Thisstudy was held in three months, which are from March until May 2015. The data analysis usethe ELEFAN I method (Electronic Lenght Frequencys Assesment Tool) which packed inFISAT II (FAO-ICLARM Fish Stock Assesment Tool).The samples of tamban are 721 whichconsist of 465 male tamban and 256 female tamban. The growth pattern of tamban is negativeallometric. The range of condition factor are 0,630 – 1,633.
