Sparidae family is one of the most important demersal group for Turkish fisheries. When considering importance Turkey fisheries, population parameters Pagellus acarne Risso, 1827 have a many proposition future fisheries studies. Studies biology and this species are very limited in Aegean Sea; therefore we aimed to determine (length-weight relationship, age growth parameters, mortality rates reproductive season) order obtain data We caught 2673 specimens between September 2006 2008 from monthly samples at depths ranging 20 500 m Saros Bay using commercial bottom trawl net. Total length weight range 3.5 27.1 cm, 1.93 314.5 g, mean were 14.0±0.05 35.6±0.46 g respectively. The length-weight relationship was detected W=0.001*L3.054, which indicated positive allometric growth. high GSI value September. on maturity stages that 50% (L50) females 18.1 cm TL males 15.3 TL. derived sagitta otoliths reading used estimate ranged 1-4 aged. von Bertalanffy total L?=30.63 K=0.26 year-1, to= -0.95. instantaneous Z= 0.72 natural M = 0.54 year -1, fishing F=0.19 year-1 exploitation ratio (E) stock found as 0.26. marine fish with both coast all Mediterranean basin.

High resolution simulations on the North Aegean Sea seasonal circulation

The seasonal characteristics of the circulation in the North Aegean Sea are examined with the aid of a climatological type simulation (three-year run with perpetual year forcing) on a fine resolution grid (2.5 km by 2.5 km). The model is based on the Princeton Ocean Model with a parameterisation of plume dynamics that is employed for the input of waters with hydrographic properties that are dif...
