  2. Stocking density, Survival rate and Growth performance feed utilization and economic evaluation of Litopenaeus vannamei , in different cultured shrimp farms in Suez Canal Region

  3. Survival Rate The survival rate in calculating by calculating the number of fish living at the beginning of stocking and end of maintenance, is expressed in percent. Survival rate can be calculated by formula (Jatilaksono, 2007) : SR = Nt No ×100% Information : - SR = Survival Rate - Nt = Final amount (ekor)
