Investigation of fisheries and growth performance of clam Chamelea gallina (L., 1758) from West of Black Sea, (Kefken,Çatalzeytin), Turkey

In this study, the biometric parameters were examined of the specimen which sampled from open areas ( Doğanyurt, Kurucaşile, Kefken, Çatalzeytin, Cide, İnebolu) for 1640 Chamelea gallina, fishery during the October 2005- April 2006. Average lenght of examine all individual are been determinated 19,37. The mean lenght of C.gallina was mesaured 20,44 mm in October 2005- 20,16 mm in November 2005- 18,34 mm in December 2005- 18,73 mm in January 2006- 18,22 mm in February 2006-19,35 mm in March 2006 and 20,07 mm April 2006, respectively. The maximum and minumum lenght values were determinted as 11,0 mm and 29,0 mm, respectively. The maximum lenght frequency of individuals was % 85,67 with 16-22 mm. The maximum width frequency of individuals was % 21,65 with 17 mm. The total weight of C.gallina individuals maximum value 6,757 gr and minumum valve 0,373 gr. Maximum density of total weight distribution were between % 80,24 with 1 and 2,5 gr. The investigation, between `lenght- widht?, `length-thickness?, `total weight- meat weight? relationships were linears, where as ` lenght-total weight?, `lenght-meat weight? the relationships between were exponential. Correlation analysis biological parameters of C.gallina were positive and strong ranged between 0,66-0,92. Key Words: Chamelea gallina, striped venus, biometric parameters
