area. The high value of salinity records was 39,7‰ in August 2011 of Ebn Hanaa area, while the lowest value of Salinity records was 36‰ in January 2012 of Pore Fishing. The all values of PH was convergent from each other. The high value of D.O2 records was 6,68 mg/l in January 2011 of Almadina Alreadeaa are]a, while the low est value of D.O2 records was 4,60 mg/l in June 2012 of Pore fishing. There were defined 20 migrated species include 16 migrant from the Red sea and 4 species are western Atlantic , and 4 species for the first time we defined new : –Charybdis –Charybdis – .The number of important economic as regards the fisheries and culture as human foods resource are reached 11 species
