AI InsightRelationship between total weight (Wt) and gonad weight (Wg) in males and females were found as Wt=38.5+2.55Wg (R2=0.222) and Wt= 36.8+4.55Wg (R2=0.331), respectively.

In this study reproductive biology of Liza abu (Pisces Mugilidae) from Atatürk Dam Lake in the Euphrates River Basin was observed. Some reproductive characteristics such as age, egg number, sexual determination, gonadosomatic index (GSI) of Liza abu (n=821) are taken into consideration. The relationship between total weight (Wt), and total length (Lt) and fecundity (F) were investigated during the period from January 2004 to December 2005. The ages of investigated fish ranged from 1 to 5. The ratio of the numbers of fish samples with egg (89): total of female (413): total sample of Liza abu (810) were determined as 1:4.64:910 respectively. Though the highest gonad somatic index (GSI) of female was found in April, male's was highest in May. The relationships between the total weight (Wt) and fecundity (number of eggs= F), total length (Lt) and fecundity (F) of L. abu were found as Fw = 25.5+0.00583Wt (R2= 0.557) and FL= 14.2+0.000373 Lt (R2= 0.496) respectively. Relationship between total weight (Wt) and gonad weight (Wg) in males and females were found as Wt=38.5+2.55Wg (R2=0.222) and Wt= 36.8+4.55Wg (R2=0.331), respectively.
Abstract
In this study reproductive biology of Liza abu (Pisces Mugilidae) from Atatürk Dam Lake in the Euphrates River Basin was observed. Some reproductive characteristics such as age, egg number, sexual determination, gonadosomatic index (GSI) of Liza abu (n=821) are taken into consideration. The relationship between total weight (Wt), and total length (Lt) and fecundity (F) were investigated during the period from January 2004 to December 2005. The ages of investigated fish ranged from 1 to 5. The ratio of the numbers of fish samples with egg (89): total of female (413): total sample of Liza abu (810) were determined as 1:4.64:910 respectively. Though the highest gonad somatic index (GSI) of female was found in April, male's was highest in May. The relationships between the total weight (Wt) and fecundity (number of eggs= F), total length (Lt) and fecundity (F) of L. abu were found as Fw = 25.5+0.00583Wt (R2= 0.557) and FL= 14.2+0.000373 Lt (R2= 0.496) respectively. Relationship between total weight (Wt) and gonad weight (Wg) in males and females were found as Wt=38.5+2.55Wg (R2=0.222) and Wt= 36.8+4.55Wg (R2=0.331), respectively.
