Detection of best stocking density of Penaeus indicus in the semi intensive system in Hormozgan Province

This study done for detection of best stoking density Of Penaeus indicus in intensive culture with corrporatiny Abzian Bandar Co. in northern Tiab area (Hormozgan Province) In this research measuring many factors in clude: Temperature, Dissolve oxygen, salinity, pH, turbidity, biometric and hygien of condition of shrimps. The results show Dissolve oxygen level in after noon suitable but not suitable in early mornnig for growths of shrimp. Salinity levels in early cycle of culture high an in middle to end cycle of culture decreasiy becuase in creasiny of water exchange. Turbidity level of water growths of shrimp is good and Temperature with pH of water ishigh in standard level. The resultes of hygien condition show that with in creasing density percentage of infections of bacteria and fungus and also parasites in creasiny. Also resultes show growth of shrimp very down beacuse period of culture very long and middle daily growth for all treatments down for 0.9 g Also persentaye Pie survival showes that treatment 18 -.with middle 97.3% have highest survival and more economically to other treatments. In spite of stocking density increasiny but increasiny but income from sale of shrimp decreased. Iranian Fisheries Science Research Institute Published
