Muğla-Ören mevkii’nden toplanan deniz kestanelerinin (Arbacia lixula) gonadosomatik ve vücut indeks değişiminde farklı metotların uygulanması

Abstract

Sea urchins which collected from Muğla-Ören site area were measured biometrical. Then body compartment dissected seperately. Gonadosomatic and body indices are worked out by different methods (Method 1= Wet gonad weight / total wet weight * 100. Method 2= Wet gonad weight / eviscerated test weight * 100. Method 3= Dried gonad weight /total dried body weight * 100. Method 4= Wet gonad weight /wet test+Aristo weight * 100) in a study on Arbacia lixula which is one of the edible species. It is determined due to the data that maximum gonadosomatic index is avaliable with method 3 (%5.79) and minimum one is (%2.58) with method 4 in other viewpoint, it is determined that maximum test index is avaible with method 4 (%91.67) and minimum one is (%62.92) with method 1, maximum stomach index is avaible with method 2 (%6.3) and minimum one is (%2.4) with method 3, maximum aristo index is avaible with method 2 (%9.08) and minimum one is (%5.71) with method 1 by using body index.
